After inserting 2nd NIC my cable modem stops working

[Chris Dickens]

Actually, what I did was I did "config t" -> "interface cable 0" and
edited the interface's "mac address" to the dotted triple from my older
RCA CM thinking that that would be sufficient (and I wouldn't have to
bother @Home) But it appears to be more than just the MAC address, OR
changing this mac address via the terminal still doesn't change the
address that's sent out on a DHCP request. (What could it be useful
for?) 8-)

Any ideas?

Thanks,
--Chris
