I'm experiencing a bizarre problem with my new Comcast Business Gateway (Netgear model). Initially, when I power it on, everything works. Within about 5-10 minutes, it stops responding to HTTP traffic. The routing functionality continues to work normally, but it becomes impossible to examine or change the configuration. I'm trying to get IPv6 working, and having to unplug the gateway over and over again is starting to get old.
Is this bizarre behavior typical for these Netgear routers or did I get a dud?
