I recently installed this firmware and things were going quite well. My speed has increased but on the negative side, I can't use my wireless file sharing. I can see the workgroup computers, but I can't access them. I tried using a cat5 from the router, and it sees everything fine. It might be a setting that I am not seeing correctly on the router page? I have a WRT54G v2. Thanks for your help EDIT - Nevermind, Loopback was enabled.
