Tried on Surface Pro2 WIFI adapter:'

Found a fix to slow SP2 Wifi Link Speed (self.Surface)

A while back, I was having an issue with my SP2 only connecting at 11Mbps or 5Mbps to my wifi. Awful.
Found a solution. Flipped the 2.4GhzAutoUse40MHz key from '0' to '1' in the registry, and I'm now cruising at >200Mbps link speed.
1) Open device manager, and find the wifi adapter.
2) Open the Details page, and get the Driver ID. It'll probably be something like {4d36e972-e325-11ce-bfc1-08002be10318}\0003
3) Open regedit and go to HKLM\SYSTEM\ControlSet001\Control\Class{4d36e972-e325-11ce-bfc1-08002be10318}\0003
4) Double check that you're in the right key by looking at the DriverDesc value.
5) Change 2.4GHzAutoUse40MHz from '0' to '1'.
6) Reboot
