...then it sounds like you need to replace the router, or did you change some settings on the router.. If nothing else, try turning OFF the computer, then turn OFF the router, then turn OFF the modem.. If there is no on/off switch, unplug them all. Once that's done, wait ten minutes, then turn ON the modem, wait 2 minutes to let it reinitialize, then turn ON the router, wait 2 minutes, then turn ON the computer..
If that doesn't help, try a new router.
Hope this helps.
My internet connection (DSL 128kbps) stopped working a few days ago. The router(netGear) doesn't detect the internet connection even if the DSL cable is plugged in just right. I already tried replugged the cable, resetting the DSL modem and even trying another router (linksys) but to no avail. I also tried cleaning up the receptors and still it doesn't work. How ever the connection works if you plug the cable in directly to one computer's LAN socket.
We called our ISP provider already and they say that it's not a problem on their side.
