FYI Comcast is phasing out support of the SB6141 and recommending people go to the 6183 … I had the 6141 and it worked great … I recently upgraded to the 6183 when I got a notice email from Comcast ending support (eol) for the 6141 , While I am sure they will support it for the time being I am not sure how long that will be and/or if they will be allowing new activations of SB6141 modems… just an FYI for people who use Comcast (best to call their support and ask if its still OK for this model)
you can see this thread where I posted a copy of the notice I got (and I personally owned my 6141)
