it says on the xbox that:
"verify that the maximum transmissin unit (MTU) size on the router is set to 1365 or greater"
i use my modem and connect it to the xbox downstairs (my computers upstairs so i have to disconnect the modem to get online)
i really want to figure this out.
i have been on xbox live b4 on this modem and xbox, but that was in august. im trying to play halo 2 with my friend. if you can give me any help, i would greatly appreciate it.
