I know i've asked this question alot already, but nobody seems to be able to give me a clear-cut solution.
After about 30 seconds - 2 minutes after signing into xbox live, i recieve a "disconnected from messenger" message followed closely by a "disconnected from xbox live" message.
I think i narrowed down the problem to my modem because whenever i lose connection and it times out, the lights on my modem will flash irregularly . I know it's not my router because the status indicator light will still read green across the board and i'm still able to wirelessly with all my devices even though the internet has been dropped/timed-out. This problem only happens with my 360 and none of my other devices. The only way i know how the dropped internet connection (at least temporarily) is to unplug my modem and plug it back in and wait till a four lights come on. But in the end, i'm still going to disconnect, so whats the point?
Are there any settings on my modem that i can change so this disconnecting problem stops?
I've tried everything. I've called xbox support, but i for the life of me can't get pass the automated voice, but on the rare occasions i do. I for the life of me can't understand the mans accent. I've called my ISP (the supplied the modem), but they don't know when it comes to networking with xbox live. I've tried plugging my 360 directly into the modem via an ethernet cable, but that didn't work either. I forwarded every port combination on the modem everyone told to forward, but that didn't work either. I've also tried putting my 360 into a DMZ, but that made my NAT type strict and i couldn;t connect to any of my friends and i still disconnected after a while.
