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 have recently updated to Killer Control Center version 1.5.1618. Using this guide - http://www.killernetworking.com/driver-downloads/kb/faq/58-clean-install-any-driver - to completely uninstall and reinstall the Killer Control Center and the drivers for your Killer network adapter should solve the issue. 
  • You are not connected to the Internet. Connecting to the Internet with your Killer network adapter should clear this error. 
  • 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 connecting to the Internet using a network adapter other than a Killer product. Our performance suites only work when connecting to the Internet with our products. Be sure that you are connecting to the Internet using the Killer network adapter. 
  • You are using an incorrect device driver. Updating to the latest suite should resolve that issue. You can find the latest Killer Control Center here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If you have manually installed a device driver that was not provided by Killer Networking, you may need to manually uninstall that driver first, deleting it from your driver cache, before you install the latest suite. 

Please reach out to support, using the link below, if you are unable to solve the issue using the above information. 

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.

Issues When Updating or Installing Killer Control Center

 

Issues When Updating or Installing Killer Control Center

Users may encounter errors when installing or updating the Killer Control Center. 

If you encounter any problems, please select from the following options:

 

 

The Killer Control Center Cannot Automatically Update

 If the installer cannot automatically update, you might see an error, such as, but not limited to, this one:

Killer Performance Driver Suite Cannot Be Installed With

In this case, you will need to manually uninstall the previous versions. First, however, you will want to download the latest installer and have it handy. Once you have the installer ready to go, right-click Start, click Apps and Features, then find every entry that has "Killer" in it, including "Killer Drivers" and/or "Killer Performance Suite, or any variation, and uninstall them. After they have uninstalled, restart your machine, then install the latest suite.

 

Previous Killer Applications or Drivers Cannot Be Uninstalled
OR
There Are No Killer Applications or Drivers in The Apps and Features Menu But the Killer Control Center Will Not Install

If you encounter an issue where the old "Killer Suite" or "Killer Drivers" cannot be uninstalled, and they remain stuck in your Apps and Features menu, or they appear to be removed, but the latest Killer Control Center appears to attempt to install, then roll back, then there are a few ways to address this. Even if you can no longer see the old applications in your Apps and Features menu, it is very likely that they are still there, and that they are the problem. For very old previous installs, especially those that may be broken by updates from Windows 7 to Windows 10, we have developed a tool that can remove the old installs. Here is a step-by-step guide on downloading and using the tool. Use this as your first step in troubleshooting a broken older install:

  1. Download the Killer Remover from here - http://www.killernetworking.com/support/KillerRemover_v1.0.0.1.exe
  2. Right-click Start and click Apps and Features.
  3. Uninstall all "Killer" suites and drivers that will uninstall from this menu. 
  4. Close the Apps and Features menu and double-click the Killer Remover.
  5. Once it is finished, it will prompt you to restart your machine. Restart your machine, and check to see if the stuck item is removed from the Apps and Features menu

 

The Application is Still Stuck or The Latest Package Still Cannot Install After I Have Run the Killer Remover

The Microsoft Installer is probably encountering an error from which it cannot recover. Sometimes, you will get an error, such as "The feature you are trying to use is on a network resource that is unavailable..." or some other seemingly unrelated error, or the installer may fail with no error given other than it could not complete. Luckily, Microsoft has a tool to fix this issue, and you can find our detailed, step-by-step guide on how to find and use Microsoft's tool for fixing problems that block programs from being installed or removed- http://www.killernetworking.com/driver-downloads/kb/faq/34-error-2753-xtendsoftapservice. Make sure you choose "Uninstalling" even if you are trying to ultimately install the latest suite, as the problem is that you need to remove the remaining parts of the old software, even if they do not appear in  your Apps and Features menu. 

If you still have issues with the Killer Control Center's installer, or uninstalling older versions of the suites, please contact support, and we will be happy to help. If the installer is failing, please run the installer one more time, and include the log that is generated in your temp folder. You can access your temp folder by pressing Windows Key + R, typing %TEMP%...

 

winkey r temp

...and pressing Enter.

From there, sort by Date, and attach the most recent MSI***.LOG to your support request. It should be dated at the time you last ran the installer.

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. 

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 - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. 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, download the latest Killer Control Center installation package, then uninstall all Killer products from your Apps and Features menu, which is accessible by right-clicking Start, then restart your computer, and double-click the new installation package to install the new Killer Control Center.

The old Killer Network Manager suite is still available for download here - http://www.killernetworking.com/driver-downloads/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.

Updating or Installing The Killer Control Center

You can find the latest Killer Control Center, as well as the latest drivers for your Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500, here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64.

The installer will automatically detect and install on any 64-bit version of Windows 7, 8.1, and Windows 10.

If you are using an older version of our suite, such as the Killer Network Manager, or you have not updated your network adapter drivers since your last Windows feature update (for example: Anniversary Update, Creator’s Update), then we suggest downloading the Killer Control Center, but uninstalling any application with the "Killer" name from your Apps and Features menu (accessible by right-clicking Start) and restarting your machine before installing the Killer Control Center.

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

 

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

 

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. 

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

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.
