Wi-Fi Power Settings

Unfortunately, Wi-Fi drops and performance problems are all too frequent with Windows, and Microsoft has addressed the issue, essentially placing the blame on the wireless access points. You can read about that here – https://support.microsoft.com/en-us/help/928152/you-may-experience-connectivity-issues-or-performance-issues-when-you – but, to summarize, the default power plan is not ideal for Wi-Fi, and Microsoft’s suggestion is to maximize power going to the Wi-Fi adapter and remove the ability for Windows to turn the adapter off to save power.
With some users, this has fixed all of their issues. With others, it has not helped at all. However, if you’re experiencing problems like Wi-Fi drops, slowdowns, or latency, it’s worth adjusting.
Doing this can potentially cause a slightly shorter battery life. However, this is an excellent way to troubleshoot whether the issue is related to the power saving features of your machine and/or access point. You may find that making these changes makes no noticeable change in your machine’s battery life. On the other hand, you may see that there is a noticeable effect, in which case you can switch the power profile back.

To check your power settings:

  1. Right-click Start
  2. Click Power Options
  3. Click Additional Power Options on the right.
  4. Click Change Plan Options on the currently selected power plan
  5. Click Change Advanced Power Settings
  6. Click Wireless Adapter Settings
  7. Under “Power Saving Mode” change “Setting” to Maximum Performance on both “On battery” and “Plugged in”
  8. Click Okay then Save Changes.
  9. Close all Power Options windows
  10. Right-click your Start Button and click Device Manager
  11. Find the Network Adapters heading and double-click it.
  12. Find your Killer Wireless Adapter and double-click it.
  13. Click the Power Management tab.
  14. Make sure the box for Allow the computer to turn off this device to save power is not checked.
  15. Click OK
  16. If you are missing any of these options, then that means your machine’s manufacturer has disabled them in the registry. Many of our users have had luck using the method described here. Please note that the registry changes made in these guides make no permanent changes to your system other than to make the settings available for you to change. The registry files do not make the changes – they only add back the setting options that are present in standard Windows 10 installs, but have been removed in some.
