Review: Solved The Issues - I had bought a new laptop and was having issues that I thought would mean returning it. It would show that I had great connection to the router but no wifi. I constantly had to refresh to make it connect. Thought it was the laptop, but then it started happening on other devices. My old modem was 5 years old. I started thinking maybe that was the problem, so I decided to upgrade that before blaming my devices. This modem was easy to activate through the internet provider's app. Lo and behold - it solved all the connection issues. Devices that connect to my wifi are buzzing along now. So, it was just a case of my old modem not being up to the task anymore. The old modem was also a Netgear. I was pleased with the service I got from it, so when it was time to upgrade I went with Netgear again. Very pleased with the results.
Review: Flawless performer - Title: Performed flawlessly Description: Easy to install & performed flawlessly as soon as I turned it on. Connects to the highest speed offered by Xfinity.

Title: Performed flawlessly Description: Easy to install & performed flawlessly as soon as I turned it on. Connects to the highest speed offered by Xfinity.

### ⭐⭐⭐⭐⭐ Works great with XFinity Internet
*by M***R on April 6, 2025*

It works preety seamlessly with XFinity Internet. While it's rated for up to 2 Gbps, XFinity only rates it for up to 1.2 Gbps on their service (though that may just be them trying to get you to rent their garbage hardware). It has a 2.5 GbE port (which is backwards compatible with a standard 1 GbE Ethernet port on the other end) as well as 2 separate regular 1GbE port that can be turned on for LAGG (requires a device on the other end that understands and is configured for LAGG also) so you can do dual channel if you don't have a 2.5GbE port on the device at the other end (or a 10GbE port and Cat 8 Ethernet cable if you have hardcore network setup). You do have to manually enable the LAGG ports in the settings, otherwise they act like regular individual ports (multiple ports on a modem cannot have multiple client devices connected). Speed on a 1GbE connection is excellent without any overheating or hiccups. It runs extremely stable too, it hasn't had to be reset at all in the > 1 month I've been using it.
