> your cable provider already uses your cable modem as a hotspot for other people.

Is this for real? This does not affect me as I use my own equipment, but I still find it hard to believe.

Yes. Xfinity is the big one. Their devices create two hotspots: one for the customer and one to power their Xfinity WiFi service and for bandwidth offloading for their cellular service.

I have to say though as a xfinity customer, being able to get wifi basically anywhere urban is pretty nice

Yea this almosts sounds like it could be a great idea with proper execution, nothing like this in the UK. Imagine if they were upfront and said "well knock a tenner (or whatever is reasonable in the US) if you allow your access point to be used as a hotspot"

> nothing like this in the UK.

It turns out there are several similar services offered in the UK by ISP's like O2, Sky, and BT¹ (recently rebranded as EE-WiFi²) who claim to be the UK's largest WiFi Hotspot Network. Perhaps that's due to it being opt-out on their routers since it was first introduced over a decade ago.

This is actually hotspot rollouts as far as I know though? You dont see BT/EE wifi networks everywhere, particularly not where you'd expect to see a concentration like residential streets / buildings with this kind of system, mainly see BT / O2 hotspots in public spaces like train stations + event spaces.

Tbf may just be less monopolisation of broadband making it more sparse, but they actually have a map of hotspots on that site which implies they are intentionally placed.

Yes. Cox has been doing it for years. They boast citywide hotspot access for all subscribers. I formerly thought that this hotspot network consisted of dedicated APs which they mount and maintain on utility poles in public places. But that’s just the start.

Every Cox customer has a Panoramic WiFi router that advertises as a member of the “CoxWiFi” SSID, and other customers can authenticate there and access the Internet through your connection. This is on a strictly opt-out basis.

I’ve opted-out, and also my router is permanently in Bridge Mode, so there is no technical way for me to provide anyone a WiFi connection. But all my neighbors do, even if they are blissfully unaware.

The best thing about fibre rollout in my region is that the ONT appears to act as the modem so I don't need to set the modem/router into bridge mode any more.

I'm sure that'll end.

Why?

Another reason to use your own Wifi router and modem

Absolutely. Independently of the unauthorized sharing of your bandwidth, ISP gateways are notoriously insecure and underspec'ed. They also have nasty backdoors[0].

Major ISPs in the US have been doing it for at least a decade. Xfinity Wifi [1] claims over 20 million wifi hotspots provided through customer routers.
