Customer Ratings & Reviews

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.

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

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 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!

Basic, functional and reliable. Easy to install and easy to use. Took 10 minutes to setup... 7 of those minutes was on the phone with the ISP to get the new MAC address setup.

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.

It works. wish it wasn’t so expensive. Hope it lasts longer than my last arris which almost made 10yrs

needed to update old model to obtain higher speeds. everything works well east to set up with cable provider

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.

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.

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).

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!

Great product and easy to install with Xfinity. Recommend this to those looking to own versus leasing from cable companies.

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!

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.

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.

Really good modem for Cox Internet plans, fast, runs a little hot so make sure to have a fan on it if it lives in a cabinet. Typically get 800 MBPS on the Cox 1gig plan.

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!

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