New Business Gateway CGA4332COM hangs during initial config; replacement does too
Ordered new Comcast Internet service with 5 static IP's. The gateway hung during initial configuration. Support replaced the unit, the new one hung too! This seems like a firmware bug, how do I get competent support?
By "hung" I mean the gateway suddenly went to a login prompt, and when I entered the login credentials it just looped back to a login prompt. Support was able to see the modem enough to reboot it, but they couldn't make it work either.
For initial configuration (using http://10.1.10.1), I changed the default password, changed the DHCP/LAN address to my existing LAN subnet, changed the name and password of the Wifi network, and used the "Port Management" feature to allow specific ports through to certain static IP's. I don't think it died at the exact same spot both times, but I was about this far along each time.
Support doesn't seem to have any idea what to do other than replace the gateway, and that doesn't help. Is there level 2 support available to small business clients? Has anybody seen a problem like this? What can I do other than give up on Comcast Internet service?
