Solved 24H2 installed -- WIFI not connectable -- Cannot connect to this network ( now fixed)

Hi folks
kept getting "Cannot connect to this network" messages after updating to 24H2.

Fixed by uninstalling the realtek wifi driver and re-installing the old one from my 23H2 installation -- all working properly now. Symptom was it couldn't detect any 2.4 Ghz wifi signals and automatically started using the 802.11d protocol -- even when disabled. Also the wireless mode was set to Auto and couldn't be changed on the properties for the device. With the previous driver I could select 802.11 a/n as the protocol (on the old ISP modem using here at the temporary address I'm using even 802.11a/c/n wouldn't work). Prompted for Wifi password and all working properly.

Windows release:



Wifi NIC:



properties (use the advanced settings)



(Disabled the 802.11d option, and set wireless mode to 802.11a/n - these options weren't available in driver after 24H2 update or would revert bck to enabled / auto etc).

Cheers
