adapter finding every wifi network but the one I want it to connect to
Hi,
I've installed the adapter on my windows 8.1 pc with the correct download. I had disabled my network card beforehand. The wifi list for the adapter shows all the wifi networks my old network card showed except for my router. The adapter connects successfully to phone hotspots. If I enable the wifi card again, the router is shown as well and I can connect without a problem. Using inssider I can see the network card is connecting via 2.4Ghz so it's not that the adapter is trying to connect to a 5Ghz network. The adapter obviously wont connect using wps as the network isn't in the available list.I have spent too many hours trying changing security, channels etc on the router but to no avail. The number of re-installations of the software, re-boots etc...
Please, could anyone point me in the right direction? Any help would be appreciated. I would really like to start using some of the fibre installation's real speed.
