  • SURFboard DOCSIS 3.0 High-Speed Cable Modem

Q: I want to replace the Comcast wi/fi modem combo unit that i currently rent. What product should I be looking at?

A: I just replaced the Comcast equipment with this and it works great with no issues and setup is just a few minutes and 90% of that is getting the modem registered with Comcast.

Q: Is this modem wireless?

A: This modem is NOT wireless. In researching the best setup, most people seem to agree that you are better off with a separate modem and wireless router than a combo unit, so that's what I did. We have the internet connected via coax to this modem, then connected the modem to a Netgear wireless router with a wired connection. All my devices are then connected wirelessly that way, and we're getting great service.

Q: Is it necessary to call Comcast?

A: After connecting my router to coax cable and to my laptop with an Ethernet cable, I was able to simply open a browser and was redirected to a Comcast page that automatically set it up/registered it. You just need a Comcast login or account information. I was up and running within 15 minutes and never had to call.

Q: can this be used instead of TWC modem

A: That's precisely what this modem is for. I recommend replacing your TWC modem with this one...and saving their $8 per month charge (as I did).

Q: How many wireless devices (phone, tablet, etc.) can be connected at one time?

A: The short answer is none. You need to add a wifi router. The router and the speed of the internet connection will determine how many you can connect. Picture it like a pipe. You can fit more volume (more devices) through a bigger pipe. The Netgear Nighthawk is one of the best.

Q: Connectivity with Airport Extreme

A: It works great! I have my whole network setup with apple products.

Q: Mediacom

A: I have Comcast and I had to drop the phone coverage in order to use this modem. Works great for Cable TV and Internet.

Q: HOW DOES THIS MODEM PERFORM WHEN THERE IS MORE THAN ONE PERSON USING?

A: Yes you do need a router for this modem. The best one I would recommend is the NETGEAR N900 Dual band wireless router with 5 port gigabit Ethernet Switch. It's super great with multiple devices connected to it. I have an Apple TV 2 computers, 2 tablets, ps4 and 4 phones connected to the router at all times and my internet speed is never affected not is the strength of the Internet decreased. This modem along with the router named above are a great pair. Both help increase the signal strength of your internet.
