Customer Ratings & Reviews

Great product my Internet is no longer lagging. Everything is running smoothly within the household.

Easy to hookup and going in no time. Great Speed! From box to surfing in no time. Works great.

We needed a new modem due to upgrading our internet speed. The investment in this cable modem is a good alternative to an internet provider's monthly rental fee for a potentially inferior product that we would not own. The up-front cost should be fully recovered in about a year and a half. There were no problems with setup or ISP provisioning. Speed is good, works as expected so far!

I had the Arris SB6183 for years, never had any issues. I decided to increase my internet speed with my ISP. Bought the SB8200 to accommodate the increased speed from DOCSIS 3.0 to DOCSIS 3.1. The SB 8200 was extremely easy to set up, just called COX and in 10 minutes everything was up and running. It has been working falsely as did the SB6183. Ordering online from Best Buy was fast and easy.

Superior Brand. Superior value. Easy to operate excellent price. Trusted&Quality brand

This modem replaced an Arris 6183 that died when our building was hit by lightning. Set up with Xfinity in Houston was a snap. Went through a couple of firmware updates and we were up and running in less than ten minutes. This unit is much more reliable then my previous 6183. We pay for 150mbps with Xfinity. We consistently show 175-185 mbps down with 12-23 upload. A bit on the expensive side but still highly recommended.

Not bad for the price if you have fast internet it has a second Ethernet for 2T very easy to hook up and some time you might have to call your internet provider

Great product easy to install. Internet is fast and not spotty now. Works very well.

Easy to install. Works well. Much faster internet. Well worth price.

I've been using Surfboards since they were originally manufactured by Motorola. I've found them reliable and solid performers. I've only upgraded to a new one b/c I needed DOCSIS 3.1 to make use of higher tier Cox speeds. New cables, new modem? Now my connection rocks and doesn't slow down when I'm working-from-home and the S.O. is streaming and playing MMORPGs!

This is my fifth Surfboard modem in two decades, and all have served me without fail (unlike the RCA, US Robotics, and Scientific Atlanta models I also had during that time). I had a protracted move this year, and needed to keep my subscription with the MSO at my old house for my wife to work from home. While there was nothing wrong with the SB6180 I had been using, I could not take it with me to the new house, so needed something at the new place-that would also give me room to grow. I only have a 150/5 plan from COX right now, but this modem will allow me to switch plans all the way up to their "Gigablast" service if necessary. It takes a little longer to boot and sync than previous models I've had (2-3 minutes vs the 40-60 seconds of the SB6180), but that's hardly a major issue. I have the modem and router on a UPS, so the occasional power blip doesn't cause any downtime issues. This thing will run a very long time on a 500VA UPS. These modems aren't cheap at around $170-180, but it's also the first one I've bought new (the SB6180 was only $36, but this was due to being pre-owned and on the market for quite a while). Since I expect to get 5+ years of service out of it, it will pay for itself in about 16 months when considering the monthly fee to lease one from my ISP-leaving me with 3.5 or more "free" years. Buy one of these with confidence.

Fast shipping! Easy to hook up! Work perfect! I love the brand new one!

The modem was fairly priced and easy to install. I should have done it years ago. I chose Best Buy because they were able to recommend the right modem to purchase and hook up to my Internet service provider.

Bought this about two weeks ago. Easy Setup with my new router and upgraded service to gigabit. I have been monitoring traffic and do get the desired download speeds with Xfinity which supports this modem. Overall worth the upgrade my only gripe is that Best buy states it comes with an ethernet cable in their product description but the box contents as well as the details on the product box itself do not mention any includes. Removing a star in hopes Best Buy fixes this product advertisement issue.

Good product. Setup was easy, but I had to let everything sit for about 90 minutes before the modem started working with my WiFi Router device. Note to self: Just wait 90 minutes and be patient. It seems to run updates or something that didn't allow me to connect to the internet for about that timeframe. Works great since then, I work from home.

Upgraded to this Modem and its pretty fast, reliable, and easy install!

I was looking for something to replace the SB 6121 because it was already 5 years old and started losing connections. When I got this one, I could notice a difference in how quickly my web pages loaded in even without changing the speed of my Interent. I already had success with the Arris line, so I decided to upgrade to this model. So far super fast and reliable.

It was the highest rated modem that runs docsis 3.1 which is required for gigabit internet and fairly rare. Also priced accordingly. No frills but good modem.

It is a fantastic modem. If your ISP support DOCSIS 3.1, you can't go wrong with this item. My Internet plan is 900 Mbps download, 20 Mbps download. Almost every day, doesn't matter what time it is, I was able to get up to 700 Mbps constantly. Please ensure to pair it with a decent latest and greatest Wi-Fi router.

Finally stopped renting from the cable company and bought my own. Not only was it super easy to set up but, my internet speeds increase and we’ll as allowing me to customize my Modem Settings. Once providers start allowing higher speeds, this device will be ready to handle the higher download/upload speeds. Highly recommend this product!!
