I confirm 10000% this is an iOS 15 issue. i have 4 devices iphone 11 Pro, iPhone X, iPhone 12, iPhobe 12 Pro this is NOT a device issue !!!? HOTSPOT worked on all 4 devices immediately prior to upgrade iOS 15 from 14.8 HOTSPOT connects to other device (laptop or computer. Non apple) but shows (NO INTERNET) apple needs to roll out a fix fast. This is absurd.

So I got my new iPhone 13 now. Running iOS 15.1 won’t connect to widows laptop hotspot

Does anyone know if release 15.02 fixed this mess ?

After months of this lame upgrade. Here is what I know. apple is clueless about it. Or they act like it. Bluetooth connection instead of WiFi will run less than 1 MB/sec your only way is USB connection to your laptop or desktop and it works super fast. sadly we have to wait for these apes at Apple to fix it.

I’m on 15.1.1 and now it works !!! 5 months. Apple you suck !!!

To the last poster. Issue is resolved. Just UPDATE your iPhone to the latest OS version in GENERAL SETTINGS
