If his cable modem is similar to mine, it recognizes only one NIC and must be power cycled in order to attach a different NIC. After killing dhclient and restarting it, he will also receive a different IP address from his ISP. The important thing is to kill the power to the cable modem for at least 1 minute then power it back up again.
