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: Great modem/wireless router combo! - This is great replacement for my older motorola surfboard modem/router combo that I got back in 2011 to use with spectrum. It was older docsis 3.0 and needed to be replaced. Also easy to call cable company and have them enable it. The gateway menu options are similar and easy to navigate and wireless network setup is easy. The firewall now allows for other devices on my network that require other (different) ports. Before I had to keep setting on low (all ports opened) but now I can keep on medium for more safer network. Works great with 1gb network ports with cat 6 and wifi 1gb (current ISP is about 400gb). No issues with it so far. Love it! ## Features - A Trusted Name in Home Connectivity: Get high speeds, low latency, and a two-in-one product.

Right away Arris had “cloud” issues when i had to call to finish the set up. My tv now has grainy pictures and the streaming aps load slowly. Cant use YouTube at the moment. I regret purchasing this over priced piece of crap. Small apartment and it cant reach all the rooms. I waited too long to set it up so now i cant return it. Huge waste of money. ## Frequently Bought Together - ARRIS (G18) - Cable Modem Router Combo - Fast DOCSIS 3.1 Multi-Gigabit WiFi 6 (AX1800), Approved for Comcast Xfinity, Cox, Spectrum & More - Roku Express 4K+ | Roku Streaming Device 4K/HDR with Voice Remote, Free & Live TV --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/731569870-arris-g18-cable-modem-router-combo-fast-docsis-3-1](https://www.desertcart.us/products/731569870-arris-g18-cable-modem-router-combo-fast-docsis-3-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-18*
