    We did a ton of research to see what modem would work with our new speeds and help around the house. Ended up with this guy. The setup was super simple and had no issues the first day. The next day the internet started dropping every hour or so and required a modem reboot. We did this for a few days before ultimately returning it and going with the surfboard one compared. We haven’t had an issue with it at all!

    So far, so good. It meshes well with EERO Wi-Fi Router. It’s reliable and fast. My download speeds are consistently maintained at 1200 Mbps. To give you a better idea we usually run on average 33 devices daily. Installation was super fast. Very affordable!

    This works well with Xfinity Comcast. It’s easy to setup but you’ll need Xfinity app or call them to activate. For the speed, I get over 1 gbps no problem. It’s bit pricey but no complains here.

    Easy to install and activate on my Comcast website. Gained approximately 30% more internet speed when coupled with my ORBI system. Nice front design with several status buttons to alert the user to its status. Very Happy!

    Had this modem for a few months now after doing some research as it is rated as one of the best modems for spectrum and xfinity. However, it has randomly disconnected at least 3 times while I've been gaming at the worst time getting me kicked from matches. I thought it was spectrum at 1st but after doing more research it seems to be a problem with this router. Luckily I purchased the warranty and I'll be returning this to get the arris s33 modem. It was good for the most part but I need stability especially for the price of this modem.

    Did not work well with Optimum internet. It kept resetting itself every hour at random. Optimum couldn’t do anything about it. Returned the modem and bought a Arris Surfboard and have had no problem. I’m sure this modem is fine with another Internet provider.
