Wi-Fi issues

[Snake Doctor]

When I am on wireless the best I can do is 5.0 mbps and that is a good performance. Does anyone have suggestions on how to increase the speed? If I hard wire to the docking station, I can get up to 48 mbps.

Also, my wife's Ipad will connect in areas my Surface will not. Any suggestions on how to correct this?

Thanks

Johnnie
