[ARS] Comcast turns your Xfinity modem into public Wi-Fi hotspot

Comcast is transforming its customers' home modems into public Wi-Fi hotspots by adding a second signal to each device. In addition to a customer's home Wi-Fi connection, Xfinity wireless gateways (which include the cable modem and wireless router) will by default broadcast a separate signal that other Comcast subscribers can log in to with a Comcast username and password.

Sounds like interference to me.... if everyone in an neighborhood had multiple WiFi, channels will get clogged faster.

I imagine they issue the "guest" network a separate IP and give it it's own network? I would never be cool with some random stranger torrenting from my IP and bogging down my connection. So glad I don't have to use Comcast anymore...

EDIT: I see they claim that it will not use the same network. I still wouldn't be cool with running a public wifi connection from my home without having at least a little control over it.

This has happened in the UK for a couple of years now if you have been with BT. They have a separate WiFi SSID and you can only log on to the public hotspot free of charge if you are a BT customer. Hasn't really bothered me to be honest

I bought my own modem last year to save $8 a month on an item I will have forever.

Will this be a separate signal the modem will receive through a Comcast firmware update or are modems already capable of doing this?

Having my own modem I am wondering what control I have over this.

if you just have a modem them you will be fine as Comcast can't access your router. If it is a combo box, router and modem in one, then you should still be OK as long as you aren't forced to download any new updates from Comcast.

Personally I think this is ridiculous especially given the fact we get terrible speeds for the money. Give me better speeds before you start clogging up my network

Terrible speed for the money compared to what? Comcast is tons higher bang for buck then most DSL connections, which is their main competition.

I guess most lines have a lot of bandwidth available so this shouldn't really affect you... as long as my rated speeds don't go down because someone else is using my line then I guess I can't really complain. I have my own modem with no router though, so Comcast can't mess with me tongue.gif.

Glad I got of Comcast/XFinity years ago and have no plans to ever go back.

LMAO, they'd have a local connection right into your NIC, and it would be an invitation to try and mess with your personal files without accessing the default gateway!

Exactly. There's too much RFI as it is. The reason your microwave can mess up wifi is because they're so close in radio frequency. I wouldn't want to live surrounded by that much radiofrequency radiation.

I would simply demand a standard modem instead, or buy my own instead of using the one they provide. Problem solved.
