For the past month, I have been enjoying my Xbox Live and internet together (Xbox is wired to the router, desktop and laptop are wireless). For some reason, on July 16th, I could no longer get videos to play on Xbox live, using Xbox Video, Amazon Instant Video, Halo Waypoint, Hulu Plus, etc. On July 15th, videos worked fine. On the 16th, they didn't. If I bypass the router and connect the Xbox to the modem, things work fine, but I can't surf the interwebs while this is happening. If the kids want to watch a show, I can't be online, and vice versa.
I have a DIR-826L with firmware 1.01 (whatever came loaded on it), after the problem started, I tried an IP address reserved for the xbox, ports forwarded (uPnP didn't work anymore), manual settings on the Xbox to match what the router is set for, deleted system cache, deleted & redownloaded profile, etc., etc., etc. Nothing is working.
I'm just at a loss as to why things would work fine one night and not the next when no settings changed, nothing was done except turn the xbox off and then on the next day. No power surge to harm the router (plugged into a 2600J spike strip anyway). Why does it work fine when the router is bypassed? What am I missing? I'm seriously considering returning this thing and getting a wireless Netgear -- as my previous wired Netgear router never had problems -- unless I can get this thing resolved.
