Customer Ratings & Reviews

Love it, got rid of my old crap ,no problems with this one.

This modem is great, set up is relatively easy - I still had to call Comcast for final steps - it is approved for Comcast Business. The only issue I have is that it is not VOIP compatible. I have a VOIP phone system and could not use it. Unfortunately, there isn't a single modem I could find out there that is both approved for Comcast Business and VOIP, so I had to make a decision and the faster service provided by the modem wins, and I no longer have a separate phone at my desk.

Great speed, easy to set up! Has 2 LAN ports which allows me to connect 2 routers.

Easy to install. Fixed my problem. Internet works and is fast.

I had to replace my old and outdated all-in-one wifi modem router. This new modem has greatly enhanced my speed and connectivity with less dropped connections.

Let's face it: Best Buy is the best place to buy cable modems so that you might save a ton of money over getting them anywhere else. This ARRIS cable modem performs better than any than I've ever used, taking full advantage of the highest speeds available through my carrier. It's easy to set up and its numbers and codes are easy to read and report to your carrier when connecting.

Great modem! I never have to power cycle it and I get the speeds I pay for. Latest specs so wont have to upgrade for a long time. Its DOCSIS 3.1 with 32 download channels with 8 upload. Even has a download and upload light to show if you are getting DOCSIS 3.1 from your ISP.

I returned the ARRIS Surfboard SB8200 because it was more advanced than what I needed for the internet speed I currently have with my cable provider. The modem itself is high quality and clearly built for much faster plans, but I couldn’t fully take advantage of its capabilities, so I chose a model.

I purchased this modem as I had received 10 years out of my old modem and thought that having updated equipment with the latest docsis 3.1 support would be able to get me another 10 years before having to buy another modem. All I had to do was contact my cable company and give them the new MAC address of the modem and I was up and running in about 10 minutes.

I went into Best Buy and told them my provider, and this modem was one of the few that was listed as compatible. It wasn't what I had intended to get going in and took a minute to set up. Overall I'm very satisfied. I've been using this for over a year and it's been pretty solid. I have basic cable internet used mostly for streaming video and some gaming and this has done the job just great.

Awesome 3.1 router.Wentahead and future proofed myself and got the 3.1 even though 3.0 is all that is needed for this area.But eventually you will need 3.1 so go ahead and get this one.Great modem and real easy to connect.I can tell you it works worth Comcast and WOW.Might want to catch it on sell as it wasn't when I purchased and had to grab my ankles.

Bought this 3.1 cable modem so that I could utilize the increased speeds provided by my Comcast/Xfinity service. It has worked perfectly. I subsequently had to also replace my router as it was not capable of throughputting the increased speed, but now I am getting almost 900Mbps on both wired and wireless connections. Not paying a monthly fee to my internet service provider (ISP) for a modem is a plus. I have always purchased and not rented my modems. Note that modem does not provide any wireless signal, so you'll need a separate router for that. You should also know that this modem does not handle phone service, so if you are getting your phone service through your ISP, this is not the type for you. For the typical modem/router setup, this is a good and fast modem.

This modem is easy to setup, and provided me with my plans best speeds. Would definitely recommend for anyone in the market for a quality modem that won't give you issues now or in the future.

Great modem, works flawlessly. I would give it 5 stars but only 1 of the 2 ethernet ports is usesble as a network port....read the fine print.

I am moving from an all in one modem that would cut out all the time, to this beast! To be fair my network setup is about 3x as expensive now, but it was completely worth it. Using this modem, a pfsense router and intrusion detection system, and a unifi AP wifi unit, my network is more secure, more reliable, and actually much faster!

Easy to hook up and get running .No problems as of yet.

very good speeds and good quality. easy to set up and use.

I was using an old 4x4 SB6121 for the last 6+ years. Chose it because of the price. Didn’t know what I was missing. This one is so worth the upgrade. Two kids streaming vids and both the wife and I working from home, we no long have lag issues. Yes, it is on the more expensive side, but with DOCSIS 3.1 you are good for years to come.

Easy to install, great speed, no reboots so far, would recommend to a friend

Great product works great easy to set up fast internet
