Ooookay. It's been a very long day of playing around with my router. I have a Belkin wireless G+MIMO router, F5D9230-4, V. 5000, and a Motorola (Style: MSTATEA) modem. My ISP is Bellsouth/AT&T. I have had Live working since January through this router and internet, with it set on "dynamic." All of a sudden, I received an error message saying that my MTU was insufficient.. so I changed my router to PPPoE so that I could hopefully fix the issue, bridging my modem in the process. Now my xbox will find the network, but cannot connect to the internet. It keeps telling me to do the basic unplug the router and wait 30s fix, which does not work. I've gone through the xbox troubleshooter multiple times, but still no fix. Did a manual DNS, hoping that would fix it, as I had to to get my laptop to connect wirelessly to the network. Still no fix. UPnP is enabled, not sure if that affects this particular issue. I've been trying to reconnect my xbox for about 7 hours straight now, and I am unable to do it on my own. Any help would be greatly appreciated.
