Query: No go with Comcast

I tried two of these modems on my Comcast connection. It would loose the connection (you couldn't ping your default gateway on the comcast network) at random times for as long as 30 seconds at random times.It was impossible to use this modem with Vonage or other services that expect a reliable connection to function.I have lot of other D-Link equipment, and typically recommend their hardware, but I would recommend staying away from this modem at least on a Comcast connection.
