Intel® Dual Band Wireless-AC 8260 SLOW since Feb. 2021 MS Update!

Jump to solution

My Dell Latitude e7470 used to be the fastest in a house full of Dell laptops (all w/ Intel NICS) when it came to internet speeds BUT since Microsoft's Feb. 2021 update, it is now painfully slow. Used to get 480 Mbps but now getting 80 Mbps downloads. 

Intel® Dual Band Wireless-AC 8260, Version: 20.70.19.1, Date: 9/15/2020

Tried previous versions of the driver and the latest version (above). 

Went to a previous Restore Point on in Win10 laptop. 

Nothing seems to resolve this issue. 

Appreciate recommendations!

I wound up rolling back to an earlier Restore Point prior to the big Microsoft Update and it is now working well again. So not the driver but something in the MS update that took me from 400 MB download to 80 MB. Have put the MS Updates on pause but hoping this gets sorted out since they include security updates that will be needed. Thanks
