Greatest router I ever bought

The router is horrible and I had to buy another router and bridge the devices so the wifi signal would be good throughout my house.

Comcast did try to say that having my own router might be a problem

I highly recommend a firewall/wireless router with this, as it is just a gateway, but it replaces the Comcast gateway thus saving you $10 a month and eventually paying for itself.

I purchased this router because the Netgear that I had purchased was breaking up on the incoming phone side

How this is considered a 'fast' modem/router, I will never know.

I have an excellent ASUS mesh router

This is a good router modem

So far I love this modem/router more than the actual 1 that was provided by xfinity

If you need a Comcast (Xfinity) compatible router this is the one.

The best modem router combo ever owned.

I would recommend this router to family and friends.

My decision included the fact that I already have a great wireless router and did not need that feature, which other Docsis 3.0 modems now include

Router has no INbound routing capability and very little user programability

working flawlessly so far, no hassles with needing a separate router, works with Xfinity and has increased speed/range of my home network.

Solid router/modem

This is a very powerful router

Because I connected this Arris device to my pre-existing (and slower) wifi router, I just use that older, slower wifi router for wireless

Works with Comcast and has been consistent (i.e., not required periodic restarting), but its range is inferior to the stand-alone router it replaced.

Does not work reliably as a wifi router

Great router- works really well through my entire home.

Bufferbloat on this modem is also minimal if you have a router capable of various QoS settings.

Not as strong as the netgear router I had.

I highly recommend this router for any older router supplying only 2.4ghz wifi.

Great router

This router works great for our home phone, and internet
