Great tech support, quality product.
Great way to save the lease fee Comcast wants to charge. Works great with XFinity Internet. Setup was a breeze. I did have an issue with my wi-fi printers dropping out. I would have to restart my desktop computer for them to connect again. I called Tech support, the gentleman was very knowledgeable and resolved the issue with a setting in the admin section. Printers have not dropped out since.

Works well with xfinity/Comcast
Been using for a over a year for my xfinity internet and haven’t had any issues with it. Plus it saves on those monthly gateway rental fees

Horrible! Just horrible all the way around.
Nothing worked. The instructions are so far off that they were useless. Could not be used with roku sticks or roku tv over xfinity internet. Don’t know if it’s a firmware issue or not since their customer service reps who answered the phone were incompetent, unprofessional and just kept dropping the calls. I had to make 4 calls only to be told to do very basic troubleshooting and then told that it was a roku issue. This was despite the fact that I told the reps that it was NOT a roku issue since I tested the roku devices worked when connected to my hotspot as well as my old modem which was a netgear docsis 3.0. The Arris customer service didn’t even TRY to resolve the issue by going over the settings or anything.I won’t do that again! Overall, I was very disappointed with Arris. I was skeptical of them from the jump. And now I know I should have trusted my gut. Terrible product. Terrible customer service.Save your money and more importantly, your time! It’s not worth it.

should be easier
Day one. I could not get the Arris application to connect it would not find the wi-fi signals, the instructions in the box gave me the wrong IP/address to access the settings, I should have used the old one. I called tech support, they spoke English with heavy accent that was a barrier, just a barrier not a complaint. Reset the modem redownload the app, still nothing. Then he gave me the correct IP/address and it worked right away. Why was this incorrect on the instructions int he box. Got it set up in a few minutes after that. The setting interface is not super intuitive but it’s cleaner and better than the past interface. However every time I connect the setting for the modem it tells me the version of Chrome is old and may have trouble with some settings. I checked, nope Chrome is the newest version and apparently the setting menu is set to run off an older version, but it still works haven’t found any issues. Back to the app. It sucks. You not only have to download one app but two apps. The second app changes your login from admin to your email. Thats a nice touch however I have had to go through the whole process of setting up the app each time and if it works it throws me back to the other app. I don’t understand the reasoning for this. Either way I am hoping this has better connection and speeds looks like it is working once I called my internet provider, Sparklight does work with it. Should have been easier with all the “convenience” options starting with the correct IP/address.

Powerful for personal use.
This router/modem increased the area that my wi-fi reaches which makes me very happy. The customer care was easy to deal with when I had a question about installing. The install was easy enough.

Good performance but parental controls are practically worthless
I used this router to replace an ASUS router that claimed to have outstanding features to support parental control â except that none of the features actually existed.This Arris router didn’t make such claims, but even the ones it made are terrible to implement.⢠The signal is strong throughout the house on both floors.â¢Â I can see the devices that are connected, but the Surfboard isn’t very good at identifying which type of device is connected. Unless you know the MAC address of the device, odds are you won’t be able to identify it. And when you do identify it, you can’t assign a label to it to help you remember/identify it again next time.⢠If you want to shut down a device from 10PM – 7AM every day, that’s impossible to do. You can only define a single time range for each date. You can either shut it down for 10-midnight or midnight-7, but not both.⢠But even then, it doesn’t work. I’ve turn off access from midnight-7, and at some other time during the day, the access is blocked. And after trying to select different time ranges, the only way to provide access was to completely turn off the filter. I thought maybe the device wanted me to convert to GMT, but that didn’t work either.So that was disappointing, as it was the most important feature that I wanted from the router. But as far as I can tell, no router really implements parental control very well.
