Dell XPS M1730, Windows 7 Pro, Dell wireless 1505 Draft 80211n and generic USB 802,11ac. High end Linksys router with numerous devices connected. Recently tested 3 old laptops (running XP, 7, 10) with no wireless issues. Can connect ethernet. Can enable both wireless devices. Always get "Not connected - No connections are available" Have spent a lot of time on this but will do whatever you suggest.
