Change MAC address

DCM476 - DOCSIS 3.0 cable modem mac address

The cable providers allocate IP address using DHCP. It looks at the MAC address of the computer (or router) it is communicating with and goes from there.


Change MAC address::
I needed to get my IP changed so I called up my ISP and told them. It took them 10 minutes to reset it.



So,
1) Unplug your cable modem for about a minute
2) Direct connect your PC or laptop to the modem
3) Power On Cable Modem (on surfboard, wait for the "Online" light to come on constantly)
4) Wait another minute.
5) Repeat steps 1-3 for Router.

It might not be possible. It's assigned on your ISP's end. I've noticed the same thing with my SBC DSL modem though. I only get a new IP every month or so. My guess is that the IPs are assigned to the modem for long periods.

RCA / Thomson Modem Hack Discovered

An anonymous reader writes "Those un-employed modem hackers are at it again. The group known as TCNiSO has released a very interesting hardware modification for RCA / Thomson cable modems. The modification is done by grounding the bus clock on the serial EEPROM which throws the device into a diagnostic panic mode. Then by using the debug tools from the embedded console to reprogram the EEPROM, a user can permanently enable a developers menu which gives complete control of the modem, such as modifying the hardware addresses or flashing new firmware. Now if only these guys can figure out how to enable the Bluetooth features on my v710 phone..."
