immortal3k3,
You may not need to unplug the modem, in that process. Most cable modems drop IP when they lose connection to the router. Change the router MAC, then power off and on the router, not a warm reboot of the router, but a full power off then on. That should do. And only takes 1/2 a minute.
For some of us lucky people, simply change the router MAC, then from the router config - release DHCP then renew DHCP. NEW IP!!! Within a few seconds. Some devices can do this without anything needing a reboot.
My setup uses Linksys WRT54G v4 or earlier for the router. My modems are some flavor of Motorola (and clones) SB5100 or SB5101. That includes Ambit 250 or 255, Scientific Atlanta Webstar 2100 (r1 and r2), Some Terayons (715 and 715x), 3Com Sharkfin, and others I just can't think of right this moment.
Basically, if the main modem chip is a Broadcom 3348 or 3349, you don't reboot anything. Just change router MAC, drop DHCP, raise DHCP, and GO!
Try those and see what you get.
