I have a Qualcom Atheros AR9485 Wireless Network Adapter
on a Samsung laptop and running 14.04.
My laptop can see the wireless network, but it keeps asking for the password and I can't connect. I know for a fact that it's not my router because my phone can connect and so can my tablet.
I have Wireless N only running on 20 MHz.
