Slow Ethernet Upload (1.0 Mbps or less after Windows Update)

 

Slow Ethernet Upload

Some users may experience issues with slow upload (usually 1.0 Mbps, or near there) with Ethernet connections, especially after updating to Windows 10 1803 (April 2018 Update). This can typically be resolved by uninstalling and reinstalling the Killer Control Center after the Windows 10 1803 update. Here is the step by step:

  1. Download the Killer Software Uninstaller Tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe
  2. Download the installer for the Killer Control Center that is best for your version of Windows 10. You can check this by clicking Start, then type winver and press Enter.
  3. Run the Killer Software Uninstaller Tool. When it is finished, it will say RESTART REQUIRED.
  4. Restart your computer by clicking Power > Start > Restart
  5. Once your computer has restarted, run the Killer Control Center installer that you downloaded, and follow the prompts to complete the install.

Please note that the Killer Software Uninstaller removes files and folders from previous installations that will not be removed simply by uninstalling old versions.

If you wish to know more about the differences between the two versions of the Killer Control Center, please see this article - https://www.killernetworking.com/driver-downloads/kb/faq/100-which-killer-control-center-should-i-install

 

Prompts to Update Killer Control Center

 

Prompt to Update Killer Control Center

Users may see a prompt to update the Killer Control Center. This prompt is caused by a Windows Update that was not instigated by us but, nevertheless, targeted systems that came with the Killer Control Center preinstalled. Unfortunately, if you are here, you have probably already noticed that this prompt does not include any instructions on exactly how to update the Killer Control Center. 

The best way to eliminate this prompt is to manually update the Killer Control Center from our website. Here are the steps:

  1. If you are using Windows 10 and don't already know which build, find out which build of Windows that your machine is currently running. If your computer has completed the Windows 10 Spring 2018 update, you are running version 1803. Otherwise, or if you don't know, continue reading.
    1. Click Start
    2. Type winver and press Enter
    3. A box will appear with some information about Windows. There will be a 'Version" number. It will probably be either 1709 or 1803. 
  2. Download the correct installer for your version of Windows.
    1. Windows 7, Windows 8.1, and Windows 10 Version 1709 and below should download this installer - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
    2. Windows 10 Version 1803 and above should download this installer - https://www.killernetworking.com/driver-downloads/item/kcc-uwd
  3. Download the Killer Software Uninstaller Tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe
  4. Run the Killer Software Uninstaller Tool. It is not necessary to scan, and the scan may not find anything. Regardless, click Remove Killer Software, and give it some time to run. When it is finished, it will say "RESTART REQUIRED."
  5. Restart your machine by clicking Start > Power > Restart
  6. Once your machine has booted back up, run the installer that you downloaded for the Killer Control Center. Follow the prompts to complete the installation.

You should now have the latest Killer Control Center and device drivers installed, and should no longer see the update prompt. 

How to Update or Install The Killer Control Center

2.5 

Updating or Installing The Killer Control Center

The Killer Control Center installers contain drivers for the Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500. The Killer Control Center can be installed on any system with one, or multiples of these network adapters. It cannot be installed on machines with the E2100, Xeno Pro, 2100, M1, or K1. These are legacy devices that are no longer supported, and no longer receive driver updates. 

Click here to jump to troubleshooting steps.

The first step in updating or installing the Killer Control Center is download the correct installer package. There are currently two different Killer Control Center installers:

Choosing the Correct Installer

Those using Windows 7, Windows 8.1, and any version of Windows 10 prior to 1803 (April 2018 Update) should use this installer - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64

Those using Windows 10 1803 (April 2018 Update) or later should use this installer - https://www.killernetworking.com/driver-downloads/item/kcc-uwd

If you are using Windows 10, and you are unsure which version you are running, you can find out by clicking Start, then typing winver and pressing Enter. A box will appear, which will give you information about Windows, including the version number. 

For more details on the differences between the two packages, please see this article - https://www.killernetworking.com/driver-downloads/kb/faq/100-which-killer-control-center-should-i-install

Once you know which version to download, and have downloaded it, double-click the installer to install both the latest drivers for your Killer devices, and the latest version of the Killer Control Center. 

If all goes well, you can stop here. 

Errors or Other Issues When Installing

If you encounter any errors or problems when installing, first try uninstalling all versions of the Killer Software that are currently on your machine. We have developed a tool to make this very simple. Please follow the steps below:

  1. Download the Killer Software Uninstaller Tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe (please note that this is not the old Killer Remover tool - this is much more comprehensive)
  2. Make sure you have the installer for the Killer Control Center that you will be installing. Return here if you aren't sure. 
  3. Run the Killer Software Uninstaller Tool. There are two buttons - one for scanning, one for uninstalling. You do not have to scan. The scan might not find any software installations, but there may still be services installed on your machine that are preventing the installation of the current suite. Regardless of what the scan says, if you are having issues installing, make sure you click Remove Killer Software. When it is finished, it will say "RESTART REQUIRED"
  4. Restart your machine by clicking Start > Power > Restart
  5. Once your machine has completed restarting, run the installer for the Killer Control Center. 

If you are still unable to install the Killer Control Center, please try using Microsoft's tool for fixing problems that block programs from being installed or removed. You can find our guide for using this tool here - https://www.killernetworking.com/driver-downloads/kb/faq/90-microsoft-tool. This tool is very effective because, if you are still having problems by this point, the issue is very likely caused by files that have been shuffled around during a Windows Update. 

If the Microsoft Tool does not solve the issue, please submit a ticket to our support, along with an install log for us to analyze, by following these steps:

  1. Run the installer for the Killer Control Center one more time, so as to create the most recent possible information in the install log.
  2. After the installer fails, access your TEMP folder by clicking Start, then typing %TEMP%, then pressing Enter.
  3. Arrange the files in that folder by "Date Modified" so that the most recently modified files are at the top.
  4. You will see many files. Find the most recent file that begins with MSI and ends with .LOG. Move or copy that file to a place you will remember.
  5. Click Support > Contact Support at the top of our website, and be sure to click the folder and attach that .LOG file. In your ticket, please also mention any errors that you might have seen when attempting to install the Killer Control Center. 

Which Killer Control Center Should I Install?

 

Which Killer Control Center Should I Install?

Users may notice that we often host more than one version of the Killer Control Center available for download from our website. This article will summarize the difference between the versions available, and hopefully give the user an idea of which installer they should download and use. 

A note on device compatibility  -  All versions of the Killer Control Center support all Killer Wireless adapters, as well as the E2200, E2400, and E2500. The E2100, 2100, K1, M1, and Xeno Pro are legacy devices, and no longer receive driver updates.
A note on the Killer Network Manager - The Killer Network Manager is our deprecated performance suite. It does not contain current drivers. Users are free to use the Killer Network Manager if they like, but, as it is no longer in development, the first step in troubleshooting should be to uninstall the Killer Network Manager and install the Killer Control Center.
A note on finding your Windows version number - You will see Windows version numbers referenced in the following information. You can find your Windows version by clicking Start, then type winver and press Enter. You will see a box with information about your Windows install, including the Version, which is probably 1709 or 1803, as of June 5 2018. 

The current Killer Control Center versions are as follows, as of June 5, 2018:

What is this? This is our previous release, which was well tested and troublefree on Windows builds 1709 (Fall Creator's Update) and 1803 (April 2018 Update). This package contains the latest drivers for all Killer Networking devices, except for the Killer Wireless-AC 1550, as well as the Killer Control Center performance suite. The included driver for the Killer Wireless-AC 1550 is not known to be problematic, but our other package includes a more recent driver for this device.

What's new from the previous release? A new, updated driver for the Killer Wireless-AC 1550. 

Who should use this?  All Killer Network adapter owners who are using Windows 7 and Windows 8.1, as well as those using Windows 10, who have not yet updated to Version 1803 (Windows Spring Update), or who would prefer to not install the Killer Control Center through the Windows Store. 

What if this will not install? Click here for troubleshooting steps and scroll to the bottom to Errors or Other Issues When Installing

Special conditions for this release: Unlike the other package, this release uses a regular installer, and does not go through the Windows Store.

 

 

Killer Software Package - with Wireless xTend for Killer 1550 Version 1.7.1016
Release Notes

What is this? This version is a major update. This is our most recent release, which has been tested primarily with Windows 10 version 1803 (April 2018 Update). This package contains the latest drivers for all Killer Networking devices, as well as the Killer Control Center performance suite. The installer will first install device drivers, and then redirect to the Windows Store to install the Killer Control Center software. Please note that the version number listed here is the version of the installer. The version of the Killer Control Center that the Windows Store installs will be different. 

What's new from the previous release? A new, updated driver for the Killer Wireless-AC 1550, the debut release of Wireless xTend for Killer 1550, and many other minor enhancements that are too numerous to list.

No Killer Network Interfaces Connected

 

A few things can cause the Killer Control Center to report error. Following are the most common, and how to correct the issue:

  • You are connecting to the Internet using a network adapter other than a Killer product. Some machines ship with network adapters from multiple vendors. For example, your machine may have a Killer Ethernet adapter, but the wireless adapter may be from a different manufacturer, such as Intel. The Killer Control Center will not work with another brand's networking adapter. Be sure that you are connecting to the Internet using the Killer network adapter. Our performance suites only work connected to the Internet with our products. If your Ethernet adapter is a Killer Networking adapter, and your wireless adapter is not, then you will need to use an Ethernet cable to use the Killer Control Center. You can check to see which adapters you have installed by right-clicking Start, then clicking Device Manager, then double-clicking Network Adapters. If the only Killer Network adapter is listed as an Ethernet adapter, then you will need to use an Ethernet cable to use the Killer Control Center.
  • You are using an older version of the Killer Control Center. Some recent versions of the Killer Control Center experienced issues identifying some adapters. This has been resolved in current versions of the suite. Updating to the latest suite should resolve the issue. Even if you have a new machine, the version of the software that was installed on it when it was boxed may now be out of date. You can find the latest Killer Control Center here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64.
  • You are not connected to the Internet. You will receive this error if you are not connected to the Internet using a Killer Networking adapter. Note that if you are connected to the Internet using a virtual adapter of any kind, even if that virtual adapter is attached to a Killer Networking adapter, the Killer Control Center will show this message as it cannot work with a virtual adapter. 
  • You recently installed or updated the Killer Control Center and have not rebooted your computer. Rebooting should resolve the issue. Please note that, to restart, you should click Start > Power > Restart, as simply closing the lid, or pressing the power button on many modern computers activates sleep mode, and does not actually power down the machine. 
  • You are using a virtual network adapter. The Killer Control Center can only work if you are connecting to the Internet using a Killer Networking Adapter. If you are connecting to the Internet using a virtual adapter, the Killer Control Center will not work, and will show this message instead. 

If you are seeing this message and none of the above applies, please reach out to support, using the link below. Please be sure to include a diagnostic with your support request. With the latest Killer Control Center installed, you can find Killer Diagnostics in your Windwos start menu, under Killer Networking. Please run the application, save the output file, and attach it to your support request.

Error 1923 Verify That You Have Sufficient Privileges and Error 1939

4.8 

Error 1923 Verify That You Have Sufficient Privileges and Error 1939

Some users may encounter the error Error 1923: Verify that you have sufficient privileges to install system services and/or Error 1939 when they attempt to update or install the Killer Control Center. This is caused by the installer not being able to remove the previous version of the service. This appears to be due to the moving of files by the Spring 2018 Windows Features Update. There were also some updates that were incorrectly pushed through Windows Update that have resulted in the Killer Control Center being left in this state. In order to resolve this issue, you will need to uninstall the old version of the Killer Control Center, remove the service, and then run the installer again. We have developed a new tool, which will quickly and easily remove all old versions of our performance suite, as well as all old versions of our service from your system. 

A few notes about the Killer Software Uninstaller Tool:

  • This is not the Killer Remover tool that you might find elsewhere on the web and in this knowledge base. This is a brand new tool that we have just recently developed due to this issue. The old Killer Remover tool is not capable of resolving this issue, as it only targets pieces of installs that were broken by Windows Feature Updates prior to the 2017 Fall Creator's Update. 
  • This tool does not remove device drivers, other than what would normally be removed when running the uninstaller for the suite that you have currently installed. This tool primarily removes the Killer Performance Suite, and its attachments to Windows Update. 

Here are the steps to correct the Error 1923, Error 1939, or any other issue where Windows Update has put your machine in a state where you cannot install the Killer Control Center:

  1. Click here to download the latest Killer Control Center installer from our website. 
  2. Click here to download the Killer Software Uninstaller Tool (Updated May 24, 2018)
  3. Double-click the Killer Software Uninstaller Tool to run it.
  4. Click the Remove Killer Software button. This process may take some time.
  5. When the tool has finished removing everything, it will prompt you to restart your machine. Restart your machine by clicking Start > Power > Restart.
  6. Double-click the Killer Control Center installer and follow the prompts to install. 

Please note - some machines will stil show pending Windows Updates with "Killer" and/or "Rivet" in them. Now that you have removed the previous install, and installed the website version, these updates now refer to software that is not present on your system. They should either attempt to install, fail, and no longer show as "pending," or simply be removed from the list of pending updates. If these updates cause issues after you have installed the Killer Control Center from our website, please let us know!

If you have any further issues, please feel free to contact support directly by clicking Contact Support under Support at the top of the page!

Internet Problems With New Computers

5.0 

Internet Problems With New Computers

This article only applies to brand new computers using Windows 10.

Some users may experience issues with brand new computers with Killer Network adapters and the Killer Control Center or Killer Network Manager preinstalled. 

These issues are often caused by Windows automatically updating to the latest version of the operating system without giving the user the chance to update any preinstalled software or device drivers. This results in software, which was likely up to date at the time the machine was boxed by the manufacturer, running on a version of the operating system on which it was never tested, and may not be able to operate on correctly.

If the user notices that, after Windows has updated, their Internet performance is severely degraded, or they see bluescreen errors that are attributed to our software or drivers, they should uninstall the Killer Control Center or Killer Network Manager, make sure Windows is fully updated, and then install the latest version of the Killer Control Center

Here is the step-by-step:

  1. Right-click Start
  2. Click Apps and Features
  3. Find "Killer Performance Driver Suite" or any variation or variations, and uninstall it or them, restarting when required. 
  4. If a restart was not requested, restart your machine now by clicking Start > Power > Restart. Avoid using the power button on your computer, as it is likely mapped to sleep the machine, which will not work for this purpose.
  5. Windows 10 will install a basic set of drivers. This does not include any of the latency reducing and bandwidth prioritizing features of your Killer networking adapter, but it will serve to let you update everything. The only exceptions are the Killer Wireless-AC 1535 and the Killer Wireless-AC 1550.
    1. There may not be a built-in driver in Windows 10 for the 1535 if the machine is still on the original release build of Windows 10 when the user uninstalls the Killer Control Center. This is unlikely, as you will likely not have access to uninstall anything before Windows has updated itself well beyond this point. 
    2. The Killer Wireless-AC 1550 was released in 2018 and, as such, no version of Windows 10 previous to this time will have built-in drivers. 
  6. Make sure your BIOS and chipset drivers, at least, are up to date from your machine manufacturer's support site. 
  7. Make sure Windows 10 is fully up to date. To do this:
    1. Click Start
    2. Type Windows Update and press Enter
    3. Click Check for Updates
    4. Let your computer install whatever updates it finds. 
    5. Once it is finished, restart your machine by clicking Start > Power > Restart, even if it has not asked you to do so.
    6. Repeat steps A through E until your machine finds no updates just after restarting.
  8. Download the latest Killer Control Center package, which also contains the latest drivers for your Killer network adapters - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64 - and double-click to install. 
  9. If you notice any issues with your Bluetooth, and you have a Killer Wireless adapter (Killer 1435, 1535, 1525, 1550) download and install the latest Bluetooth driver from our website - https://www.killernetworking.com/driver-downloads/category/bluetooth.
  10. If your wireless access point (router or modem) seems to struggle with a new Killer Wireless adapter, either slowing down, restarting, or freezing, please first try unplugging the access point and plugging it back in. If that does not resolve the issue, the device likely needs a firmware update. For a wireless router that you own, please see the support for our specific device. For a wireless modem that is owned by your ISP, please contact your ISP and request that they update the firmware on your modem. 
  11. If you have a wireless router that continues to reset when the 1535 connects to it, even after you have updated the firmware, please see this article - https://www.killernetworking.com/driver-downloads/kb/faq/35-router-issues-with-1535.

If you encounter any further issues with your Killer adapters, please do not hesitate to contact us directly!

 

VPN Client Connectivity Issues

 

Shrewsoft and Other VPN Clients

Previous versions of the Killer Control Center had some issues with some VPN clients. These issues have been resolved with the current releases. 

We suggest you download the latest Killer Control Center, found here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64

Keep in mind that the Killer Control Center contains our latest drivers, and supersedes the Killer Network Manager that you might find pre-installed on your machine from the manufacturer. 

Once you have the latest Killer Control Center handy, please follow these steps: 

Note: It is important to be aware that, when troubleshooting, you should always shut down your computer by clicking the Start button in the lower left-hand corner, clicking the Power symbol, and clicking Shut Down. You should always reset or reboot your computer by doing the same, but clicking Restart, instead. The power button on most laptops, and some desktops, is not configured to shut the machine down, but rather to sleep the machine. Sleeping the machine does not accomplish the same thing as shutting it down or restarting it. 

  • Uninstall any Killer Performance Suite and Killer Drivers entries in your Apps & Features menu
  • Restart your machine
  • Run the installer package that you just downloaded
  • Restart your machine once more

You should now have the latest drivers, and the latest Performance Suite installed. This should resolve any issues with VPN clients connecting. Please let us know if this does not solve your issue.

Do I Need To Configure The Killer Control Center?

 

Do I Need To Configure The Killer Control Center?

Other than running the speed test, which should be done whenever the user is able to minimize other network activity, the Killer Control Center runs very well as a background application with no user input whatosever. Note that the Killer Control Center will ask for a new speed test for each new network connection. This is normal, and it will save the results for each individual network until the Killer Control Center is updated. The reason for this behavior is to get an accurate reading for the maximum allowable bandwidth from each network, as each network will have different limits. 

The Killer Control Center will run in the background and prioritize latency-sensitive applications, and throttle bulk downloads when you are at your maximum bandwidth on its own, without user interaction. It does this based upon a set of predetermined rules, which we update from time to time. The rules do not automatically update, but unless the user plays a lot of very cutting-edge games, or uses many newly released applications, these priorities do not fluctuate often.

The user can update these rules by updating the suite itself from the website, or by clicking ​Download Latest App Priorities​ in the Settings window in the Killer Control Center. However, we update the Killer Control Center often enough that it's probably best to just grab the latest suite from here - http://killernetworking.com/driver-downloads/item/killer-control-center-x64​ - so that the user also has all of the latest drivers, as well as adjustments for any Windows Updates. The user can also manually change the priorities in the Killer Control Center at any time. 

Internet Problems With New Computers With Killer 1550

 

Internet Problems With New Computers With Killer 1550

Some users may encounter issues with new computers with the Killer Wireless-AC 1550 installed. These issues can usually be resolved by updating the Killer Control Center to the latest version, available here - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If you are unable to download the updated package, click Settings in the Killer Control Center, and toggle Advanced Stream Detect to Off. This will temporarily disable all latency reducing and bandwidth prioritizing features from your Killer networking adapter, but should allow you to download the updated package. Once you have the latest Killer Control Center downloaded, double-click it to begin the install. When the install is complete, Advanced Stream Detect will be activated by default. 

Service Not Running

 

Error: Service Not Running

You may experience a situation where their Killer Control Center says "Service Not Running" instead of operating normally. 

service not running

 

This issue should be resolved with the current build of the Killer Control Center. You can download the latest build of the Killer Control Center from here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. In most cases, you can simply download and install the update, and you will have the latest application and drivers. If you encounter an error, such as "Cannot be installed with..." or some other error, try removing all "Killer Suite" and "Killer Drivers" applications, as well as any variations, from your Apps and Features menu, then restart your machine, and try installing the update again. If you are still unable to install the update, refer to our troubleshooting article for issues installing the Killer Control Center here - http://www.killernetworking.com/driver-downloads/kb/cat/7-installing-and-updating#anchor2. You can also reach out to us directly here - http://www.killernetworking.com/about/contact.  

If updating the suite does not solve the issue, then you will need to investigate why the service is not starting automatically. If the service does not start automatically when the machine starts, then there is likely another service that is preventing it from starting, or the service is not set to start automatically

You can check to make sure that the service is set to run automatically by following these steps:

  1. Click Start, type services.msc and press Enter.
  2. Scroll until you find the Killer Network Service and double-click it.
  3. Make sure the "Startup Type" is set to Automatic. You can also manually start it from here by clicking Start button, which will clear the error until you next restart your machine.

Antivirus suites can also cause issues with services. Try completely uninstalling your antivirus suite and restarting to see if that solves the issue. If the service starts without the antivirus suite installed, reinstall the suite using a freshly downloaded copy from the suite's website. The service may still start automatically after you have reinstalled the antivirus application. If it does not, please contact us at http://www.killernetworking.com/about/contact to let us know which antivirus suite is blocking our service from starting, and also contact your antivirus application's support to find out how to add our service to the list or exclusions. 

If our service still does not start, and you still receive the "Service Not Running" error with no antivirus installed, and while using the latest Killer Control Center, please reach out to us at http://www.killernetworking.com/about/contact so that we may assist you further.

Bandwidth Test Error in Killer Control Center

 

Bandwidth Test Error in Killer Control Center

Users may notice that the built-in bandwidth test no longer functions in some versions of the Killer Control Center. This is due to changes in the way that the Killer Control Center connected to the servers that are needed to perform these tests. The current version of the Killer Control Center should not experience this issue. To resolve this issue, please update your version of the Killer Control Center by downloading the latest package from here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If the version on your system is old enough, the installer may give you an error, and you will need to manually uninstall the previous version before installing the latest package.

Error 2753: The File 'xtendsoftapservice.exe' is Not Marked for Installation

 

The File 'xtendsoftapservice.exe' is Not Marked for Installation (Error 2753)

This guide also fixes the error "The feature you are trying to use is on a network resource that is unavailable..."

Some users may encounter this, or a similar error, when updating their drivers or Killer Control Center, or when uninstalling the Killer Control Center.

Even if you are in the process of updating the Killer Control Center, the issue is that the installer is unable to find this file in order to uninstall it, which is a necssary step for installing the latest suite.

The problem is that the file is either not present, or is not correctly flagged in the registry. This is a bug that was introduced in a few versions of the suite when it was present on your machine during a major Windows feature update, or an upgrade to Windows 10 from another version.

Note that this guide can also be used to uninstall some older versions of the application, which have become bugged due to Windows Feature Updates, and may or may not appear in the Apps and Features menu. The process is exactly the same. 

This issue can be resolved by following these steps:

  1. Download the latest Killer Control Center and keep it somewhere handy, to install when you're finished uninstalling the old suite - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
  2. Download Microsoft's tool for fixing problems that block programs from being installed or removed - https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed 


    microsoft uninstall fixit2

  3. Once you have both of those things downloaded, uninstall all Killer products from your Apps and Features menu, which you can access by right-clicking Start.


    right click start uninstall killer

  4. You may encounter that same error - Error 2753. The File 'xtendsoftapservice.exe' is Not Marked for Installation - and that is fine. When you do, skip that application, and uninstall any other applications from "Killer" including "Killer Drivers."

  5. Now run the tool from Microsoft. 

  6. For the first menu, you will simply click Next


    ms uninstall fixit 1

  7. Then after a moment of "Detecting Problems", it will ask if you are having a problem installing or uninstalling a program. Even if you are trying to update or install the Killer Control Center, the actual problem is happening when the installer attempts to uninstall the old suite, so you will choose Uninstalling


    ms uninstall fixit 2

  8. At the next prompt, the program will ask you to choose from a list of programs. Find the Killer-related program in the list. It may not be the same as the one in this screenshot, but choose whichever Killer suite the program finds, and then click the Next button. 


    ms uninstall fixit 3

  9. The tool will then proceed to erase the parts of the Killer suite that the installer was unable to remove from the registry. If the program is not listed, you have the option of choosing "Not Listed", and the tool may still find the pieces in the registry that need to be removed. However, it is hard to duplicate that particular scenario, so providing a screenshot is not possible, but it is fairly self-explanatory. 
  10. Once the tool has finished doing its work, you will want to restart your machine once more, and then install the latest Killer Control Center, which you downloaded previously.
  11. If you have any further questions, feel free to contact support at the link below! 

The Feature You Are Trying To Use Is On A Network Resource...

 

When updating the Killer Control Center, you may encounter the error "The feature you are trying to use is on a network resource that is unavailable..." 

the feature you are trying to use

This issue can be resolved by using Microsoft's tool for fixing problems that block programs from being installed or removed. Although it may seem like the issue is happening when you are installing the Killer Control Center, the problem is actually happening when the installer is attempting to remove pieces of older installs, so you will need to choose Uninstalling when prompted. A detailed guide for using this tool is availabie here - http://www.killernetworking.com/driver-downloads/kb/faq/34-error-2753-xtendsoftapservice. Although the article does not talk about this issue specifically, the guide and fix is exactly the same. 

Removing The Killer Control Center

1.0 

How Do I Remove The Killer Control Center?

We understand that some of our users might prefer to use a driver-only solution. However, the Killer Control Center is designed to do its job with minimal necessary input from the user, and with a small resource footprint, so if you are encountering any problem that you suspect is caused by the Killer Control Center, we highly encourage you to reach out to us and let us know by contacting support here - http://www.killernetworking.com/about/contact. We generally reply very quickly, and our small and agile team of dedicated QA and support staff work together to duplicate and fix issues, often within days of discovery. In addition, did you know that the Killer Control Center can help speed up your browsing experience, even if you aren’t gaming? Our prioritization technology will, on connections with limited speeds, such as shared hotel Wi-Fi, slow background downloads like Windows Update, in order to streamline data moving to your browser, which can have an enormous impact on web surfing speeds on slow and spotty connections. Of course, gaming comes first, but when you aren’t gaming, we still want your machine to be as responsive as possible! However, if you would still rather use a driver-only solution, we do have that option available. You can download the driver-only packages here - http://www.killernetworking.com/driver-downloads/category/other-downloads - then uninstall the Killer Control Center, restart your machine, and run either the bare driver installer, or install the .INF file with your Device Manager, depending on which package you opted to download.

 

Network Column in Windows Task Manager Not Working

 

For our software to display bandwidth correctly, Windows NDU (Windows Network Data Usage Monitoring Driver) ends up getting stopped/disabled. This is because both services work by examining packets, and both doing so at the same time can cause conflicts.

If you force NDU to run while Killer Control Center or Killer Network Manager is installed, those two programs may not display bandwidth correctly.

If you would like to re-activate the Windows NDU to test for yourself, open a Command Prompt and enter the following:

sc config ndu start=auto

After you enter that command, reboot your Computer.

NDU should now be set to start automatically and the Task Manager Processes tab should show traffic in the Network column, but the Killer Control Center or Killer Network Manager might not work properly.

To disable it, enter the following into a Command Prompt:

sc config ndu start=disabled

After you enter that command, reboot your Computer.

No Killer Enabled Devices On Linksys WRT32X and WRT32XB

 

Users with Killer Network Adapters and the Linksys WRT32X may see "No Killer Enabled Devices" or "0 Killer Enabled Devices" on the user interface page of their WRT32X. 

The Killer optimization on the WRT32X is compatible with all Killer adapters that work with the Killer Control Center, which includes the:E2500, E2400, E2200, E2201, and all of our Wireless-N and Wireless-AC adapters. 

Please note that Windows 8.1 or 10 is required on the Killer enabled device for the router to label it as such in the router's interface. The router will still prioritize the Windows 7 Killer enabled device, but it will not appear that way in the router interface. 

You must also have a recent version of the Killer Control Center installed. You can find the latest version of the Killer Control Center here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If you run into any problems updating your performance suite, you can refer to our installation troubleshooting KB here - http://www.killernetworking.com/driver-downloads/kb/faq/6-troubleshooting-killer-ethernet-wireless-drivers-software.

After you have installed the latest Killer Control Center, if the router still fails to detect the Killer adapters, you may need to unplug the router for ten seconds, then plug it back in. If it still does not recognize the adapters. you may need to restart your computer once more by clicking Start > Power > Restart

Consoles will not appear as Killer Enabled Devices, even on the WRT32XB. The unlike the WRT32X, however, the WRT32XB will identify the XBOX ONE by name. You can then assign it priority within the router's UI. 

If you still experience issues, it is recommended that you contact Linksys Support unless you are having other issues with your Killer adapter, in which case you should reach out to us through the contact form below. 

 

Memory Leaks

 

Some users have reported memory leaks with some versions of our performance suite. The current version of the Killer Control Center has no known instance of memory leaks. Unfortunately, when a computer is assembled, the software that is installed on the computer will not necessarily be up to date when the user unboxes the machine. This means that the user will need to update the software. Various computer manufacturers test and provide various versions of our software on their own support pages at their discretion, so the version of our software that you might find elsewhere on the web may not be the most up to date. If you are experiencing memory leaks, we highly suggest downloading and running the latest Killer Control Center installation package direclty from us, from this location - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If you experience any memory leaks, or any other issues with the latest Killer Control Center, please reach out to us at the contact information below.
