    Have had issues with surfboards in the past. Motorola originally made the surfboard, but it was sold off. Now that Motorola is back to making cable modems, I recommend over surfboard

    I selected this modem because it was on the Xfinity recommended list. I connected it as soon as I had Xfinity service at the house. It booted flawlessly and connected to Xfinity service. I had to cycle power on the modem to get my TP Link Deco M5 mesh extender to work correctly - I suspect I should not have connect the mesh extender before internet connection was established. Four months of flawless service.

    Runs very cool....which is a nice bonus. Xfinity person took care of activation quick and painlessly. Links fast with my incoming cable, very fast, very consistent. I have GbE service from Xfinity, and I consistently get ~950 MB on Speedtest. No downside here...get rid of the cable companies modem, this pays for itself in less than a year....and probably performs better, to boot. Very easy to recommend.

    It was all plug & play. A Cox tech was on-site during installation, but all he did was plugging in the modem and power cycle it a few times.

    This has been a solid modem. It handles a Cox 500 plan without any problem. I am pleased with this modem and glad it was on the "approved" list from Cox. It saved me the $600 they wanted me to spend for their new mesh devices which I absolutely do not need.

    I have Suddenlink as an internet provider. This modem is a nightmare at least when using it with Suddenlink. It constantly was losing internet connection multiple times a day even though the lights said it was connected. Suddenlink tried multiple refreshes but nothing would fix it. I finally just purchased a Motorola MB7621 which is a step backwards but has a different chipset. This has been working just fine. Pay attention to the reviews before purchasing this model. You could possibly end up with a lot of frustration. Mine is basically just sitting here as a waste of money because I can no longer return it. I am hoping a firmware update may make it useable one day again.

    I needed a new modem that was fast and met the requirements of my cable Internet provider. This modem was easy to set up. It's fast. Stylish and compact. I highly recommend it if you looking to improve Wi-Fi speeds in your home. We have reduced bufferings on the multiple devices we have connected to our Wi-Fi due to this new modem.
