Killer Control Center Errors After Update
Some users may experience errors with the Killer Control Center after updating to the latest version. This usually occurs when updating without uninstalling the old version first. While this is normally not a problem, we have noted that some users are encountering problems where:
- The Killer Control Center will not open
- The Killer Control Center causes GDI Exception Errors
- The Killer Control Center causes a "NavBar" error.
- Some specific websites are not accessible, while most websites are accessible.
The solution to these issues is to perform a clean install of the latest Killer Control Center by following these steps:
- Make sure you have a copy of the latest installer handy - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
- If you are encountering the issue where some websites are not accessible while most websites are accessible, download the Killer Remover - https://www.killernetworking.com/support/KillerRemover_v22.214.171.124.exe
- Right-click Start, click Apps and Features, and then find every "Killer" application listed, click, and click Uninstall. This includes any and all "Killer Performance Driver Suite" and any variation. Make sure you are also uninstalling the Killer Network Manager, as the Killer Network Manager is not meant to be run with the Killer Control Center. The Killer Control Center replaces the Killer Network Manager.
- Restart your machine by clicking Start > Power > Restart
- If you downloaded the Killer Remover in Step 2, run it now. It will have you restart again once it is finished running.
- Once your machine has booted back up, access the temp directory by clicking Start and typing %temp% and pressing Enter.
- Delete the contents of this folder. These are temporary files that are meant to be deleted from time to time - you cannot harm anything by deleting all of these files. You may not be able to delete some of these files. It is okay to "Skip All" for these files.
- Double-click the installer for the latest Killer Control Center. and follow the prompts to complete install.
- Test to see if the issue is resolved.
If you continue to experiencing issues, please contact us at firstname.lastname@example.org.

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 follow these steps:
- Right-click Start
- Click Apps and Features
- Find "Killer Performance Driver Suite" or any variation or variations, and uninstall it or them, restarting when required.
- 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.
- 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.
- 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.
- 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.
- Make sure your BIOS and chipset drivers, at least, are up to date from your machine manufacturer's support site.
- Make sure Windows 10 is fully up to date. To do this:
- Click Start
- Type Windows Update and press Enter
- Click Check for Updates
- Let your computer install whatever updates it finds.
- Once it is finished, restart your machine by clicking Start > Power > Restart, even if it has not asked you to do so.
- Repeat steps A through E until your machine finds no updates just after restarting.
- 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.
- 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.
- 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.
- 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 issues with your Killer adapters, please do not hesitate to contact us directly!

Router or Modem Issues With Killer 1535
This article is intended to cover all issues that affect any access point, be it a router or modem, that occur when the Killer Wireless-AC 1535 connects or is connected.
The 1535 is a cutting edge Wireless-AC device with MU-MIMO and Transmit Beamforming technology and, as such, not all access points have firmware already installed that is able to handle the connection. Problems that some of our users have reported include:
- Access point restarts or crashes upon connection, requiring restart
- Access point restarts or crashes after being connected for some time, requiring restart
- Access point slows dramatically
- Access point randomly disconnects all connected devices
The fix for this issue will depend on your personal situation.
- You Own the Access Point
- The Access Point is Owned by Your ISP
- You Have No Control Over The Access Point and Need to Handle The Issue With Drivers
You Own the Access Point
In this case, you are connecting to a device, such as a router, that you own, which is then connected to another device, such as a modem, which is owned by your Internet Service Provider (ISP). If the device in question is a modem, please be sure that, even if you own the device, your ISP supports any firmware that you flash onto the modem. Most ISPs maintain a list of accepted firmware versions for each device online.
In many such situations, you can update the firmware of your device to resolve this issue. You should first try to update the firmware through the router's interface, if possible. If that is not a feature of that router, or if that does not solve the issue, check for the latest firmware from the official support page of your router. If the problem is still not resolved, then see if your router is listed below. Listed below are the routers whose model numbers that we are aware of have issues, along with the location of the updated firmware that the router manufacturer has made available to address the issue:
- Netgear WNDR5400 v3 - - Support rep PMing individuals beta firmware on a user-by-user basis. We are unaware of this particular version of the firmware being hosted openly anywhere.
- TP-Link TL-WR841N V11
- TP-Link Archer C7 AC1750 V2/V3
- TP-Link Archer D7 V1
- TP-Link MR6400 V1
If you own a different model than the one listed above, and updating to the latest firmware that is available from the support page of your router's manufacturer, we suggest contacting the support for your router, we suggest first updating to the latest Killer Control Center, found here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If that does not solve the issue, the next step would be to contact the support for your device and advise them of the steps that you have taken, and ask if they have a beta firmware available. At the same time, please contact our support, as well, using this form - http://www.killernetworking.com/about/contact.
The Access Point is Owned By Your ISP
In this case, it is very possible that the device is running a very old firmware version. Most ISPs only update the firmware at the customer's request, or when it is absolutely necessary in order for the device to continue working on their network, and many ISPs use very old equipment. If you are connecting directly to an ISP owned device, and you are experiencing these issues, then your best bet would be to contact your ISP's support, and request that they update the firmware on the modem. This is usually a simple thing for them to do. If you are unable to resolve this by asking your ISP to update the firmware on the device, please let us know by contacting us here - http://www.killernetworking.com/about/contact - so that we may document the model of the access point that is not fully compatible with our device. In most cases, however, it is due to the age of the device, and a bug in its firmware. If asked, your ISP may be willing to change you to a different model of access point. You might also be able to provide your own access point (sometimes saving a monthly rental fee in the process), or buy your own router to plug into their modem, then use your router as the access point. If you decide to buy your own modem, most ISPs maintain a list of modems that work with their service. If you use multiple devices at the same time on the same access point, there is a good chance that you will see a boost in performance on all devices by providing your own modem.
Addressing the Isssue with Drivers
There are some discussion threads where we have commented, linking to specific drivers on our site, where those drivers have now been moved, causing 404 errors, or redirections to this page. Those drivers were links to .INF drivers that could be installed using the Device Manager, to address specific access points crashing when the 1535 would connect to them. These posts and links were created before we had driver-only installers hosted on our website, and were generally just the latest driver-only file that we had available at that moment, as the problem was believed to be cause by the performance suite at the time. You can now download the latest driver-only installer here - http://www.killernetworking.com/driver-downloads/category/other-downloads. However, this will not always solve the issue, as the issue is sometimes not the performance suite, but that of buggy firmware with the access point. If you wish to try and address the issue by using a driver-only install, you will need to download the driver-only installer, then uninstall all "Killer" entries in your Programs and Features menu, restart your machine, then install the driver-only package. This will remove all Killer network management capability.
We have had some reports of users who were only able to keep their routers stable with only one very specific driver version - usually some Windows 8.1 driver used on a Windows 10 machine. In those cases, we will do our best to locate a copy of that specific version for you but, unfortunately for those cases, Windows Update will often update those drivers anyway, and that is completely out of our control. There are some guides out there on how to prevent Windows Update from updating your device drivers, but we have neither tested nor endorse any particular method of doing so, and we cannot say what the repercussions may be.
