Q: Does this modem include a built-in WiFi router?

Q: Why should I buy this modem instead of renting one?

Q: How many ethernet ports does this modem have?
A: This modem has one Gigabit Ethernet port.
Q: What is the DOCSIS certification of this modem?
A: This modem is DOCSIS 3.0 certified.

A: Yes, this modem is compatible with Xfinity from Comcast.
Q: What is the maximum internet speed this modem supports?
A: The NETGEAR CM700 cable modem supports speeds up to 1.4 Gbps.
A: No. This is just a cable modem. You will need a wireless router to pair with it. Make certain any wireless routers you may have but are not using are turned off to avoid a Double-NAT issue (which essentially means you are broadcasting two wireless networks on the same IP from your Internet Service Provider). If you already have a modem/router combination running (it seems to be standard issue to install them in the States now and charge customers monthly leasing fees), make sure to contact your service provider and inform them that you will be using your own cable modem and/or wireless router so they can place the one they gave you in Bridge Mode to avoid a Double-NAT issue. I'd also recommend turning in any equipment you are not using to avoid paying monthly fees and just use your own cable modem and wireless router/mesh system, Hope this helps.
Q: Will this work with comcast phone bundled system
A: I bought this modem for myself and my son who also has Comcast bundled services. It worked just fine with Comcast, met their requirements for a modem and it increased the internet speed that he received.

Excellent modem. Seems to work great with my NetGear Orbi mesh wifi system. Provides a strong signal throughout the whole house. I get a consistent signal as my internet provider claims (400 Mbps). I'm very happy with both NetGear products. Note: this modem is for use with a cable provider like Spectrum in my case. This will not work for fiber or dsl system providers).

Best Buy was super helpful in knowing what I needed. The Netgear Cable Modem is super fast and easy to set up. I now have a couple of home wifi setups that will extend the Netgear Cable Modem. Great price too. DOCSIS 3.0 matches Xfinity.

I expected 2 things: 1) A nighare trying to get it provisioned on my ISP network. 2) I was going to lose speed because it wasn't their product. Wrong on both counts. Setup was very easy, no issues with cable company, and after checking the bandwith, it was the same as I had prior.
