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!

Refer this link to start the computer in safe mode.

    I can't believe it either! 

    Control Panel\All Control Panel Items\Network and Sharing Center

    Disable/Re-Enable - CPU went from 25% to 2% straight away. 

    And most importantly, my laptop stopped whirring like it was trying to cool down a jet engine:-) Great answer, and thanks for posting it!

    Disabling and enabling the network adapter helped also with Windows 10.
