One of the 2600 routers we are working with will randomly reset itself. When it does this it will also lose its configuration. The running config has been copied to the startup config and the problem still occurs. I have also tested this by setting IPs for the interfaces, saving the config and then turing it off. When the 2600 restarts it comes back up with a clean config. Is this a hardware problem with the rotuer or is it something in the software that could be causing the problem?
