i am a xbox live user and have been connected to it fine for a week or 2 since buyin a year membership. but today i tried loggin on and keeps saying my mtu is no passing. i connect my xbox using a ethernet port to my pc then a wireless adaptor to my zoom adsl x6 wireless router. how can i change the mtu setting or change the connection back somehow to connect it correctly. (i have bridged the connection form my pc to my router to my xbox). please help me, thanks.
