Here is a great tweak that speeds up your Wi-Fi.. It works by enabling the “g mode” of your device’s WLAN card (disabled by default on most devices). This hack has proven to improve Wi-Fi speeds by 3 times..
Iinstall the attached .CAB to the device, then soft reset. It will change the value of dot11SupportedRateMaskG from the default 4 (1 in some cases) to 8 inside HKEY_LOCAL_MACHINE\COMM\TNETWLN1\PARMS.
Note: Some devices don't have that structure in the registry. If it's your case, our cab will create it automatically.
I do not take credit for the creation of this.. I merely happened to find this at the site linked above and thought to post it here..
