Mark in Seattle –
This cable modem initially appeared to work well with Comcast. It then started to only intermittently forward DNS requests causing loss of Internet. I purchased a different cable modem (Motorola) and all is good again. The issue appears to be the software Comcast downloads into the box, as the rest of my setup (NetGear Wireless Access Point) works fine with both the Comcast rented CM and the Motorola.
