    Motorola - 32 x 8 DOCSIS 3.1 Cable Modem

    Purchased this modem as a replacement for a similar older version Motorola cable modem. The old modem was several years old, I believe it was purchased around 2014. That is why I wanted to purchase the newer model. Easy to connect and quick to connect after calling cable company. It took longer to have the cable company setup the modem on my account than it did for me to connect the modem and for it to come online after added to my account.

    Quick, easy straightforward setup and install but had some kind of firmware problem and disconnected from internet but from Comcast viewpoint it appeared to be on and connected. Replaced with a DOCSIS 3.0 modem and no problems.

    Leaving a four star review because as far as I know this is a good modem, but it won't work with my internet provider. Be forewarned-if you have Rainier Connect, it no connect. Other than that, it turned on fine, kept trying to connect even when it couldn't, and it looks much better than the modems that my ISP actually has approved.

    Bought this to replace a NetGear modem/router combination that wasn't giving me anywhere NEAR the speeds I was paying for from Xfinity. Once I bought this modem and I paired it with an eero mesh system. I'm getting speeds over 700Mbps, which is more like it. Has been working great so far. I'm glad I switched!
