This is a new router, and I had it set up working fine. Connected to a hub that connects two other computers. I had set up port forwarding for one port where I want a program running on remote computers to connect to a program I have (Port Any -> xxxx, directed to one of the computers). Don't think that is relevant, but still.
So problem is, when I now go into the router setup, and click on "port forwarding" tab, it does not open, just waits for 10-20 seconds, then the router restarts. This happens now every time.
What may this indicate..?
