I have been tethering my home lab from my Samsung Galaxy S9 with easytether. This has worked surprisingly perfect. I have my samsung plugged into an Rpi2 which relays the internet over ethernet to a switch. I wanted to remove the phone from the equation by getting the Pi Hat. The connection is so much less reliable. I have to restart it like every 10 minutes.
At first I tried to follow the tutorials, but they all were slightly wrong with the current version of raspbian on the Rpi 4. They worked but the connection was always shit. Now Im asking for some reference that shows that they work at the specifications they are listed for. Has anyone setup this product to work? Can you share some details?
