Hello my mtu is sayin its failed
The MTU(Maximum Transmission Unit) failure when testing the xbox's connection can be do to a few things because Xbox live requires a minimum MTU setting of 1364. Sharing a slower internet connection with other PC's in the house can cause this error, The incorrect MTU setting in your routers programming can cause this error, The lack of firmware updates to your router can cause this error, an older modem from your service provider can cause this. Old or worn network cables and jacks and or RG(coax) cables if you have cable internet could cause this. Your Router or gateway could be incompatible with Xbox live.
Try a direct connection to the Xbox without a router and reset your modem before doing it. If your able to connect then you know its the router. If not you know its the modem or cables or jacks or even your Xbox if you havent tested it elsewhere.
You can tell your ISP to mail you the newest updated modem... sometimes they will have a guy just drop one off.
