I follow all the instructions to set up a personal hotspot on my iPhone 6s using wifi. The iOS is 13.4.1. The phone shows up on my laptop as an available network but when I connect it says “can’t connect to this network”. I tried using the USB method and it worked once but has not worked since. It says “your device is connected but you might not be able to access anything on the internet”. Network status shows Ethernet 2 Public Network. But internet doesn’t work. I have 1 gb of data on my phone so that’s not the problem.
