How to Reset an IP Address for Time Warner Internet

When a computer or router connects directly to a Time Warner cable modem, the hardware Media Access Control (MAC) address of the device connecting to the modem is remembered by Time Warner's DHCP database, which is responsible for assigning an IP address to the cable modem. This means that each time that device connects to the cable modem, it receives the same IP address. To reset the IP address for Time Warner Internet, the device connected to the modem must be changed temporarily.

Step

Disconnect the power from the Time Warner Internet connection.

Step

Connect a different Ethernet device to the Time Warner Internet connection.

Step

Power on the Time Warner Internet connection and wait approximately 90 seconds for the device to synchronize. At this point, the cable modem is using a different IP address.

Step

Repeat the previous steps with the exception of connecting the original device, such as a computer or router, back into the Time Warner Internet connection. Because the IP address was reset when the previous steps were performed, it is is reset again to a completely new IP address when the original device is reconnected.
