Unsure what happened, but router just stopped working. Tried to login - unsuccessful. Tried to reset router, then login - unsuccessful. Now I'm getting a white screen stating that firmware is required and to Upgrade Right Now. I downloaded the latest upgrade, and attempted to upload. Router goes through the process then reboots. Reconnecting to the default 192.168.1.1 - the same Upgrade Right Now screen appears. Any thoughts how to resolve this?
