I have gigabit service. On my cell phone it will speed test on wifi at over 400. On my desktop with has 10/100 and wireless b/g/n it will speed test the wifi at apx 45 which seems right... and wired at about 70.
SO..... I got a USB 3.0 gigabit ethernet adapter. However it still won't go above 85 for a down speed I get 37 for upload. I checked and it is plugged into a 3.0 port and I manually changed it to the gigabit from "auto". Is there possibly a powersaving setting or something in the gateway that is limiting me?
