Customer Reviews

5.0 out of 5 stars Great so far. Faster speeds than I am used to.

Set-up new modem went well with Xfinity app. Set-up was easy with Arris App. Got computers going quickly. Usual attaching all other online accessories went well. Just remembering all of the different set-up instructions for all of my cameras, Ring doorbells etc. It is just the normal things you go through with changing out a modem / router. Everything seems to be running well. Much faster than my old modem / router. Very satisfied so far.

5.0 out of 5 stars Worked great for 58 days - then it didn't - Thanks Comcast

You can read my sad tale below if you choose. But a quick summary may suffice. I got the SB8200 and it worked for 58 days. It then stopped working. It was replaced by Arris but the second modem did not work, either. That modem was replaced by Arris and the third modem did not work. The odds of getting three bad modems were pretty near zero so attention turned to Comcast. A tech came out and confirmed that the SNR was way low and the signal levels were out of bounds. He ran a new cable to the Comcast distribution box and installed a new splitter. The third modem connected immediately and worked perfectly. The fact that my old modem (not a docsis 3.1) worked had initially suggested that the problem was the new modem instead of the Comcast line.
