Windows 10: Windows update or drivers killing wifi? Two computers with broken WIFI post updates.

I have two computers, a Dell XPS 15 9560 and a Precision 3561. Both of them are running Windows 11 Pro, and both are having the same issue:WIFI shows the available networks, I can select and try to connect to the network, and I get an error saying "Can't connect to this network."I originally thought it was a driver issue, but rolling back the driver, updating the driver, and trying an alternate version of the driver did not help. The computers have different wireless cards and are getting the same error. I also tried using a USB WIFI dongle, and that's also getting the same error.I rebuilt bot

Do windows updates slow down the computer?

Basically you might as well have the latest stable drivers on a Opticsl disk or usb drive and then updates thst dont bork the os, install updates, then dtivers and leave the system unplugged from ethernet/wifi then set parameters to prevent windows from updating automatically, save a list of settings you adjudted judt incase sn os update resets it to default etc.

W10 sounds more like a pita than it's worth to install...
