From tech support via e-mail:
Set your computer up with a static IP address in the same range as the
router. You would set the ip address subnet mask and gateway. the ip
address would be something like 192.168.2.5 and the subnet mask would be
255.255.255.0 and the gateway would be 192.168.2.1 and then once this is
done then you will have to reboot your computer. once you have done that
log in to the barricade and it will entter a recovery mode. Once it enters
that mode use the same firmware that you used when the unit crashed. once
this is done you can set your computer back to the origonal settings and
you should be all set.
Update: Doing what "I think" they're saying (?), I go into TCP/IP properties where I can manually set those lines but it still go online that way so I'm now back on hold (I'd say POOR technical support, not impressed)
The problem here wasn't the router either as I had to once again reboot the cable modem (no router, one PC) so it's something with the cable modem or RR. So.....once I get the router working maybe RR can tell me what's REALLY wrong here
Update: Called RR,
RR says everything's looking OK from their end so they're sending a tech over on 1/5.
