Can Comodo Firewall Affect Modem Acquiring IP?

Hey folks, I’ve gone from having wireless setup to wired into Shaw. There seems to be some issue with my modem autoinitializing and obtaining an IP address upon boot. When I unplug the power cord to the modem and replug it, I can access the internet. Is it possible that overzealous settings on Comodo could restrict the modem getting an IP address when I boot?

I know I"m reaching a bit, but tried almost everything else, swapping modems, going through all the dialog boxes in the networks dialog boxes under XP.

Maybe its time I switched to Mac!

Welcome.

Just to clarify. It’s your modem failing to obtain an IP address or your PC, via your modem, failing to obtain an IP address?
