|Router basically splits your internet between multiple computers. Each computer is assigned an internal ip adress through dhcp. The reason that you cannot access the xbl network is becuase of your ports not being fowarded.|
The following ports must be open for full connection.
If you try going onto your computer and typing http://192.168.0.1
and if you get a username and password prompt use root and password RM60008
see if you can log into the modem thsi way. btw if non of the ip addresses above worked, go to cmd prompt and type ipconfig and w/e the gateway is, use it.
