I have a Linksys WRT300N router and it's work perfectly ever since I got it, but I just moved into a new house and it wont work anymore. If I connect my pc directly to the internet it works fine, but when I plug it in through the router it's dead. The router display says everything is fine and connected. I tried resetting it and reinstalling the firmware but nothing. It can't be my computer because I tried connecting other devices to the router and they don't work either. Does anyone have any idea on how to fix it before I go out and buy a new router?
I just though of re-entering my internet connection's MAC into my router and that seemed to fix it. Sorry for wasting your time.
