Windows 10: Update from MS: February 2, 2021—KB4598291 (OS Builds 19041.789 and 19042.789) Preview.
After this preview update my Wifi adapter - intel ac 8260 stopped to work: it fills event log with errors 5000. Upgrading driver to the lateset one from intel's site didn't get a relief. Only uninstalling this update solved the problem.
I'm not sure on which side is the problem, but put it here just in case, maybe intel devs will look at that.
zandr, Thank you for posting in the Intel® Communities Support.
Perfect, excellent, it is great to hear that the problem got fixed by replacing the Wireless card and now it is working properly.
Any other inquiries, do not hesitate to contact us again.
