Have installed this adapter on Windows 8.1, latest drivers etc, old network card disabled. Detects all wifi networks the old card did except the router network. It can connect to phone hotspots OK. Old card detecting router wifi network, connecting on 2.4Ghz to the router when re-enabled. Have tried everything (reinstalling software, re-booting, changing router settings (security/channel etc..) to no avail. WPS doesn't work, I assume as it isn't seeing the wifi network in the first place (inssider software shows all the wfi networks available thru each adapter and the router wifi isn't on the adapter list).
Any ideas, please? Am running out of ideas/patience.
