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:

    Same issue with same laptop.

    Disabled and re-enabled wireless adaptor to fix.

    Be good to get a solution rather than a workaround.

    Thanks, I updated the driver (Intel Dual Band Wireless-N 7260 on Vaio Pro), fan is quiet and will let you know if the problem starts up again.

    Now we are getting somewhere.  I have the Lenovo Yoga 2 Core i7 with the same Wireless-N 7260.

    The issue is intermittent.  I will have normally 7 hours of battery power.  When I notice heat/fan/bad power consumption (every 3 days or so without rebooting, rebooting "solves" it for a few days), I know it is time to reboot or kill the process.  

    I have version 17.0.1.5 of the driver, dated 3/12/2014.

    Version 17.0.3 is on the Lenovo site, but of course, Windows Update says the drive is "current".

    Wish Windows Update worked on device drivers ;-)
