    Easily connected to my internet provider, no calls just follow the on screen tabs. Always on, never have to reboot. I guess I’ve had this modem for month now and it has been working like I expected.

    Upgraded to this modem for Cox high speed internet and everything from installation to setup was made incredibly easy. Essentially plug n play. Using it with a Netgear router for weeks now without any hiccups or reboots.

    Was having troubles with my internet connection. Narrowed it down to both some cabling and modem problems. Optimum repaired the line and I replaced the modem. Have fantastic download speeds now. Would highly recommend this one plus you don't have to pay that monthly rental fee to the cable company.

    DOCSIS 3.1 is worth the upgrade! Along with a faster speed tier from Xfinity, this works great. Only had for a couple months so can't attest to the durability of this modem but so far so good.

    As a Comcast subscriber, I decided to forego renting their cable modem and purchase my own - at the time, it was the only 3.1 Docsys equipment available - great speed and easy to set up; very pleased with my choice!!!

    I originally bought a Arris mod cause I recently upgraded my internet to 1000mbps. Turns out that modem wasnt fully supported by Xfinity and the quickest i got was 600. The netgear was supported So i swapped. Never looked back since. Its kinda nice to see the speedtest hit 900-1000. The only downside is that it only has 1 ethernet port and its not wireless. But that im a gamer so i knew what to pair it with. I paired it with the new wireless router Netgear Nighthawk RAX80 with the new wifi6 standard.... totally recommend these 2

    I have not had this modem very long; probably five or six weeks. I am pleased with the performance but I must add that I generally do not put much stock into a review of a product that has been in use for a short period of time. I would rather hear from somone who has used an item for a year rather than little over a month. While I am pleased with the performance to date I also think the product cost more than it should have.

    I replaced my ISP-Provided router with this, and my internet has been a lot more reliable. It also uses significantly less power than the old one and kicks off less heat.

    I bought this modem to make an upgrade to gig speed internet at home. Setup is a breeze and you’re ready to go with a high end product you’re not renting from the service provider.
