Customer Ratings & Reviews

I've had this Cable Modem for several months now and have had no problems whatsoever with it. Installation was easy and only required a phone call to my cable company to activate its use (as well as returning my old Mediacom Modem). Now I no longer pay a $5 rental fee to my cable company, which over time will pay for the Modem. My only gripe is not with the Modem, but with my cable monopoly that I'm stuck with if I want fast internet speeds!

Unit is solid and does its job well, three weeks as of this writing. It is not complicated to operate out of the box, and does not need any attention after connection has been established. The unit gets quite warm. Here are two important "lessons learned" connecting this unit to Comcast Xfinity: (1) You have to call Comcast to authorize the device; it is not automatic upon plug in only. (2) If you run into a problem that wired internet works, but wifi internet does not seem to work but rather, shunts you to a Xfinity login page: You have to change the DNS server address on your wifi router (downstream of your SURFboard). Change it away from the default to a non-Xfinity, non-Comcast server. My successful choice was Google, 8.8.8.8 is that IP address. To find this out took my untold hours; not Arris' fault, but I am aghast how not available this info was on the wider internet.

We had been having issues with our internet so one of phone no-support techs said the problem was our modem. So I go bought this modem as a replacement - it had twice as many download channels as the one that I had and I think that i can notice a difference. Setup was easy - plug and play right out of th box. The internet issues were no due to the previous modem as we are still working through them with the provider.

When my last SURFboard modem finally gave up the ghost after 10 faithful years, there was no question on its replacement. The setup required assistance from Comcast to get it up and running despite the easy instructions outlined in the manufacture's instructions. However, you can't beat the performance and reliability compared to other modems in this price range.

I purchased and installed two of these units, one in a rental house we own and the other in my own house. It installed perfectly with Comcast without having to contact customer service. Just make sure you know your account number and phone number associated with your account. We have had no performance issues. The lights are bright, however. It is not a problem in the office but could be annoying if installed in a different room.

We desperately needed to replace our old modem and didn't even realize how badly it needed replacing until I bought this one. Have had it since August, 2021 and it does a fabulous job with connectivity. I've never had to reset it even once after connecting it to our coaxial cable. Speeds are phenomenal too! Love it!

Easy installation. Worked as described. Brought me into this century. Fast.

Easy to install and works great. Very affordable. Save me money by not renting from cable provider.

I purchased this to replace a two year old Arris 6121 that worked flawlessly for two years. But when my ISP, Comcast, pushed up my speed to 200mB, the old modem couldn't keep up. Just like the old one, the new one was super easy to install and worked perfectly right out of the box. Although I am only paying for 200mB, I consistently get about 240mB and have gotten speeds as high as 260mB. Until proven wrong, I will only buy Arris modems.

This modem hasn’t disappointed me yet. I have no problems downloading or streaming any movies. I have my home alarm system, tv, cameras, personal devices, etc. connected to the internet and I have no disruption in my connection. This modem is able to handle the internet speeds my plan gives me which is up to 60 mbps and I know it can handle more if I needed more which I don’t. I just need to update my router now.

I decided to unbundle and I wanted to purchase my modem rather than rent one from the cable company. I am somewhat computer challenged when things get too technical. The salesman explained the different modems and made a recommendation as to what he thought I would need. His recommendation was a good one. It was easy to set up. Once I got the cable company straightened out, all worked smoothly. And it does everything I need it to.

Easy install, great product and compatible with Xfinity.

This is a really fast modem but I was maxed out at around 150-170 Mbps with Comcast Blast speed. It didn't give any extra speed compared to the SB6183 (I was only provisioned with 8 downstream channels with both modems) so if you already have the SB6183 with Comcast Blast, don't bother getting the SB6190! Just wait for the next wave of DOCSIS 3.1 modems.

Fast reliable modem. Notice a marked improvement in my download speeds. Easy set up

Dependable modem - last one worked for more then 5 years. This exact same product has been on the market since October 2015 and is still for sale! Tried and true. As with anything connected to a cable that runs from outside your home, any electrical surge can take this out. That's what happened to mine, here in Florida, the lightning capitol of the US. Bought the exact same model, called my Internet provided and was back in business in about 15 minutes...speedy and maintenance free. (Your ISP provides the firmware updates directly.) 1Gbps internal LAN to your home router, and on my Xfinity, it is capable of up to 800 Mbps (depending on your plan, and the ISP speed "tier" options). No need to buy the "latest and greatest, more expensive" when the Wi-Fi maximum speed is 9.6 Gbps maximum throughput across multiple channels, and Wi-Fi 5 offers a maximum of 3.5 Gbps. Your home network is only as fast as the slowest common denominator.

Very easy to set up, Speed is great! COX compatible. Very easy to view light indicators

Great modem for the price. Always go to Best Buy! Easy to use and to set up. Would recommend to everyone. Small and compact as well. Buy one now for 1 GIG speed.

Easy set up, alot smaller than my last, and more reliable.

Works Great. Simple setup and connection. Super fast!

Very good price to buy instead of renting for $6 a month permanantly from comcast. It is a replacemnet for my old moterolla surfboard that couldn't keep up with the new higher speed internet which was sad beacuse it still worked just not fast enough. this is a docsis 3.0 which can do most all speeds out there from any internet provider . easy set up and not a problem yet with it.
