Issues With Internet and General Network Connectivity

The following is a basic troubleshooting guide for all issues with the Internet and basic network connectivity. If you are experiencing problems with your Internet or network connection, please try the following, as these steps will more than likely solve the issue quickly and efficiently with a minimum of time spent on your part.

  1. Update your drivers.
    1. You can find the latest Killer Control Center, with the latest drivers, here for all Killer Wireless-n/a/ac (1435, 1535, 1525, 1550) and currently supported Ethernet adapters (E2200, E2400, E2500, E3000) with current versions of Windows 10 (1803+):
        And here for all Killer Wireless-N adapters (1102, 1103, 1202), regardless of operating system version. This version is also for Windows 7 and Windows 8.1:
        • Once you have the latest installer, right-click Start, click Apps and Features, then uninstall all “Killer Drivers” and “Killer Suite” applications, and any variations.
        • Restart your computer by clicking Start > Power > Restart. Note that using the power button on your machine most likely activates sleep mode, and does not shut the computer down, so it does not work for this purpose.
        • Once the computer has restarted, install the latest suite by double-clicking the installer package that you downloaded earlier.
        • Restart the machine once more once the installer has finished.
        • Test to see if the problem is resolved. Continue reading if not.
      • Reset all of your networking equipment by doing the following. Please note that while you may have done this previously, or may have reset some of your networking equipment, it is worth your time to reset all of it, in the proper order, to make sure that this straightforward, and very useful troubleshooting process has been ruled out. If you do not have access to your access point, skip
        1. Shut down your computer by clicking Start > Power > Shut Down.
        2. Locate your modem and note the lights on your modem when it is normal and ready. There may be a “Ready” or “Online” light. Taking a picture with a phone is a good tactic so that you know when it’s ready to go.
        3. Trace the Ethernet cord (not the screw-in coaxial cable or the power cord, but the one with a clip) to the next device to determine if you have a router.
        4. Unplug the power cord (either from the back of the device or from the wall, whichever is more comfortable) of your modem, router, and any switches or hubs,  between your computer and the modem, as well as any wireless boosters, powerline adapters, or access points, and leave them all unplugged for now.
        5. Plug in your modem.
        6. Wait until your modem’s lights show normal operation again.
        7. Plug in your router, if you have one, and give it about five minutes to boot. Routers typically have no external means of telling if they are ready, but they should be ready after a five-minute wait.
        8. Plug in anything else between your computer and the modem
        9. Power on your computer.
        10. Test to see if the issue is resolved. Continue reading if not.
      • Reset the network stack on your machine by doing the following. Please note that, even if you have already tried some of these commands, others on this list may be necessary to reset your network stack properly.
        1. In the search box on the taskbar (click Start), type command prompt, right-click the command prompt result and then select Run as administrator and confirm.
        2. Type netsh winsock reset and press Enter. (Decline restarting your machine until you have finished running all of the commands)
        3. Type netsh int ip reset and press Enter.
        4. Type ipconfig /release and press Enter.
        5. Type ipconfig /renew and press Enter.
        6. Type ipconfig /flushdns and press Enter.
        7. Restart your computer.
        8. Test to see if the issue is resolved.

      If you are still unable to resolve the issue, you need first to identify the actual problem — is the router having issues when the Killer adapter connects or is the Killer adapter having issues when it connects to your access point? If you have other devices that are also connected to the same access point, and those devices continue to work, uninterrupted, throughout your troubleshooting, then the issue is with the trouble machine alone. In that case, please feel free to contact us at the link below.

      However, if other devices are disconnecting when the trouble machine connects, then the issue may be with the router’s firmware. In that case, please click here for further troubleshooting.
