Since installing the PCIe card to my Lenovo dektop PC (Win11 Pro 64) over the last 2 weeks, it has dropped out, so I have had to revert to my Ethernet cable connection.  This has happened twice after working very well.  I have re-seated the PCIe card twice (just in case that's the problem), but at the moment I'm on Ethernet and it's not possible to see the WiFi card (or its firmware version).   Serial No. 22264T6004429.  If I could find it, I would try to update the driver from TP-Link, but Windows Update reports everything (including optional updates) and drivers are fully up to date.  What can I do now?
