Captive Wi-Fi has changed at cafes and businesses. My experience is, Starbucks blocks local hot-spots. You're forced to use their Captive Wi-Fi and only their Wi-Fi. This formerly wasn't an allowed thing.
Are they mining data? Does this promote some ambiance? There's probably 3 different answers, and you'll normally hear 1 is the reason.
- zoky 8mo agoHow do they block them? The only way I can think of would be signal jamming, which is super illegal and would have the FCC on them like brown on coffee beans…

- eddythompson80 8mo agoWhat’s a local hotspot and how does Starbucks block it? It’s illegal to jam signals (assuming a “local hotspot” is some Wi-Fi network from a neighboring business or center?)
- stackghost 8mo agoIt's using your phone's "hotspot" feature to get your other devices online without signing into the wifi. Modern smart phones have this built into the OS. The phone broadcasts its own SSID and the laptop or other device connects to that, and then the phone acts as a router with its own mini NAT and DHCP stack. It can be blocked because the wifi equipment at the cafe can see multiple MAC addresses emanating from one client, among other techniques.
- eddythompson80 8mo agoThat doesn’t make sense. Why do you care about the wifi equipment in the cafe if you’re connecting through your phone? The cafe’s wifi isn’t even in the loop.
- coro_1 8mo agoWhat I meant is that I’ve noticed cable-provider hotspots often stop working inside cafes like Starbucks and you can reconnect to them as soon as you step outside.
- stackghost 8mo agoIt's probably more to do with QOS algorithms. Unless you're not browsing TLS-protected sites there isn't much data to mine. Wifi eavesdropping is mostly a solved problem these days. If starbucks could MITM your wifi connections to mine data we'd have bigger problems.
