If you change the device that is plugged into the NTL modem, you need  
to kill the power to the modem for a while.
The modem stores the MAC of the device that connects to it, if you  
don't power it down your new router won't receive an IP from NTL.

Eh? Sorry I don't follow this. I assume the perfect solution would to  
replace the big old PC based firewall with your new little low-power  
wifi router/firewall.

Is there a reason you need to keep the CC Firewall?

NTL -> Firewall/Router/WIFI AP/Switch -> Machines : Sounds a better  
more clean solution for home use.
