iPhone WiFi hotspot drops connection to my Linux laptop every 10min or so

I used to always tether my iPhone for internet access on the go, however since the ios 14 update that stopped working. This is being dealt with by the Linux community;

github iphone tethering issue

Since USB tethering was not working i've had to resort to wifi hotspot instead. This connects just fine and works fine for approx 10-20 min. Then the connection drops and i have to toggle wifi hotspot on the phone to get it to re-connect.

Works fine with other devices, for instance android phone.

I tried running a script to repeat GET requests to a web page to keep connection alive but even this failed.

Any idea whats causing this?

Laptop is running manjaro linux, also affects ubuntu linux.
