Hi, I have recently just upgraded my internet to 100mbs from 70 mbs. There is zero difference to my download speed on wifi, remaining at 40 - 49mbs. We have the virgin media super hub and a belkin n600 router. If I Ethernet to the router I get 92mbs. What is causing the loss of speed on wifi and why did it not increase at all despite having another 30mb coming in? I am not hugely tech savvy so plain English please. Is there a setting that is limiting the output? Any help appreciated.
