Customer Ratings & Reviews

Strong and true. Relatively easy to get going (ISP had to provision of course...). When a reboot is required, it comes right back up and keeps humming along. Speed is way more than I need. Very pleasantly impressed with Arris.

I had one i ordered. I am sure it was a returned one cause it acted like it was activated before and didn't work well. Returned it for another and works perfectly. I run this on my new night hawk x12 wifi 6 router and on my cell over wifi speed are almost 900 mbps. No dropped signal or anything works great. Always have good experience with surfboard models

Well, *that* was simple. I purchased this for an upgrade to my older Surfboard (a SB6183) to get the DOCSIS 3.1 speeds, and verified its support on Comcast/Xfinity. I plugged everything in, downloaded the Xfinity app on my iPhone, entered the MAC address, and in about five whole minutes was back online. Easy peasy!

I've always enjoyed this modem. Never gave me any issues. This is the 2nd one I've purchased in about 10 yrs.

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

Normally get 10% more speed than I’m paying for, ow I’m getting 17-20%. My old modem just decided to die.. Was also the Arris brand, one down from this model. (SB6190). Paying for 800 was getting 860-880 wired direct, now I’m getting 925 on the low end and have occasionally seen as high as 986. Old modem was not know to have bad latency for gaming as I was based on an intel Puma chipset. This one uses Qualcomm chips and does seem to do better when gaming on my Xbox. The LED’s while similar in arrangement to my old modem the colors once fully connected to my ISP (Comcast) are now different as the download still glows Blue once channels are bonded, but the upload only goes blue when bonded on IPV6. Even set to IPV6 I’m not showing upload bonded, however like with he download, I’m getting 20% better speed than I’m paying for. So overall no complaints at all. Although it does have to Ethernet connections on the back, you can ONLY use both if you ISP has the ability to give you two IP addresses AND of course you have fo pay extra for that.

I want to start by saying that WOW cable's website did NOT say it was compatible. But for everything I could find it was the same as the model CM8200 on their list just white instead of black. So I called and after about 10 minutes on the phone with the guy he was able to confirm that it was indeed compatible. Now my old modem, the SB 6141 was having a lot of issues with packet loss and slow speeds. The guy who came to trouble shoot claimed with gigabit internet I would not see over 700mbps due to hardware limitations no matter what I bought. I couldnt believe it. So I started looking and found this one. Easy to set up, activated over the phone and instantly started getting speeds over 850mbps OVER WIFI! Yea so it solved my problem and doesnt have that pesky issue with packet loss. Been dependable so far too, havent had to restart it. No latency problems. No real complaints.

I have gigabit speed connection but was getting only 100mbps speed max. After trying multiple modem models (and routers thinking router issue), bought Arris Surfboard modem. Very easy setup and straight away I'm getting 700+mbps speed peak. Glad finally was able to get benefit from what I pay for!

Excellent cable modem. Easy to set-up, but you MAY have to call your ISP to add this to your account before you can surf the web. We have Spectrum and they require you to call them to activate the modem. Still, a hassle-free set-up!

Was skeptical of mesh system but bought this router/modem and instantly increased speed almost 5x! Thus far haven’t had to touch since install which took maybe 10 minutes through my internet provider. Sorry I didn’t purchase years ago.

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).

What can I say? Installation was fast & easy and it's performed flawlessly to date. Highly recommended!

Its a modem and it works. Best Buy keeps asking for a review on this modem and I kept thinking theres nothing to review. Theres nothing to comment because it just works. No issues, no problems, no downtime. Plug and play working.

Quick install to replace an old Motorola modem and incredible increase in performance. Purchase was seamless, courteous, professional and fast. Most productive modem we have had in many years of internet work and immense reliability for working from home in the midst of the CoVid-19 pandemic.

I love this modem. Very easy to set up and provides blazing speed to my mesh network.

Owned for over a month and has worked fine at the expected speeds for my internet plan through RCN Astound (200/10 Mbps). Setup was a breeze as I only had to call RCN and provide the serial number. Hopefully the modem lasts many years as my previous, older Arris models.

We upgraded from a 3.0 to this 3.1 and our internet speeds almost doubled so I highly recommend this!

Very fast and reliable. Highly recommend to anyone with small house or business.

asy setup & works gr8. Compatible with Xfinity/Comcast, which is y I bought it, as the previous model was no longer supported. Def recommend Arris...old reliable from when they were Motorola! Never an issue & this is my 3rd upgrade over a period of prob 20+yrs!

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.
