Notes and Useful Information:

Thomson, the manufacturer of the RCA DCM245 cable modem, has recalled the Power Supply on this model. A limited number of the Power Supplies distributed have a bad circuit.

When this modem is in stand-by mode, the Internet/Power light will be off. All other lights will operate normally. While in stand-by mode, the customer may still be able to release/renew an IP address without any problems. Please keep this in mind when troubleshooting PC connectivity issues.
