When I swapped modems, I did this much:
To activate modem:
Start with all gear off.
If you have a router, leave it disconnected for now.
Connect modem to PC.
Power up modem(wait for sync)
Power up PC.
Bring up Internet Explorer. You will be auto directed to Comcast's activation page.
I followed the prompts to download the software (planning to uninstall it after getting connected), but nothing happened.
I had an IP, gateway and DNS servers, but couldn't go any further.
Called Comcast, gave my MAC address, did the requested power cycle and reboot and never needed to install their software.
It's easier for them, I think, if you get to the part where the IP is assigned before calling them.--
