Customer Ratings & Reviews

Very much plug-n-play. Did online chat with cable vendor to add the MAC address and it was up and running. Internet access speed is more than double the speed I have at my company. Love the fact this is forward looking for Gigabit speeds with DOCSIS 3.1 should be good for several years of operation. Also love not paying the cable provider monthly rent for a much slower product and will recoupe cost within one year.

Outstanding compared to my last modem, I would recommend this product to anyone.

Huge upgrade to my old modem. Great speeds and ridiculously easy to set up

Outstanding modem for the price. Synced up quickly when provisioned. Second one I've owned because someone dropped liquid on the first one.

Small and compact able Easy to install Great to explore fast internet

After decades of being a captive of the large cable companies, I finally decided to leave that nest and live in the new universe of live streaming! Had to keep my internet from the big provider BUT I didn't have to keep renting their modem. This unit was recommended by the company as being compatible and it is. Not only that, it's much better than the one I was renting!

good speed....good performance....would recommend.

My old one died after a couple years and had the protection plan walked in and walked out easy peasy with a new model. Works great.

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

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.

Installation was easy and a brief session with the Xfinity app allowed it to connect and be immediately useful. Purchased the modem to provide increased speed/reliability vs the Comcast-supplied equipment. Noticed no difference. This unit also does not support a phone, so it was exchanged.

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.

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

I had Xfinitys 300 MEG plan before and this Modem killed it. Always got 300-350 Meg. Never a drop out. Worked like a charm. NOW.... I updated to Xfinity GiG Plan 1.2Gbps (1200Meg). I was told by some the SB6190 would work, others said no. The specs on the 6190 lead you to believe it will work. Well.... it will work BUT you will NOT get all the speed you are paying for. I got 350 to 750 Meg. The 750 was only early in the morning. Daytime was 350-650Meg. An Xfinity rep ( a smart one) said "you MUST upgrade and the SB8200 is acceptable and approved for your Xfinity Gig plan" The results>>>>> I got the SB8200 and speeds are now 850-1050 Meg... day and night. I am too far from an pole amplifier to get the 1200 but thats OK. If you have Xfiniity Gig , to hell with the specs on the SB6190 box. Get this SB8200... it works! Do we have a Gig? Yes we have a Gig!

It works just fine. The set up was easy enough. It's fine.

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.

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.

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.

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.

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.
