Customer Ratings & Reviews

Coverage is good. Enables us to have better internet connection at home.

Less than 6 months old & modem is dead. No problem, it's under warranty. Yes, problem. I had to pay for shipping of replacement and it took 5 days to get to me. Terrible customer service.

This modem/router combo drops connection on a daily basis. Arris’ consumer tech support/customer service is nonexistent. My ISP has informed me that it needs a firmware update that has to be completed by Arris, but Arris’ literature on the item states that they are unable to perform this update, it must be done by the ISP. AVOID PURCHASING AT ALL COSTS you will be plagued by intermittent connections unless you’re able to convince one or the other to actually do their job.

This is straight-up trash. The interface of poor, some of the pages are not even reachable which means some functions are unusable. There is no option for firmware flashing. The speed is ok but the connection drops every now and then. The price is too high for this piece of junk.

The wired ports work almost flawlessly, however the wifi module reboots and drops constantly. It might be best paired with an extender or mesh network, but the modem itself is solid.

Wired connection does provide gigabit speed but WIFI is slow and constantly drops every few hours.

Drops offline almost daily!! When it’s on and running it’s amazing!

I decided to try RCN Gigabit internet and, based on the reviews, purchased the ARRIS - SURFboard DOCSIS 3.1 Cable Modem & Dual-Band Wi-Fi Router. First of all, Internet providers never seem to provide the speed you are paying for. When using a Ethernet CAT7 cable I get between 550-750 Gbps; but when I am using the Wifi I only get 80 Gbps (same room, feet apart from the device). The iOS app ARRIS SURFboard Manager has 1 star at the app-store and rightly so. You won't be able to change the password or the network name using it. It just does not work. I you try to login to the to router via web manager a pop up alerts you that someone is already logged on to web admin and asks if you want to log them off. Once you choose to do so it keeps alerting you that another user is logged on. You have to literally reset the entire router to get back into web admin and still does not work properly. A terrible security flaw. I am returning it today.

I purchased what I thought was the model pictured, A Best Buy phone rep suggested it and I went and picked it up. I tried for 6 days to hook it up, but it wasn't working. A friend stopped by and asked, "Where's your router?" I showed her my invoice and said that it was a combo. modem and router. Then we looked at the box it came in and saw that it was just a modem, although I paid for the one in the picture. Obviously, I returned it. What a waste of time and energy and no internet or TV!!!

Average and okay, one down side is every now and then I have to reset it on the modem.

2.4ghz single continues to stop working after many resets, this item is going back to best buy. You're better better off getting a quality high-speed 3.1 modern and separate router, one that can support WiFi 6 for pretty much the same price as this junk.

Was not consistent enough for our internet needs. Retuned it for another brand.

It doesn't work how it supposed to, doesn't give the speed what I'm paying for

acting very strangely dropping from main connect to guest connect don't understand never had this problem with a modem and router set up

Great modem/router, unfortunately I wouldn’t get great speeds with Comcast

Only issue is that its application accepts a upper case letters when setting up a password. But, the password field does not accept them. They are converted to lower case. A frustrating and significant bug.

I attempted to install this modem with Xfinity. The activation failed. I scheduled a tech to come out and he was able to activate the device on the network. However the wifi and ethernet connection kept dropping in and out. Called Xfinity support, the device would not hold connectivity to the network (wifi or ethernet) after internal file update. Will be returning the device due to hardware problems.

Had issues with speed was told this would help but it hasn’t yet increased any

Just didn't have the signal strength for a 2800 sq. ft. home. Inconsistent signal strength and buffering all the time!

Pretty terrible. Have had it for 6 months after moving and upgrading to 1gb/s speeds from my provider. This modem/router has been junk from the beginning. It’s range is terrible at 50 for with 1 hollow wall in the way. The connection drops CONSTANTLY! For this price, it should work 10x better!
