One little but very important detail for Cox & cable modems - they hold
out for a single MAC address, I presume as a security caution to keep
them from being hijacked.

If you pull the power plug on the cable modem for 5 minutes and then
plug it back in, it will reset the modem, reload its configuration from
Cox's TFTP server and allow you to switch MAC addresses
(computers/network cards)

Try it
