Priority Not Set Correctly For Game/Application

Some users may find applications, games, or services whose priorities are not set correctly in the Killer Control Center. Although the Killer Control Center usually has the correct priorities preset for most applications, games, and services, there may be some that we have missed, and that the detection engine also does not find. 

If you find one of these, first make sure that you have the latest application priorities by clicking the Download Latest App Priorities in the Settings page of the Killer Control Center. This will ensure that you have the latest priorities that have been changed since the most recent version of the Killer Control Center was released.

If the priority for the application is not correct after updating, please send us an email to killersupport@rivetnetworks.com with the following subject - "KCC Priority." In the body of the email, please include the following:

  1. Application Name
  2. Application Executable (This can be found by hovering over the application in the Killer Control Panel, or looking in Task Manager under the Details tab. It will be a file that ends in .EXE. 
  3. Current Priority 
  4. Suggested Priority (1-6, remembering that, when using DoubleShot, Priority 6 uses Wi-Fi)

You can change the priority manually in the Killer Control Center by clicking the drop down box beside the application name, and selecting a number 1-6, with 6 being the lowest priority. 

Killer Control Center Does Not Automatically Start

2.9 

Killer Control Center Does Not Automatically Start

Due to the wishes of our hardware partners, the UWD version of the Killer Control Center does not start automatically. 

It is not necessary for the Killer Control Center to load in order for our software to do its job so long as the Killer Network Service is loaded. The Killer Control Center is your user interface for the Killer Network Service. The Killer Network Service is what does all the work, reducing latency and prioritizing applications. By default, the Killer Network Service automatically loads with Windows. There is nothing wrong with leaving the Killer Control Center unloaded until you wish to use its interface, or change application priorities. However, if you would like to set the Killer Control Center to start automatically, you can do so by following these steps:

  1. ​​Right-click Start
  2. Click ​Run
  3. ​Type ​shell:startup​ and press Enter
  4. Move the Startup window to the right side of your screen
  5. Click Start
  6. Locate the Killer Control Center Icon in your Windows Start Menu, under K. 
  7. Click and drag the Killer Control Center icon over to the Startup window
  8. Right-click the Killer Control Center shortcut that you have created in the Startup window and click ​Properties
  9. Click the drop-down box beside "Run" and change it to ​Minimized
  10. Click Apply
  11. Click OK
  12. Close the Startup window

The Killer Control Center will now run at startup, in the background, on your next restart  If you have other applications loaded, it should run without stealing focus, but it will still load as a full-size window. You can switch to that window and click the X to minimize it to the tray, or you can leave it maximized in the background for quick access to its user interface. Unfortunately, we have found that Windows does not allow UWD applications to load fully minimized to tray.

Prompts to Update Killer Control Center

2.4 

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. 

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 - https://www.killernetworking.com/killersupport/.
  • 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 try clean installing the Killer Control Center. You can find instructions for that here - https://www.killernetworking.com/driver-downloads/kb/faq/105-clean-install-the-killer-control-center

Internet Problems With New Computers

2.8 

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. 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.

VPNs and Chrome

 

VPNs and Chrome

Users may notice network interruptions when using Chrome on VPNs. This may not be related to your networking adapter, but rather an issue with Chrome and your computer's Internet settings. The resolution is to stop your computer from automatically detecting proxy settings, which are unnecessary unless you are using a proxy, and can be disruptive when using Chrome with a VPN. Here are the steps:

  1. Click Start
  2. Type Internet Options and press Enter or click "Internet Options"
  3. Click the Connections tab
  4. Click the LAN Settings button
  5. Make sure the box beside Automatically detect settings is NOT checked

You can now close any remaining open windows. 

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 clean installing the latest Killer Control Center by following this guide - https://www.killernetworking.com/killersupport/driver-downloads/kb/faq/105-clean-install-the-killer-control-center. 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. 
  • If you still have issues with your VPN connecting after clean installing the latest Killer Control Center, please try restarting your machine, and then uninstall and reinstall your VPN software.
  • If that does not resolve the issue, try using the Windows built-in Network Reset feature by clicking Start, and typing Network Reset. Then, click Network Reset and follow the prompts. You will likely need to reinstall your VPN software again after doing this. 
  • If the Network Reset does not resolve the issue with your VPN connecting, please try resetting  your network equipment and your network stack by following the guides here - https://www.killernetworking.com/killersupport/driver-downloads/kb/faq/93-resetting-network-devices-and-network-stack.
  • If that does not resolve the problem, please contact us using this form - https://www.killernetworking.com/killersupport/driver-downloads/contact. Please include the requested diagnostic. Also, in the body of your ticket request, please include these details, if possible:
    • Link to VPN client software, if publicly available
    • On what type of server is your VPN server running (Linux, Windows Server, etc)? This would be the machine to which you connect when  you connect your VPN, not your own machine.
    • VPN Type (PPTP, L2TP/IPsec, etc)
    • Authentication Type
    • Encryption Type
    • Any other specific details that either you or your IT team or manager deems pertinent for us to troubleshoot a VPN connectivity issue. 

Service Not Running

1.7 

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. We recommend following our clean install guide here - https://www.killernetworking.com/killersupport/driver-downloads/kb/faq/105-clean-install-the-killer-control-center.

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 temporarily 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 https://www.killernetworking.com/killersupport/driver-downloads/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 https://www.killernetworking.com/killersupport/driver-downloads/contact so that we may assist you further.

Bandwidth Test Error in Killer Control Center

2.0 

Bandwidth Test Error in Killer Control Center

Users may notice errors with the built-in bandwidth test. This may be caused by a few things:

  • Our bandwidth test uses a software API to connect to one of many potential speed test servers. Some time ago, that API changed the way it accepted connections. Old versions of the Killer Control Center may be trying to connect the old way. The fix is to update the Killer Control Center. We suggest using our clean install guide here - https://www.killernetworking.com/killersupport/driver-downloads/kb/faq/105-clean-install-the-killer-control-center.
  • Sometimes the nearest server to you may be down, resulting in an error. This will usually clear itself quickly as either the server will come back up, or the service will reroute the request. In the meantime, you can use a service like http://www.speedtest.net to test your speed, then input the upload and download values manually. There is no disadvantage to setting your speeds this way. 
  • If you have an antivirus or firewall application, it may be blocking the speedtest applet with an outgoing blocking rule. You may need to add an outgoing exception for the applet speedtest.exe in your antivirus or firewall application. You can find speedtest.exe in C:\Program Files\Killer Networking\Killer Control Center if you installed the Killer Control Center in the default location. 

Problems With 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, found here - https://www.killernetworking.com/killersupport/driver-downloads. 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 guide for the Killer Control Center, found 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 for the Killer Network Manager was in April 2017.

Removing The Killer Control Center

5.0 

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 - https://www.killernetworking.com/killersupport/driver-downloads/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 easily switch to a driver-only installation by following these steps:

  1. Download our driver-only installer - https://www.killernetworking.com/killersupport/category/other-downloads
  2. Download our Killer Software Uninstaller tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe
  3. Run the Killer Software Uninstaller tool.
  4. Choose Remove Killer Software. It will say RESTART REQUIRED when it is finished. Don't restart just yet!
  5. Click Disable Killer From Windows Update. This will install a "stub" driver that emulates an updated version of the Killer Control Center, so that any updates pushed by your machine or motherboard manufacturer, through Windows Update, will not install as they will perceive the blocking driver as a later version of the Killer Control Center.
  6. Restart your machine by clicking Start > Power > Restart
  7. You may be tempted to stop here, as Windows will install drivers for most of our products. However, most of the drivers installed by Windows are older, problematic drivers, which is why we suggest installing the latest device drivers by running the driver-only installer. This will install only the device drivers, nothing else.
  8. Restart your machine if the installer calls for it. 
  9. You should now have only the latest device drivers installed, without any performance suite. You may want to bookmark this page - https://www.killernetworking.com/killersupport/category/other-downloads - for future driver updates. 

 

Network Column in Windows Task Manager Not Working

2.0 

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

1.7 

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 Killer Control Center here -  https://www.killernetworking.com/killersupport/driver-downloads.

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

 

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. I

If you are experiencing memory leaks, we highly suggest clean installing the latest Killer Control Center by following these 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, 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. 

If you continue to experience memory leaks after updating to the latest Killer Control Center and device drivers, please contact us using this form - https://www.killernetworking.com/killersupport/driver-downloads/contact

Please include:

  • The diagnostic requested by the form, with the latest Killer Control Center installed, after you have confirmed that the memory leak still exists
  • Some explanation as to how you reached the conclusion that our drivers or software are causing the issues.
  • Links to any relevant screenshots or logs that show our drivers or software using an inflated amount of memory.
  • Any troubleshooting steps that you have already tried.

DNS_PROBE_FINISHED_NO_INTERNET Error

 

DNS_PROBE_FINISHED_NO_INTERNET Error

Some users may encounter a DNS_PROBE_FINISHED_NO_INTERNET error when browsing. This seems to happen most often with Google Chrome, but users have reported the error with other browsers, as well. This error is generally not related to or caused by your Killer Networking drivers, or the Killer Control Center. However, using very outdated drivers could potentially cause this problem, so updating to the latest drivers is a good idea. Following are some troubleshooting steps to resolve this issue:

  • Clean install to the latest Killer Control Center (click me for a guide)..
  • Restart your network devices and network stack (click me for a guide). The vast majority of users with this issue report that this resolves the problem for them. 
  • Make sure your browsers are not trying to use a proxy. The following settings affect Chrome, and some other browsers in Windows. 
    • Click Start
    • Type Internet Options and press Enter
    • Click the Connections tab
    • Click LAN Settings
    • Unless you are using a proxy (if you don't know, you probably aren't), none of these boxes should be checked, not even Automatically detect settings. Uncheck them all.
    • Click OK, then OK on the previous window, then test to see if the problem is solved.
  • Scan your system for Malware. Malwarebytes is a good, free anti-Malware tool that may find things that the built-in Windows Defender did not catch. 
  • If you are using an antivirus application other than Windows Defender, some have noted that this issue was caused by antivirus applications. Try completely uninstalling the antivirus application to see if that resolves the issue. Many times, even if this does resolve the issue, you can restart your computer and reinstall the antivirus application, and the issue will not return. Unfortunately, disabling these applications will not do the same thing, as they will continue to manipulate network traffic when disabled. They must be uninstalled. 
  • Completely uninstall and reinstall your network drivers, deleting the drivers stored in your driver cache and the files in your temp folder (click me for a guide). 
  • Clear the cache for your browser(s). Please note that this will delete some saved logins if those logins are not saved by the browser's login saving feature, and are instead just "remembered." You will need to refer to your browser for further details, if you are unsure.
  • Specify your DNS servers. This shouldn't be necessary, but some users have reported that doing so has solved this issue. To do this:
    • Right-click Start
    • Click Network Connections
    • Click Chance Adapter Options
    • Right-click the adapter that you are using for Internet and click Properties
    • Double-click Internet Protocol Version 4
    • Click the button for Use the following DNS server addresses, which should open up the number fields below. In them, type the addresses for Google's free DNS servers:
      • 8.8.8.8
      • 8.8.4.4
    • Click OK and then click OK again, then close the rest of the open windows and test. 

If you know of another solution to this issue, aside from resetting Windows, please send us an email and let us know at killersupport@rivetnetworks.com!
