There seems to be a bug/problem with the Personal Hotspot on IOS13.
I first noticed it after updating OTA to 13.1.2. After this update the personal hotspot was broken to my android tablet. The Tablet would connect to the hotspot but there was no internet connection. After trying every trick advises through searching google to get it working I decided to try reinstalling 13.1.2 through iTunes. This fixed the problem, the hotspot worked once again with my tablet.. until the next update 13.2.2 which again broke the personal hotspot to my tablet (note: this update was done through iTunes not OTA).
I decided to search online to see if anyone else who is having similar issues with the personal hotspot on IOS13 has found a fix or workaround and came across this

It seems that on some devices ios13 personal hotspot is not sending the IP information to the connected device. I have now manually set the IP up as a static IP for the connection as others have on the link above and the hotspot now works. This is a workaround for now for anyone having personal hotspot problems until Apple finally fix the bug with it .. maybe by 13.4 if we are lucky!

Personal Hotspot not working over Wi-Fi on iOS 13
After upgrade to iOS 13 from 12.4, I noticed that personal hotspot isn't working anymore over Wi-Fi (via USB is ok). Tested on two computers with Win7. The PC can connect to Wi-Fi, but no valid IP...
