I am using elementary OS 6 on PC. When I plug in my iPhone SE to PC trough usb cable and turn on "usb only" hotspot network station bounces/switched/glitches from "connected" to "cable unplugged". However stable connection will be established after several minutes. In my case I unplugged/plugged the phone then switched on/off hotspot and I did it non stop until I have a connection. Maybe connection will stabilize itself without intervention. Notification area also bounces from "connection established" to "connection disabled"
