I have a D-Link DI-604 router for computer internet use and xbox live... just recently the internet use for the computer has been very unreliable... I would open Mozilla, my homepage would load... then any other site I would try and go to would not work.. it says "Server not found" so I went to options and connection settings, changed it from Direct Connect to Auto Detect Proxy Settings and it would then load the page. If I tryed to go to yet another page or back to my homepage it would say "Server Not Found" again............. Does anyone have any ideas?? Could it be my Ethernet Cords?? Also the connection for Xbox live works perfectly with no trouble whatsoever.
