Customer Ratings & Reviews

Excellent workhorse modem for up to 1 Gig. Used with both Xfinity and Cox 1G plans. Not sure why, but it never picked up the overprovisioned speeds in excess of the plan (i.e., 1.25G) while others do (Arris S33, NETGEAR CM2000). It’s rated for above 1G so I assume the ISPs throttle it. But excellent otherwise. Years of use with no problems (see, e.g., S33’s overheating).

No problems internet is functioning as needed. We do not game only streaming media and entertainment.

Wanted a DOCSIS 3.1, 32x8, modem. Got it. And, it works great. My Bad! Wanted a dual-band modem and I did not realize this level of modem, DOCIS 3.1 (so I believe) does not do dual-band. Called Cox and setup was easy and fast. It has virtually eliminated the drops and resets in my connections. Rated it 4-Star solely because it does not allow dual-band. IMHO - It is a Very good modem, and replaces a Surfboard that is 7 years old. Easy setup. Dealing with your cable Rep will, probably be your greatest lag time (good luck telling them what you have and need).

I have no issues, i would highly recommend buying this brand product

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!

We have purchased the Surfboard modems three times before this. The last couple times we went with another brand only to have a confused setup experience. This for us was truly plug and play. All the dread we anticipated was for not. I highly recommend this product.

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.

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.

Solid modem. Able to handle gigabyte speeds easily.

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.

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.

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!

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.

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.

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.

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

It was the best exchange I made with other arrius that didn’t have the router. This one have the WiFi and Router portable . It quick, efficient , lightning fast and installment is easy. I love it! Recommend hundred percent to anybody . That want to save money on equipment fee when getting internet service from Comcast or cable services

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

It hooked up really easy and adapted to the service with ease. Been working great!
