We tried several modems advertised as XFINITY Comcast compatible but could not get them working

Comcast blames the router, router support blamed comcast.

Comcast were unable to get Motorola tech support on the call.

Replaced a 12 year old Comcast modem, which failed.

The cheap Comcast gateway had 4 times better range than this thing.

My comcast provided cable modem stopped working properly

Since Comcast doesn’t guarantee a minimum speed I didn’t even want to call them and deal with their nonsense and it will pay for itself in a little over a year

Since its my equipment, Comcast wouldn't support the product.

I finally cornered a Comcast IT guy, and he confessed that their leased routers have known antenna issues, and they have lousy throughput speeds in my area

The set up went pretty smooth once the right comcast tech. got on line

Here are a few examples :https://gigaom.com/2013/02/07/more-bad-news-about-broadband-caps-many-meters-are-inaccurate/https://www.dslreports.com/shownews/Users-Still-Complaining-About-Inaccurate-Comcast-Usage-Meters-137815http://arstechnica.com/business/2015/12/comcast-admits-data-cap-meter-blunder-charges-wrong-customer-for-overage/With the rise of cord-cutting and video streaming services such as Netflix, Playstation Vue, Amazon Prime, Hulu, sling TV and others coming in the near future, this is going to be a problem

I've had countless types of WiFi routers in my house, and even the one that came with Comcast worked well

The annoying and infuriating Comcast intermittency still happens, but the gateway has a very short startup sequence that minimizes the duration of the dropped service

On it’s worst day, this router works at least as well as our old Comcast rental did on its best day

I am struggling to get out from under our expensive comcast/xfinity addiction and I am starting to pare down the bill by getting my own equipment.

Think it works better than the one Comcast provided and definitely worth getting rid of extra fees renting their equipment

Had issues with Registration but that Comcast's fault due to a mixup of my account

I've been hating Comcast for years because of crappy service; this seems to have fixed my problems.

Not as great as it said it would be

when the router works it seems to work as it's supposed

The unit works as i expected it and i recoment to everybdy
