"If I force my router into wifi-G mode, all of my devices connect at around 50Mbps too. Connnection speed only degrades over distance."
Yes I agree.
I am not disagreeing with you.
What I am saying is that my N devices connect at 144Mbps, G devices connect at 54Mbps.
On speedtest.net I get 50Mbps on N devices EVEN WITH g devices connected.
I am NOT saying that my N devices connect to the router at 50Mbps. They connect at 144Mbps even with g devices connected. The N devices get a speedtest at www.speedtest.net
of around 50Mbps
Ie in the real world when downloading I see no difference.
