Clean Install The Killer Control Center

There have been many reports of issues with the Killer Control Center which can be resolved by performing a clean install of the Killer Control Center, as opposed to an update install, where the latest version is installed while an older version is in place. When troubleshooting, this is a good place to start. Here are the steps to perform a clean install of the Killer Control Center:

  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, or those using a Wireless-N device, should download this installer - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
    2. Thos using Windows 10 Version 1803 and above should, and not using a Wireless-N adapter, 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. Restart your machine by clicking Start > Power > Restart
  5. 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."
  6. Restart your machine by clicking Start > Power > Restart
  7. Once your machine has booted back up, access  your temporary files folder and delete the contents
    1. Click Start
    2. Type %temp% and press Enter. Your temp folder should open.
    3. Delete all files in the temp folder. These are all temporary install files, and are safe to delete. If you receive a prompt saying that a file cannot be deleted, you can safely select Skip All
    4. Close the temp folder
  8. Run the installer that you downloaded for the Killer Control Center. Follow the prompts to complete the installation. 
  9. Restart your machine if the installer requested a restart.
  10. Test to see if the issue is resolved.

If you cannot install the latest Killer Control Center because you receive an error that says that the current package cannot be installed with one of our older packages, even after using this clean install guide, please see our guide for "Cannot Be Installed With" Errors. 

"Cannot Be Installed With" Errors

 

"Cannot Be Installed With" Errors

Users may encounter the following errors, potentially among others, when attempting to update or install the Killer Control Center:

  • Killer Performance Driver Suite cannot be installed with Killer Ethernet Performance Suite (or similar) and you have already tried our Clean Install Guide.
  • Any other install errors where the current suite cannot be installed with another of our products, after you have tried our Clean Install Guide.

Even if you are in the process of updating the Killer Control Center, the issue is that the installer is encountering parts of an old Killer Performance Suite, and is unable to uninstall them. 

This issue can be resolved by following these steps:

  1. Download the latest Killer Control Center and keep it somewhere handy - https://www.killernetworking.com/driver-downloads/kb/faq/22-update-killer-control-center
  2. Doule-click the installer for the latest Killer Control Center. Let it fail. Do not restart your computer, even if asked. 
  3. 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

  4. 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

  5. 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."

  6. Now run the tool from Microsoft. 

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


    ms uninstall fixit 1

  8. 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

  9. 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

  10. 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. 
  11. 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.
  12. If  you are unable to fix the issue with this guide, try running through it again, but this time, choose Installing at step 7. This may help clear corrupted files that are not related to Killer components, but are still preventing the install.
  13. If you have any further questions, feel free to contact support at the link below! 

Windows Update Slowed Or Broke Internet Connectivity

 

Windows Update Slowed Or Broke Internet Connectivity

Update September 15 2018 - Windows 10 1809, which is currently being released in October 2018, seems to have caused many of these issues since its release. If you are unable to resolve this issue by following this knowledge base article, you may need to revert your operating system back to the Windows 10 1803 to restore functionality. While we do not yet have a guide for this, there are quite a few around the web, such as this excellent guide for rolling back to Windows 10 1803. 

Windows users will periodically run into situations where a Windows Update either slows or completely removes their ability to connect to the Internet. This is usually due to some component of the updated operating system not functioning well with older drivers, though sometimes Windows Updates have been known to just break things for no reason. In the past, Microsoft has even recalled some updates. Whatever the reason, if you know that your machine was working well before the Windows Update, the best way to restore functionality is often to remove that Windows Update. There are a few ways to do this.

First, you should check Device Manager and make sure it's not a simple error. To do that, right-click Start, click Device Manager, then double-click Network Adapters and look for your network adapter, be it a wireless adapter or an Ethernet adapter. If you find your network adapter, and it has a Code 10 error on it, then click here for a guide to manually install a driver for the device. If that's not the issue, or if that doesn't fix it, read on.

Try System Restore First

This is the fastest, easiest way to get your system back in working order, when it's available, and when it works. Luckily, if it doesn't work, it won't do anything at all. Here are the steps:

  1. Temporarily uninstall any third party antivirus application as these will almost universally prevent System Restore from restoring properly, resulting in an error. 
  2. Click Start
  3. Type system restore and click Create a Restore Point (don't worry, you're not doing that, that's just what comes up)
  4. Click the System Restore button.
  5. Check the "Recommended restore" option to make sure the date is very close to when the Windows Update happened, but still before it happened. If so, click Next.  If not, you can click "Choose a different restore point," but those will usually be earlier dates, if any. 
  6. There may be another confirmation prompt or two, depending on your build of Windows, but after that, System Restore should do its thing. This can take a while, so be patient. 

Uninstall The Windows Update

  1. If the System Restore doesn't work or isn't available, you will need to uninstall the Windows Update. This works surprisingly well and generally does not have many drawbacks, though making a back-up is definitely recommended. After you make your backup, you will want to set a System Restore point, as they are much faster and easier to use than restoring a backup, if necessary. Creating a System Restore point is similar to using one:
    1. Click Start
    2. Type system restore and click Create a Restore Point
    3. Check to make sure your system disk, probably (C:), has Protection "On". If not, click it Configure, and click Turn on System Protection, move the slider until it's using around 5% - 10%, then click Apply > OK. 
    4. Click Create
    5. Name it something you'll remember, like "Uninstalling Windows Updates." It will append the date, so you'll also have that information. Click Create and give it some time to finish.
    6. Once it is finished, close the "System Properties" window that opened when you searched for System Restore.
  2. Now to uninstall that update. This is surprisingly easy when you know where to look. Click Start, and type Windows Update.
  3. Click Windows Update Settings
  4. Click View Update History
  5. Click Uninstall Updates
  6. Click the Installed On column header to sort by the Installed On date until the newest updates are at the top. 
  7. This part is important. Even though you sorted by newest updates, you're probably still not looking at updates for Microsoft Windows. Instead, you're probably looking at updates for Microsoft Office, or Microsoft Visual C++, or possibly some other Microsoft product that you didn't even know you had. You can tell because, just under "Name", it will list the name of the application with no other information to its right. Scroll until you find Microsoft Windows, and you will have found the updates that we're looking for.
  8. You will want to uninstall any update that took place between now and when your machine last worked normally. To do that, click the update, and click Uninstall, which will hopefully appear beside "Organize" at the top of the columns. If the option to uninstall does not appear, this means that you cannot uninstall that update and keep your operating system intact. The same goes for updates that are not listed. 
  9. If you are unable to uninstall the update, you may have to resort to restoring a backup or, if that's not possible, resetting Windows. Click here for Microsoft's article on resetting Windows. However, if the only issue that you are having is with your Killer products, please reach out to us first at killersupport@rivetnetworks.com so that we can see if we can help you out. 

Update Your Drivers As Soon As You Have Internet Access!

As soon as you are able to restore Internet access, be it with a System Restore, a backup restore, or uninstalling the Windows Update, make sure you update your drivers! This should prevent the issue from happening when Windows Update invariably installs the same update again in the future. You can find our driver downloads here - https://www.killernetworking.com/killersupport/ - and if you have any issues installing the latest Killer Control Center and device drivers, we suggest using our clean install method here - https://www.killernetworking.com/killersupport/driver-downloads/kb/faq/105-clean-install-the-killer-control-center.

Will The Killer Wireless-AC 1550 Work In My Laptop?

 

Will The Killer Wireless-AC 1550 Work In My Laptop?

Many users have emailed us asking if the Killer Wireless-AC 1550 will fit in their laptop. (Click here to find out if the 1550 will fit your desktop.) Although we cannot know the exact specifications of each make and model of laptop, even if we have the model numbers for said laptops, we can give you some basic guidelines.

Look Up The Wireless Adapter That Your Machine Is Currently Using To See If It Uses A PCIe Half Mini Adapter, or An M.2 Adapter

To do this, right-click Start, click Device Manager, then double-click Network Adapters. You should find a wireless adapter listed there. Comparing to that adapter is the easiest way to know what will work in your system.

The Killer Wireless-AC 1550 is an M.2 adapter which uses IPEX-MHF4 antenna receptacles.

If your machine is using a Killer Wireless-AC 1525, 1435, or 1535, then the 1550 will almost certainly work as a replacement/upgrade. Please see manufacturer caveats below. 

If your machine is using a Killer Wireless-N 1102, 1103, or 1202, it will definitely not work as a replacement/upgrade, as these are PCIe Half Mini adapters. 

If your machine is using another brand's wireless adapter, you will need to find out if that adapter is an M.2 adapter that uses IPEX-MHF4 antenna receptacles. If it is not an M.2 adapter, then the 1550 will not work in its place. If the antennas are different, then the antenna leads will not fit onto the 1550 without modification, which may include cutting and splicing wires.Official websites are good sources of information, but you can also find information on shopping websites, such as Amazon and eBay, as resellers have a vested interest in providing accurate information about the product they are selling. Just make sure to verify with a few listings. For 100% verification, you will need to contact the machine manufacturer to find out what interface and antenna conections it uses for Wi-Fi. 

You can also open the machine up to verify whether the machine uses an M.2 slot for its Wi-Fi adapters. Below is an image comparing a PCIe Half Mini and an M.2 adapter, the two most common formats with modern Wi-Fi adapters.:

Manufacturer Caveats

There are two other things that need to be verified before you know for sure if switching Wi-Fi adapters is an option. Only the machine manufacturer or, potentially, their support community, can tell you these things.

  • Does the machine employ Wi-Fi lockouts? Some machine manufacturers have lockouts, which are built into the BIOS, that will either prevent the machine from booting, or prevent the wireless adapter from working, if an adapter other than the original is used. 
  • Is the Wi-Fi adapter soldered in? Some machine manufacturers solder down the Wi-Fi adapter. In these machines, even though they are using a normal slot for the Wi-Fi adapter, the adapter cannot be removed.

Other Considerations

  • Linux Support - The Killer Wireless-AC 1550 uses the iwlwifi driver, which is widely supported in nearly every Linux distribution. However, only the latest versions of this driver contain the hardware ID for the 1550, so only the latest Linux kernels support the 1550. Without the advanced Linux expertise required to patch the driver and rebuild the kernel, Linux support is still limited. 
  • Windows Support - The Killer Wireless-AC 1550 is not supported in Windows 7 or Windows 8.1. It is only supported in Windows 10. The Wireless xTend feature is only supported in Windows 10 1803 (April 2018 Update). 

How to Update or Install The Killer Control Center

 

Updating or Installing The Killer Control Center

The Killer Control Center installers contain drivers for the Killer Wireless-AC 1525/1535/1435, 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.

Only the non-UWD version of the Killer Control Center that is downloaded from our website is compatible with our Wireless-N adapters - the Killer Wireless-N 1202/1103.

 The Killer Control Center 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. 

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 a Killer Wireless-N adapter, Windows 7, Windows 8.1, and any older build of Windows 10 prior to 1803 (April 2018 Update) should use our website installer - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64

Those using Windows 10 1803 (April 2018 Update) or later should use the UWD installer, as long as they are not using a Wireless-N adapter - https://www.killernetworking.com/driver-downloads/item/kcc-uwd

Please note that the UWD installer is fully compatible with the E2200, E2400, E2500, Killer Wireless-AC 1525, 1435, 1535, 1550, and 1550i adapters, as well as all of our forthcoming adapters in 2018 and beyond.

Wireless xTend, a new feature of ours, is only compatible with the 1550, and will only appear if you use the UWD installer and have a 1550 installed.

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. Restart your machine by clicking Start > Power > Restart
  4. 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"
  5. Restart your machine by clicking Start > Power > Restart
  6. 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 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. 
A note on device compatibility  -  The E2100, 2100, K1, M1, and Xeno Pro are legacy devices, and no longer receive driver updates. They are not supported with either of these packages.

The current Killer Control Center versions are as follows, as of August 3, 2018:

Error 1923 Verify That You Have Sufficient Privileges and Error 1939

4.9 

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 
  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!

 

Installing the Killer 1550 with an M.2 to PCI-E Converter

 

Installing the Killer 1550 with an M.2 to PCI-E Converter

The Killer Wireless-AC 1550 can be used in some M.2 to PCI-E converters, allowing desktop machines with open PCI-E slots to use the adapter, provided the following conditions are met.

  • The Killer Wireless-AC 1550 can only be used in PCI-E 1x or PCI-E 4x slots. It cannot be used in the longer PCI-E 8x or PCI-E 16x slots. Using an incorrect PCI-E slot can cause the 1550 to either not appear in Device Manager, or to appear in Device Manager with an error, or a bang symbol.
    pcie
  • For Bluetooth, a USB cable must be run between a USB 2.0 header on the motherboard and the USB header on the converter. If this is not connected, Bluetooth will not appear in Device Manager at all, and will not be usable. 
  • We cannot recommend any specific PCI-E converters. These are usually available from various vendors on Amazon, and most of them seem to work well, but they are typically unbranded, so buy at your own risk.
  • Please note that the Killer Wireless-AC 1550 is only compatible with Windows 10.

The E2100, 2100, and Xeno Pro are legacy devices, and no longer receive updated device drivers. Please contact the manufacturer of your Killer 2100, Killer E2100, or Xeno Pro for the latest drivers. The same driver (either 32bit or 64bit) works for each product. It has been confirmed that the latest drivers for Killer 2100, Killer E2100, or Xeno Pro can be downloaded on VisionTek’s support page at: https://www.visiontek.com/support/download-drivers.html. If you are using Windows 10, and Windows does not automatically install drivers for the device, the Windows 8.1 drivers should work for your application.

There is no Windows 10 driver for the E2100, 2100 and Xeno Pro, and there will be no further driver development.

Support is no longer available for the Killer M1 and Killer K1. 

How to Update or Install The Killer Network Manager

4.0 

Updating or Installing The Killer Network Manager

The Killer Network Manager is our outgoing performance suite. It is no longer being updated, and does not contain the latest Ethernet or Wi-Fi drivers. We encourage all users of the Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500 to upgrade to the Killer Control Center. This includes users whose machines came with the Killer Network Manager preinstalled. There is no need to continue using the Killer Network Manager. 

For a smooth installation, we recommend using our clean install method of installing the Killer Control Center, which will use our software remover to remove all previous versions of our suites. You can find our guide, and links, here - https://www.killernetworking.com/killersupport/driver-downloads/kb/faq/105-clean-install-the-killer-control-center.

The old Killer Network Manager suite is still available for download here - https://www.killernetworking.com/killersupport/item/e2200-e2400-wireless - but will no longer be updated, and may not be fully compatible with future Windows updates, antivirus suites, or other applications that manipulate network data. The final update of the Killer Network Manager was April 7, 2017. 

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! 

Issues When Installing Windows 7 Drivers

5.0 

Users may encounter errors when installing drivers in Windows 7. This can be resolved by installing an update to Windows 7 that enables SHA-2 code signing in Windows 7, allowing the older operating system to use the newer device drivers. If allowed to fully update, Windows Update should install this update for you automatically. However, if you are unable to connect to the Internet, you may need to use a USB thumb drive, or some other media, to install this update on the machine on which you wish to install Windows 7. You can read more, and find the appropriate update for your situation here - https://docs.microsoft.com/en-us/security-updates/SecurityAdvisories/2015/3033929

Windows Server Drivers

 

Windows Server Drivers

From time to time, we receive requests for Windows Server compatible drivers for our network adapters. Although we do not provide package installers for Windows Server editions, our drivers are Windows WHQL certified, and as such will work with recent Windows Server editions, so long as they are installed manually from the Device Manager using our .INF files.

You can download the .INF files from this location - http://www.killernetworking.com/driver-downloads/item/killer-drivers-inf

If you need assistance manually installing the .INF files using Device Manager, you can follow our guide here - http://www.killernetworking.com/driver-downloads/kb/faq/10-installing-drivers-device-manager

If you encounter an error when installing the .INF drivers for a wireless adapter, you may need to enable wireless networking in your Windows Server. This applies to all Windows Server editions, 2008 and beyond. To do this:

  1. Access Powershell from your administrator account
  2. Type Install-WindowsFeature -Name Wireless-Networking and press Enter. You should receive a confirmation that the service is installed, and a warning that the machine needs to be restarted.
  3. Type Restart-Computer to restart.
  4. Once the machine has restarted, access Powershell from your administrator account again. 
  5. Type net start wlansvc to start the wireless networking service.
  6. The .INF drivers should now install normally.

The Killer Control Center is not availalbe on Windows Server editions. 

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. 

How Do I Avoid Breaking Antenna Cables When Changing M.2 Adapters?

 

How Do I Avoid Breaking Antenna Cables When Changing M.2 Adapters?

Please note that any time you choose to change your Wi-Fi module, or any of your machine's hardware, you do so at your own risk and liability. 

M.2 WiFi modules and their connectors continue to get smaller as system providers continue to make thinner notebooks. This makes it much more difficult to disconnect the antenna lead from the module by hand when changing M.2 adapters. In order to properly disconnect the antenna from the module, all wireless module makers now recommend using a specially designed tool. For the Killer Wireless AC modules, we recommend using an IPEX MHF4L 90609-0001. This will greatly reduce the chance of damage to the wireless module connector or to the antenna connector.

If you are unable to obtain such a tool, be sure you pull the antenna leads straight up off of the connectors, to avoid breaking the connectors off of the card. Using a jeweler's or eyeglass repair screwdriver to very gently pull upward on the connector from beneath is best. When attaching antenna leads without a tool, try placing the adapter on a flat surface, lining the leads up on the receptacles, and then pressing down firmly, but gently, with a flat object, so that even pressure is applied. You should hear or feel a click when the the connector goes into place. Very little pressure is required so, if you find yourself pushing hard, you may be damaging the antenna connectors!
