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!

Hi,

The Windows Wireless LAN 802.11 Extensibility Framework provides an interface to Windows wireless security and connectivity features for the drivers of wireless network adapters.

Let’s try these methods and check if it fixes the issue.

Method 1: Run System Maintenance troubleshooter and check.

a) Press Windows and X key together and select Control Panel.

b) Click on Troubleshooting.

c) Click on View all option on the left side of the Windows.

d) Click on System Maintenance option.

e) Click on Next and follow the onscreen instructions to troubleshoot the issue.

Method 2: C heck the functionality in safe mode with networking.

Step 1: Start your computer in safe mode with networking and check the CPU usage.

Refer this link to start the computer in safe mode.

http://windows.microsoft.com/en-IN/windows-8/windows-startup-settings-including-safe-mode

If it works fine in safe mode with networking, let’s place the computer in a clean boot state.

Step 2: Perform clean boot.

Clean boot will help us identify if any third party applications or startup items are causing the issue.

To do this, follow steps from this link:

    Hi,

    it seems too simple to be true, but I disabled my network adapter and re-enabled it in the Network Connections window. I tried it ten minutes ago, so I cannot tell for sure it won't come back, but so far my cpu went back to normal.

    I tried that too. The only thing I had to do differently was Terminate the "Windows Wireless LAN 802.11 Extensibility Framework" process after I disabled the network adapter (because the process didn't slow down). It re-enabled itself after I turned the Wi-Fi back on. So far things have been good.

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

    Hi Mark,

    I would have you install latest version of network adapter drivers and check if it helps.

    You may also try installing all available Windows Updates including Optional Updates and see if it makes any difference.

    Hope it helps.
