    Very Fast Cable Modem

    I needed to upgrade my old cable router after my internet provider upgraded me to 1GB service. I have tripled the speed of my previous cable router. I did have to call my service provider to connect, but it was easy one I got a service representative. Very happy with this cable router. Should last me for a few years.

    I bought this modem to replace my previous DOCSIS 2.0 modem. Wow, this modem is so much faster. It's located in my Garage and subject to warmer and colder temperatures then inside my house. I haven't had any problems but I do occasionally reboot the modem, switches, and access points every couple of months as a best practice.

    I upgraded to this modem to this modem because of the DOCSIS 3.1. It gives me much better speed on the internet. My system speed is supposed to be 150 Mbps. I was only getting about half of that with my old modem. With this new modem I am getting full speed or even a little better. It was very easy to connect although I did have to call my provider to finalize if.

    Its a modem - does what it should. Had to have a Spectrum technician assist with the setup as the automatic activation site says this modem is not supported. (It is supported). Other than that small hiccup for setup I get over the listed 400Mbps download/20Mbps upload speed from my Spectrum service.

    I bought this when I switched to Xfinity as they said I should have a 3.1 modem to maximize my internet. I occasionally had issues with my old unit but this one works well and didn’t want to pay Xfinity a monthly fee to rent theirs when I could buy one for less than 2 years of paying the equipment rental fee. Overall my internet works better but didn’t have a bunch of issues with the 6 year old prior model I had. Just wished upgrading was a little cheaper.

    Beep boop this thing passes data. Honestly not a bad modem for the cost and speed. Stop paying comcast for rental of their junk. Got this paired with the netgear gaming router with WiFi 6, gets the job done for the whole house.

    So far so good, get 1 gig speeds on Mediacom plan. Make sure to call them so they register the device MAC address (as stated in the instructions).

    Was tired of paying the "Renting fee" through my internet provider and decided to get my own. Man has my internet speed improved a bit and now i don't have to pay 'em. Would say to get it if you can. Only down side is that it has 1 Ethernet port to connect your router to as the other goes to the one for the internet.

    The modem was a bit pricier than ehat I am used to paying for aodem, but we were in need on a set up capable of lushing a gig. So far, it gets the job done. I probably would have went with the other model that has extra ports if I had the money.
