What is xfinitywifi ?

Specs: Win 7
I'm a long-time Windows user. I recently acquired a tablet
computer that runs Android, and know very little about it.
One of the wifi sources it detects is named "xfinitywifi".
It picks up a signal with this name in two widely-separated
locations in Minneapolis. It has no security available.
(No WPA, WPA2, or WPS.)

I have been able to use this signal to access the Internet for
extended periods. Every once in a while a box pops up for a
few seconds saying that I'm connected to Xfinity Wifi. I'm not
connected to it right now and don't remember that the box
provides a link to sign up for a paid secure connection, but I
would expect that it does. My question is: Where is this Wifi
signal coming from? It varies in strength as I move around,
but I haven't been able to localize it. I've only tried it in the two
locations, which are apartment buildings. I'm quite sure that it
is not provided by the smaller building, which only has 18 units.
I don't think it is provided by the larger building either, which has
two Wifi signals named for the apartment building coming from
a Wifi router in the lobby.

Also, why does Xfinity provide this free but unsecure signal?

It appears that this is a free service to Xfinity subscribers.

See this for more information:

All I know of Xfinity is on the website.

Very likely a hotspot similar to many others from the various isp.

They're usually free to access/connect; but some also require you to be a registered user with the isp providing it.

In the UK, Sky and BT (to name two I know of) offer free wifi hotspots around the country to their registered customer.

Freebies usually are found in airports, train stations etc. and of course many department stores, coffee shops etc. Who actually provides them isn't always shown - but often they are provided by Sky or BT or other isp - and the access point may simply refer to the location (department store, coffee shop etc.)

They have a limited connection range; invariably a little slow if a lot of people are using that particular access point. Some may restrict which sites you can connect to; some not so.

One has to be careful when using "freebie" access sites as occasionally they can be fakes; and are actually seeking to access your device and thus personal data etc...

But the one you mention is genuine (at least the name is) so probably OK to use?

Comcast / Xfinity provides cable TV to both apartment buildings.
In the smaller building, each apartment contracts with Comcast
separately, so I wouldn't have expected a WiFi service for the
building, especially since I lived there and never heard anything
about it. I never got cable there, though. In the larger building,
all the apartments get Comcast cable service automatically, so
free WiFi seems more likely. But again, I hadn't heard about it.

In both cases, I can't imagine where the antennas could be
physically located.
