Mot SB6121 and is V3 according to the specs online.  I have a modem and 
a separate router, ASUS RT-N53.  Newegg was selling them as a pair so I 
assumed (possibly bad) that the worked OK together.  I know the SB6121 
is on the Comcast approved list and has three stars.

Currently there is a Comcast supplied combo modem/router which I am 
replacing.

Thanks for the info, that's what I needed to know.

Jim.
