## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Easy to install
  

*by A***. on Reviewed in the United States on January 17, 2018*

Easy to install. Just plug it and you got the code of the WiFi in the box. Use it on Xfinity. Great speed. Love it because it's small and powerful, not like the huge boxes they have for renting.

### ⭐⭐⭐⭐⭐ 







  
  
    A reliable low-cost modem/router
  

*by G***. on Reviewed in the United States on July 1, 2019*

I bought this modem/router to replace my spendy and out-of-date leased version from Comcast. It works perfectly, even in an apartment building with many strong signals on adjacent channels by competing Wi-Fi neighbors. The interface with the Arris software is very useful if you need to tweak the performance in a dense Wi-Fi environment, like assigning a specific channel over interfering others. This unit was brand new, although it was made a few years ago, but I have had no problems and recommend it to others seeking a low-price replacement modem-router.

    works great for time warner/spectrum users, recommend
  

*by X***A on Reviewed in the United States on October 8, 2017*

I've been with Time Warner Cable (now Spectrum) for over a year now, and during my first year I was leasing an Ubee modem/router from the company any paying the $10/mo lease. After my first year my bill jumped up, and obviously I should have just bought my own modem/router from the beginning, but what can I say? I was young and naive back then. After spending weeks trying to figure out the best plan of action (do I buy a modem and a router? should I get one that has wifi built in?) I decided to go with this one. I live in a small apartment and it's just me and my boyfriend who use the wifi on our phones to stream to the google chast on our tv, and after installing it yesterday (very simply and easy) it's been running amazing! I was a bit concerned at first because this is a very small modem, and it gets warm fast, but nothing a little fan can't fix if it ever gets to that point (I mean, do these things overheat like a laptop? probably not). Anyway, I'm returning my stupid leased modem back to time warner today and couldn't be more excited! I recommend.
