Product Summary
For those of you who have a gigabit plan (2000 Mbps or less) and wish to future-proof your modem, the Motorola MB8611 is the optimal option.
Due to the fact that it supports DOCSIS 3.1 and includes a 2.5G ethernet connector, the MB8611 is an excellent cable modem. This makes it future-proof since you won't need to buy a new modem when Xfinity improves its internet to DOCSIS 3.1. Additionally, DOCSIS 3.1 supports DOCSIS 3.0 and is backwards compatible with it.
Another excellent feature is the 2.5GB Ethernet port. Because the modem is now compatible with 2500 Mbps internet plans.
And even though it seems extravagant right now, it won't in a few years.
I thought I couldn't choose any other modem as the top choice because it comes with a two-year guarantee and (in my experience) outstanding assistance.
Overall, the Motorola MB8611 is a modem that you can purchase now and leave behind for the foreseeable future. Considering that it will last a very long time.

A cable modem designed specifically for Xfinity Voice is the Netgear Nighthawk CM2050V. This is so that it can support VoIP and since it includes a phone jack and offers internet.
You may add a third participant to your two-party chat since it features two integrated phone lines that facilitate a 3-way conference call.
Furthermore, call forwarding is supported. You may then divert incoming calls to different phone numbers thanks to this.
The DOCSIS 3.1 standard is also supported by the modem. This, along with its 2.5G ethernet connector, gives it an astounding 2500 Mbps of bandwidth.
One that Comcast doesn't even now provide, enough to rapidly download almost everything.

Product Summary
If you're on a tight budget and subscribe to the Performance internet plan, the Motorola MB7420 is your best bet (200 Mbps).
The modem is "just enough modem," which means it will work for you right now but won't in the future.
This is due to the fact that DOCSIS 3.0 only has 164 channels. Which is the Xfinity modem minimum requirement (just modified from 84).
Therefore, if you want to increase your internet package soon, do not purchase it.

If you need a gateway and are using the Blast! Pro internet package or below, the Netgear C7800 is a suitable choice (800 Mbps).
During testing, the Wi-5GHz Fi's band averaged 513.64 Mbps at a distance of 5 feet.
enough for a family of 5 to comfortably enjoy 4K movies at the same time. But only if your internet package is sufficiently fast.
The modem has 328 channels and is a DOCSIS 3.0 modem. Unfortunately, since DOCSIS 3.0 is all that is available, this does not make it future-proof. It still performs superbly, though, thanks to all the channels.
In addition, it's a reliable gateway that offers great value for the money.

(Best Performance)
Product’s Specifications
-
Type: Modem/Router Combo
-

Max Wi-Fi speed: 800+ Mbps
-
Channel: 32×8
-
DOCSIS: 3.1
-
Warranty: 1 year
Today’ Best Deal
Reasons to buy
-
Future-proof.
-
Class-leading performance.
-
Excellent range.
Reasons to avoid
-
Pricey.
Product Summary
One of the best gateways I've tested is the Netgear Nighthawk, which is compatible with all Xfinity internet plans.
Since the internet package we had access to only offered 800 Mpbs, we weren't even able to test it at its maximum speed.
800+ Mbps, 583.15 Mbps, and 298.47 Mbps, respectively, were measured at 5 feet, 25 feet, and 50 feet. Use of the 5GHz channel was universal.
These outcomes are astounding for a modem/router combination and would be sufficient for more than a dozen simultaneous 4K movie streaming.
In all honesty, the CAX80 is a bit extravagant if your internet plan is less than 400 Mbps.
However, the CAX80 is a wonderful alternative if you don't think you need the extra capabilities and are wanting to achieve the speeds you are paying for.
