Re: Forcing a Cable Modem to get a new IP
When you plugged it directly into your laptop, did you get the same IP as your router did?

If you got a different IP on the laptop, but the same one back on the router, spoof the router to a MAC address of a network card you own. (As this is more legit than making one up that is assigned to someone else, and as long as that network card is always on the LAN side of your router, it shouldn't cause any issues).

Usually the modem's MAC address is used to assign it a non-internet (private) IP in the 10.x range, and the MAC address of the client PC is used to assign the internet IP. I'm not familiar with the CMTS system that Charter uses, however, so it may be different.
