I have a virgin superhub 2ac downstairs and on 100Mb and getting upgraded to 150Mb soon, im currently on a wifi adapter on the desktop upstairs and it can fluctuate alot but rarely have I seen it reach even 90Mbits on the 5ghz network. So when i get upgraded to 150Mbps do you think a better option would be to get a powerline adapter to reach the closer advertised speeds. I get between 30-70 on average on the 5ghz network.
