    Future-proof speeds; perfectly links with Comcast

    Gigabit internet and WiFi 6E are not part of average US home internet setups...yet. A 2.5gbps modem is akin to buying an advanced ticket to Mars on SpaceX. You're gonna be waiting around for a while until it's viable. However, future-proofing aside, it has a practical application. Comcast over-provisions their internet in many cases. So you may get higher speeds than what you pay for by using a more advanced modem like the one reviewed here.

    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.

    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.

    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 the modem and used some best buy rewards. The unit sat for a few months before I had time to find a new mesh router and switch to the new equipment. Worked great for a week then the ethernet port completely went dead (no lights). Multiple calls with ISP and motorola before this was discovered. I was on hold for hours with motorola then got discounted without any support. Took weeks to get a new unit and that was refurbished one not new. Customer service is horrible. Never again.

    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!
