Funny coincidence. I've just spent the last hour on the phone with Comcast support asking them to disable the "xfinitywifi" my router is broadcasting and when it was all over decided to unwind and read some NH... And see this! For anyone who needs to, call "1-855-845-6834" and ask them to disable the "xfinitywifi" hotspot on your router. This will save you the 4 transfers, giving your info many times, and listening t…
This looks like a step toward what is variously called "hotspot 2.0" (Wi-Fi Alliance)[1], "next generation hotspot" (Wireless Broadband Alliance)[2], and "het-net" (4G Americas)[3]. The problem is the exponential growth in demand for cellular bandwidth. Its very expensive for the cellular industry to increase capacity by building new towers. So the idea is to get consumers' cellular devices using wifi data connection…
Does anyone who have this (or any of the other similar systems) know if you the other people go out with your public IP or not? If so, comcast/bt/bezeq has just killed all association between ip and identity (not that there was much to begin with, but there was)
BT runs three SSIDs. Your network, BT-Wifi (FKA OpenZone), and BT-FON.
Your network is your network. Private IP, different encryption. The packets leave your house, travel over the ADSL, exit the DSLAM, into a BRAS. There (more or less) it exits onto the "internet" connectivity of BT, with the IP of your ADSL modem.
FON and BT-WiFi leave your house, travel over the ADSL, exit the DSLAM, into a BRAS, but there's a difference now. Instead of exiting onto the "internet", it is stuck in a channel that goes to a different part of the network. This part hosts the server where you login/etc. and where your traffic eventually leaves, with a different IP address than the home network, to the internet. I'm fairly sure the IP is a proxy address, assigned to the logged in user's session, and not tied to the specific router. That channel used to be 256kbps reserved. I think it is now 512kbps. This channel has lower priority than your normal internet traffic.
There is also another channel for BT Vision, that IIRC has 2Mbps reserved for their video. I assume this never leaves the BT network for the internet :-) This has a higher priority than your normal internet traffic (for obvious reasons).
AFAIK the BRAS is where the quality of service is enforced. The router is requesting the different classes of service though, and is tagging the packets. (And I think it's also running a tunnel for the FON and BT WiFi).
EDIT: Corrected a mistake, added some clarity for other q's raised elsewhere.

What's your objection to this feature?
Second, the way I see it, Comcast is asking us to donate our resources (bandwidth, etc.), as minimal as they may be. Now, I don't mind donating to a good cause. I do, on the other hand, mind being forced to do so, without my consent; and especially so when a company is profiting from it ($3 daily access pass for non-subscribers).
So, if (a) I could be sure that it will not affect me, and (b) this would be a free for anyone who is in the area to use, and (c) they'd ask me to opt-in, I'd enable it.

Interesting. Any idea why AT&T can't make their hotspots around nyc not suck? I'd love to use them to save data, but I end up disabling my WiFi just to keep my phone from auto-connecting and then not functioning.

In short, at BT, no way. Your IP is your LAN. Other users get different IPs. BT runs three SSIDs. Your network, BT-Wifi (FKA OpenZone), and BT-FON. Your network is your network.

The TV side of this can be found by searching TPG IPTV and FetchTV, but on the whole we don't have enough bandwidth for this to be deployed successfully.
Where you say 2Mbps reserved, is this set up in the router as a separate virtual circuit? In this case, does it make a hypothetical 20MBit connection 18MBit to the end user?
I have an Xfinity Wireless Gateway, and I see no visible networks named "xfinitywifi" nearby.

;tdlr it degrades your security, and is generally annoying.
