Comcast Xfinity Home Security Camera

Awesome modem. Better than the Comcast Xfinity modem router.

This modem works well, and is compatible with Comcast/Xfinity network.

Works good on xfinity and Comcast cable as advertised, no problems so far.

Easy set up with Xfinity/Comcast. Consistent, fast, solid.

My tech from Xfinity at Comcast thought it was great. Also my tech from AT

Affordable, works with Comcast/Xfinity and paired with RS7800 I'm getting 476mps on downloads.

Seems great, loving it so far. Forgot about needing to register it with Xfinity/ Comcast, once figured that out went great.

After reviewing online Modems compatible with Xfinity/Comcast this product was identified as #1. Since install product has been phenomenal. No downtime, lag or loss of internet transit. Recommen to everyone.

.After upgrading to Xfinity (Comcast) 1 Gig speed tier, I needed a new modem to take advantage. I originally purchased a Motorola MB8600. While the Motorola was indeed fast (spoiler alert: faster than the Arris S33), the Motorola was hugely unstable and unreliable on Xfinity/Comcast (Google it - you'll see its a huge problem). The Motorola was either locking up or losing Internet connection about 5-10 minutes every hour or two! Egads! It was horrible. So Motorola was returned. Enter the Arris SURFboard S33. It activated smoothly and has been rock solid for me on Xfinity/Comcast. It is also a very small modem. The box photos make it *look* large - but it is in fact only 6 x 6 x 2 thick. Quite compact and smaller than most DOCSIS 3.1 modems. It is fast...but, if to be honest it is slower than the MB8600 I had right before this one. My plan is rated at 1000 Mbps down and 40 Mbps up. The Motorola topped out at a very impressive 1014 Mbps down and 41.6 Mbps up. The S33 topped out at 933 Mbps down and 41.7 Mbps up. I ran tests on both modems probably 30 times at all different times of days and night. The above are my best scores. The S33 is consistently about 8-9% slower download speeds compared to the MB8600. But...reliability and stability are far more important than a marginal top-end speed difference. The only other (slight) negative is that the S33 runs a bit warmer than both my older SURFboard model and the Motorola MB8600. It's not hot per se, but does run warmer than maybe most modems. Just make sure to give it good ventilation and it should be fine.

I was using Comcast/xfinity cable router w/WiFi modem, was not able reach to few areas of my house but this C7000v2 is simply great with fast reach. Love it… I am glad I made the move to this router!
