Having the 6G working without the WPA3 password requirement runs it as an open network. You may be partially protected but you might give some thought to what an unknown user might be able to do using your network.
If the radio was visible, the new driver more than likely overwrote the Registry entry you modified for the 6 GHZ to be seen.. It might be best to put it back to the Password requirement and wait until Oct., if you have a system capable of Win 11.
