You get what you pay for but I think with this little bugger I got more. I have Xfinity and this works perfectly for me. I replaced an old model that I had for about 12 years so anything newer was going to be a big upgrade for me but this does the trick for a cheap price.
I did have to contact Xfinity to setup the modem as the self starter wasn't working. However, I think that was due to me being a little impatient as I contacted them right away when it didn't work. When I was on the phone with the Xfinity tech support the self starter popped up on my web browser so I think if I just would have waited 10-15 minutes I could have done it through the self starter.
