I'm surprised nobody has mentioned this in the thread but you can actually opt out of the xfinitiwifi thing. The deal is that you can use any of the hotspots if you have a comcast account and also share your router. If you opt out, you can no longer use the xfinitiwifi hotspots but nobody can use yours either.

I'm using my own modem, so no wifi hotspot in my home, but I've never been blocked from using another xfinity-wifi AP.

If they have that much trouble taking the flags off of people's accounts, it wouldn't surprise me to find out that there's no codified correlation between "has the AP running" flag and the "is running a Comcast router+modem" flag.

It counts it towards your data cap (if you are subject to it), but not to the bandwidth available under your plan.

That's the worst. I have more than enough bandwidth for Netflix, but I frequently hot my data cap. I don't think there is such a thing as a comcast account without a data cap.

For well over a year, my Comcast account has had this note:

Note: Enforcement of the 250GB data consumption threshold is currently suspended.

(427GB so far this month...)

Why would you want to opt out?

xfinitywifi is provided by Comcast, you need a valid comcast login to connect. He is a Comcast subscriber himself, and thus he has a valid Comcast login.

It has not been proven that Comcast has the authority to do this: https://www.techdirt.com/articles/20141208/13222529362/comca... It has been proven that in many places at least in the US, it is illegal and in some cases is a felony. Edit: Further, it is not a good idea to connect to any known SSID unless you know for a fact that it can be trusted: http://arstechnica.com/security/2014/06/free-wi-fi-from-xfin... Your…

What is a felony? Using Comcast?

'chatmasta expects there to be a thread about how to opt out so I'm assuming there's some reason to do it. Otherwise, why would it come up?

Do xfinitywifi hotspots permanently authenticate clients based only on their MAC addresses? A malicious client could easily find the MAC address of any device connected to a xfinitywifi hotspot (by using e.g. airodump-ng [0]) and then spoof that device's MAC address on their own computer to access the internet via the hotspot without any authentication. [0] http://www.aircrack-ng.org/doku.php?id=airodump-ng

That's basically the only way to do it. If it were really clever, it could ignore packets based on vendor extensions and device characteristics. They are not that easy to spoof (you would have to modify the driver, as opposed to just changing the MAC). I actually use this method to use school WiFi anonymously (or rather, as someone else).

Mm not entirely - I'd imagine that they could fairly easily run wpa-enterprise, authenticating against Comcast servers. Then when a user tries to connect, they'd be asked for their Comcast creds, which they could type in once, and then be authenticated with on all such servers.

It's how eduroam works, and that works fairly flawlessly (provided the routers have enough bandwidth).

I just had comcast to my home last week. I pay for 120 mbps but when connected via cat 5 it only reached 90 max mbps which would fine considering when using a wifi router it only reaches around 30 mbps. I have moved around the wifi router but it doesn't make much of a difference. The technician told me the 120 mbps that I am being charged for is for for direct access and wifi won't reach 120mbps. I complained to cust…

It sounds like you just may have a few things to learn about how networking works. Comcast is selling you a coax line into your house and, if you rent their modem, giving you an ethernet interface to it. It isn't making any claims about what happens after that. They can't have control over all your networking hardware and how you configure it.
