I'd really like my videos to not lag when I link my PC to my 360 to play them, so I need to reconfigure my wireless network. Right now it's telling me that it's at 802.11g, and for maximum performance, should be 802.11a. Soooo if anybody knows how to go about changing it, please let me know.
Go into your router. It's probably 192.168.1.1. Type that into firefox and find something that says "wireless configuration".
To check your router's IP:
Start > Run > cmd > ipconfig > Default Gateway
I didn't know the 360's wireless dongle was 802.11a compatible...
