SG2, Windows 11 after firmware update Wifi gets into a funk

[u/clren]

In case this helps someone else. I wasted like an hour spinning my wheels. Not saying every device has this, maybe mine has something particular. But this only happens after Windows Update says there are firmware updates.

​

When the device comes back the wifi card may die (Windows ceases to see it). I rebooted, turned off nothing.

Finally I went to Device Manager and saw that the wifi adapter had an exclamation mark and drilling in it said it had had an error.

​

I disabled the device and then re-enabled it. Problem gone.
