Do Not Buy Modems List

These are cable modems listed with a bad Puma 6 chipset. You may see other sites with many more faulty modems listed. They have completely overdone it and went over the top listing modems with all Intel Chipsets as bad. However, this not the case. Only those with the Intel Puma 6 are faulty. Just another reason XFINITY Modem Reviews is around, that is, to help the consumer make an informed and accurate decision.

Well Worth It

Well worth it - Very impressed with the quality. It looks and even smells like a new unit, and I am 100% happy with my choice to buy refurbished. I switched from an Xfinity Gateway unit, and pay for speeds up to 100mbps down.

Best Stand-Alone DOCSIS 3.1 Cable Modem

The ARRIS SB8200 is compatible with more cable providers as opposed to its Netgear Counterpart CM1100. This is truly a future-proof cable modem that will handle speeds up to 2 Gbps. However, the SB8200 is not just for Gig-speed tiers but lower speeds as well.

Incredible Upgrade

Finally decided to upgrade my Xfinity-provided and woefully unreliable Modem/Router combo to this Modem and Netgear R7000 Router (which I also highly recommend) and the difference is incredible! Before I was only getting 90 Mbps and frequent dropouts and now I've been getting a consistent 200 Mbps (keep in mind I'm only on a 175 Mbps plan) and so far absolutely no dropouts or slowdowns! I was expecting a minor improvement but I was not expecting this much of an improvement! The set-up was straightforward and easy as well! I would totally recommend this Modem for anyone looking for an upgrade with Voice capability and is definitely worth the price (now saving $14 a month in rental fees) All in all I am very happy with this purchase and will be buying Netgear products for years to come.

Thanks for the review

A++ WiFi 6 / DOCSIS 3.1 Modem

The CMAX6000 is a perfect combination of a DOCSIS 3.1 and WiFI-6 cable modem. It is approved by Comcast XFINITY for tiers up to 2 GBPS. With its passive cooling technology, overheating and noisy fans are a thing of the past. This is surely the last cable modem you will need for years, or maybe decades to come.

Great Modem For Speeds Up To 200

This is a good modem for Comcast if you subscribe to speeds up to 300 Mbps. If you intend on boosting your speed with XFINITY in the near future, consider a DOCSIS 3.1 modem. Although more expensive, a 3.1 modem is backward compatible with 3.0. A 3.1 modem would be the last you would need for at least 10 years, provided it lasts that long.
