Best to wait 24 hours (48 would be even better if you can)
Reboot everything, then get a command prompt up again and type:
ipconfig /renew
If that doesn't get a new IP then it's unlikely that you'll be able to change it.

This will only release and renew the internal IP address (i.e. the IP address behind the router)
Connect your PC using the USB cable to the modem, as this will give you a different IP address. Leave as long as possible (48+ hours) so the old IP address is released and then used by another customer. Then swap back to the ethernet connection via your router.

Please note whilst using the USB cable you wont have the router hardware firewall.
