Comcast Is Turning Customer Routers Into Public WiFi Spots

Are you a Comcast or Xfinity customer? If so, there’s an exciting new initiative Comcast is trying to make you be a part of without asking. Namely one where, if you’ve got the latest version of Comcast’s WiFi “gateway,” you’ll not only be broadcasting your own private signal, but a public one! That any Comcast subscriber can use! Without your knowledge!

The idea is actually a pretty good one, in its own way. If you’re a Comcast subscriber, you can just ping the area and use public Internet wherever you are, as part of the Comcast neighborhood node program. But Comcast makes a few claims we’ve got to look at with skepticism.


"This signal is completely different from the signal that subscribers have in their home. This means that if customers subscribe to a 50Mbps broadband service, they will have full access to that speed and capacity, without any interference or degradation in service from the public Wi-Fi portion. “Our broadband customers will continue to get the service that they are paying for,” Tom Nagel, senior vice president of business development, said in an interview. “That was extremely important to us in designing this product.”

If the latest version of their routers are really two separate routers, that makes sense, we suppose. But the whole “this won’t compromise your service” claim is a bit like Comcast arguing that Netflix is from the grubby “public Internet” while their own streaming service is from a magical land of elves and fairies. It may be two separate routers… but it’s the same cable serving both groups, and if, for example, you’re broadcasting a connection in a fairly public area, it’s difficult to imagine that not causing any problems whatsoever. And, of course, there are concerns around security and privacy; this being Comcast, somebody figuring out how to hop onto the better connection and maybe steal your credit card numbers while he’s at it is a matter of when, not if.

Fortunately, you totally have to sign up for this. Just kidding! It’s an “opt-out” service, so this will just be flipped on if you have one of these “gateways” in your house and you have to tell Comcast to stop it. We might recommend buying a “router,” which will be both cheaper in the long run, and less prone to being called ridiculous things like “gateways”.

If the signal that is being broadcast is completely segregated from your connection in both content and bandwidth, I really don't have much of a problem with it. I think it's a low tech and high risk method of delivering wifi.

Only applies to people who use the modem/router in-one type box from the cable company. which is stupid, IMO.

My wonderful DSL company requires you to use their all in one box. Which is nice and spiffy and has a fun little glitch where the wi-fi is suddenly disconnected from the internet (hard wire is still fine). Still have signal, still have DHCP and DNS settings, just no internet connectivity... until you unplug/replug in the router. My annoying solution, plugging in another wireless router to that POS.

Bought my own routers and modems for both houses that have comcast. Cheaper than renting over the cost of a year.

Semi-related - I'm signing up for Comcast interwebs this week, as it's my only option in the area that we're moving to. Any suggestions for a cheap modem that is compatible with them?

Here Comcast requires you have a modem with their router, if you have their voice service.

Will the FBI or RIAA still come after you if someone uses your free Comcast wifi to do something they don't agree with?

I think I would have a problem with this. Mainly because of bandwidth.

I understand that Comcast is separating bandwidth between the subscriber and the leecher, but all that tells me is that Comcast has extra overhead on their cable line that they're not giving me the option to use.

Wait, so comcast is going to let me use other people to pirate content? This seems very open to abuse.

Why wouldn't you buy your own cable modem/router to begin with?
Last time I checked the rental fee was $7 per month or $84 per year.
You can buy a cable modem for $60 and own it.

From the article quoted in the OP, it sounded as though you have to be a Comcast subscriber to access the "public" wifi. That would mean no anonymous connections, right?

Can't if you have their voip service. At least I don't know of any commercially available units that also provide that service.

So, if Comcast were to reinstitute bandwidth caps you could just use your neighbors wifi? Or would they be able to monitor your bandwidth thru other peoples routers?

Yeah, this sounds like it was completely thought out. Just like Windows 8 and the new Xbox.

A client of mine just had comcast business internet and phone system installed last week. When I went in to install her computer and POS system, I looked at what they had installed. 3 cable modems! 1 for phone, 1 for her internet, and 1 hooked to a wireless access point for providing the free public wifi!

This could explain why Comcast has not reinstituted bandwidth caps. It would be pretty hard to argue for the caps when they apparently have enough bandwidth to add the free wifi, which would allow people more access to their system and use more bandwidth.

So, if the free wifi keeps Comcast from having bandwith caps, I say great. After all there is no way it will be broadcasting from my house.

One would assume there is a web login, etc. That way they can track what subscriber is doing what.


I'd be very nervous about opening my network to anyone though. I just don't trust comcast to do it in a secure method.
