I have xfinity performance pro which is rated for 150 mb/s down and 5 mb/s up. I've been using the Arris SB6141 modem which is 8 channel down x 4 channel up, great modem, no issues but it's speed maxed out at 120 mb/s down and 5 mb/s up. I figured what the heck might as well get the speed i'm paying for, so I purchased the Motorola SB7621 which is 24 channel down x 8 channel up. Internet speed is now 180mb/s down and 6mb/s up with a ping of 19ms. I am happy that I am now getting the speed I am paying for. Yes the upload speed didn't change much but that is because xfinity does not support 8 channel up in my area. This means even though this modem supports 8 channel up it only shows 4 active up channels when you log into it, this is not the modems fault, this is xfinity's doing. The download channels are fine, all 24 channels show up and are active. Yes, I could have purchased a 16 channel down and 4 channel up modem and received the same current speeds but at the time of purchase this modem was less than or the same amount as all the 16 x 4 modems. By buying this Motorola I can upgrade my internet speed down the road and still be covered. Another good thing is that this modem has the Broadcom chipset not the Intel puma.
The modem comes with good instructions and is well packaged. Setup was a breeze. I didn't have to call xfinity. All I did after I hooked up just the modem to my PC was navigate to motorola.com which brought up the xfinity activation page. Then just log in with your xfinity credentials and follow the prompts. Very easy and welcomed as I didn't want to sit on the phone talking to xfinity support.
I never do reviews but I figured this little box deserved one and hopefully this helps someone.
