I'm trying to help a friend with his Linksys WRT4GL router. He got it working himself, but then the power was turned off in our neighborhood for a couple of hours and it won't work now. It's on, it says the internet is working, and I can connect to it wirelessly or wired, but it neither sends or receives any packets and I can't access the internet or the browser-based configuration utility.
I'd appreciate it if someone might be able to point me in the right direction.
Thank you, Trevor
