in the past few days my router started fucking up. i've got 3 PC's hooked up to it, and a cable modem connection. its ran fine for years, but now computers going through it can't browse the internet, or do almost anything online
i know it's not a problem with the connecting cables, since i can log on XFire and join multiplayer games with it. but most other programs won't work, AIM, in-game server browsers, etc
hooking the modem directly to a computer works, so my guess it's something in the router settings, since i doubt all the computers got fucked up in exactly the same way at exactly the same time
looking through the settings though, i can't really find anything wrong. i can ping the router, and ping any other computer hooked up to it. but i can't ping anything external. and setting a computer to DMZ mode didn't work either, so i'm pretty sure its not any of the firewall/filter settings
