Windows Wireless LAN 802.11 Extensibility Framework using too much CPU power

Anonymous

Recently, my computer's been running significantly slower. A quick look at my task manager showed me that the "Windows Wireless LAN 802.11 Extensibility Framework" was using up 40+% of my processing power, and I have no idea why or how to reduce it. I'm fairly certain it's doing things it shouldn't be doing, but again, I have no idea what to do. Any help would be greatly appreciated!

    I too have this issue.

    This process keeps kicking in from time to time, randomly it seems, taking up a lot of CPU. Closing it in Task Manager does the trick. But how to stop it from happening again and again?

    (Win 8.1, Dell XPS 15, all the latest wifi card drivers, latest bios, all windows updates.)

    Thank you for the update, Jim.

    You may try installing the latest version of BIOS updates and check if it improves the performance more.

    Note: Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

    Please do not hesitate to contact us if you have further questions on Windows. We will be glad to assist you.

    I too have had this issue - even when connected to a wired network port.

    Hi,

    I have the same issue. windows wireless lan 802.11 extensibility framework taking up 20% of the processor and hence the fan is always running. I am using Windows 8.1 with all the latest updates. I don't think I have made any changes to the system recently. I have noticed that the laptop is running hot even when idle for the last couple of months but didn't investigate. Today I investigated and found that it is because that process is taking up 1 entire processor (My system is Quad core in HT so basically taking up 1 whole hyperthreaded core).

    Hi,

    I have exactly the same issue. The note from Russel describes my issue to the t. Did anyone have luck sorting this out.
