It has been a while since we posted any registry hacks but here is a quick and beneficial registry hack, enabling WIFI draft n support, if you have a HD2. Wireless draft N or 802.11n connection will significantly increase your raw data rate from about 54mbps to about 600mbps of course you need to have a wireless N router as well. If you have a wireless N router then you will see an increase in speed for sure and many people have confirmed that the hack works. Make the following registry change:
change the value of “11nModeDisable” from the default 1 to 0
