ok first of all i dont know in what forum this should be in. my first question is, i have xbox live and i connect through a router. my router has 3 cables, one to the computer, one to my xbox, and one to the modem. my xbox live was working a while ago and i didnt use if for a while. i troubleshoot my xbox and it says "make sure your MTU (maximum transmission unit) for my router is 1365 or higher. does anyone know how to change/view that. it was working a few months ago and all i did was add another computer into the router (it now has 4 cords). it also says make sure my connection sharing is enabled. does anyone know hoe to enable connection sharing?. please help. thanks
