Can some one help....? I am fairly new to xbox and all its wonders, so was satisfied with my xbox live connection using xbox wireless adaptor to my sagem wireless router with sky BB on their 8mg package, i play very regularly.....( every night ) and as my multiplayer skills increased i noticed my players reaction and even movements were slower than some of the other players and started loosing connection in the lobby. Then last week the wire less adaptor failed so as a make do till i accuired another i used the net cable to the router, thats when i decided not to use the wireless again! a vast improvement in game play, not enough i also portforward and assigned a static ip address for use with the DMZ..... this is where my problem lies....... my router recognises the xbox as an attached item, but when i try connect test in dashboard it fails at x live...? telling me "connection fail due to insufficient MTU to connect to x live you must have at least an MTU value of 1364" but in my router settings the MTU is set at 1500bytes???? WHERE AM I GOING WRONG?
