Review: INTRODUCING THE ARRIS G20 CABLE MODEM ROUTER COMBO! YOU HAVE FOUND YOUR MODEM! ☑️ - Hello fellow desertcart Prime members! I wanted to give a review on the Arris G20 Cable Modem Router Combo and I must say, this modem is AMAZING! I was doing a lot of research for the past few months because I needed a newer modem to be able to do the things I wanted to do. This modem by Arris offers all that and more! The installation was super easy! I have Xfinity and setting it up through Xfinity app was a breeze! Even though the Arris G20 looks small, it packs a punch delivering robust speeds to the internet with it's Wifi 6 technology! This modem gives you both 2.4Ghz and 5Ghz! The key features I was looking for in a modem was "would I be able to control it through the Arris Surfboard app itself" and it does! I can't begin to tell you all the other reviews I read on other brands and models that people was not happy with! Before buying this model, I had purchased a Motorola MG8702 and it was a fail for me, no network support, no ability to control settings through the app, nothing, lol! Then comes along the Arris G20 Surfboard! You can set up profiles for your entire family and this is really helpful if you have kids! You can set time limits, add their gadgets, turn the internet off and on when you need to and just simple to use parental controls all through the app! All in all, this is a really good modem, you won't be disappointed! Ok, time for some NFL NFC AFC Championship 🏆 Football Sunday💪🏈 Thank you desertcart🥳 Ok, have to go guys! Have a wonderful, safe and blessed day! ☺️🙏
Review: Defective, slow and spotty service - Would not establish a 5G WiFi network. Download speed was 37mbps and it kept dropping its 2.4G signal. Service is meant to be 800mb speed. Signal dropped about every 18 minutes. Was using with Xfinity, it’s recommended by them as being compatible and it’s on the packaging. However, troubleshooting is very difficult because I have to activate the modem through Xfinity, then troubleshoot through Arris. Took several hours to set up. After a day of spotty WiFi on the 2.4G network, I went back to my old modem that’s over 8 years old and spent a few hours re-activating that though Xfinity. The old one works fine. Not sure if this unit was defective or if it’s the product. Big waste of time and not worth the hassle.

### ⭐⭐⭐⭐⭐ Very disappointing with Cox
*by C***G on October 26, 2025*

Worked well for 6 months. Intermittent drops since. The last week it dropped up to 9 times per day with Cox. Oddly it was after AWS outage but all drops were during business hours. Yesterday Cox did maintenance in my area. It's been dropping every couple hours since at so hours of the day/night. Maybe a Cox issue, may be a firmware issue that I have no control over, as I've been told Cox initiates firmware updates. Doesn't matter to me as a paying customer and remote worker who relies on stable Internet for a paycheck. Less than 1 year of owning and an now having to get separate modem router in hopes that will work. Arris-if it isn't you product, perhaps you should not allow Cox to have it as a certified piece of equipment if it does not work as intended with their service because it's hurting your reputation. Very frustrating for consumers with minimal networking knowledge. We want plug and play and based on your description, this is what I should have received after paying for your product. My last modem lasted a few years and even it was not this bad before needing replacement. I do hope all you products are not like this as I'm considering buying a straight Arris modem with a nighthawk router.
