I am trying to connect to xbox live with my Motorola SB5120. I am running the ethernet wire straight from the modem to the 360. Then i go to test the connection. it says:
Xbox LIVE: Failed
Then it brings up a screen where it says there is a problem with my connection. I selected more info and it says to change the MTU settings on the router. or directly connect to the modem. I already AM connecting directly to the modem. I have tried this a lot of times, and it just wont work. Ive tried everything i could find on the support site and nothing worked. Can anybody help?
