Hi there
I've got a Samsung Galaxy Tab S7+ Wi-Fi only version and running spacedesk over Wi-Fi works fine but it is a little bit too laggy so I wanted to use the USB Tethering instead.
The problem seems to be that since my tablet is WiFi only it doesn't really seem to support tethering completely. When I connect the USB cable I get the option to select which mode I want to use; 'file transfer', 'midi', 'USB tethering', etc.
But when I chose USB Tethering I do not get a correct ip address on the Samsung NDIS interface that shows up in Windows 10, I only get a link local address (169.254.x.x) and my Galaxy tab can't connect to the computer with the spacedesk app.
If I instead test the exact same thing with my Galaxy S20 phone it works, and the only difference I can find is that when I set the phone to USB Tethering the NDIS ethernet interface gets a "real" ip address in the 192.168.x.x range. And then the spacedesk app connect without problems and everything runs really smooth.
So is there a way to work around this? To make spacedesk work on link local addresses?
(I've also tested the "Splashtop XDisplay" app which seems to have the same problem. Then I tested the "Twomon Se" app and that app actually works on my tablet so there should be a way to make it work)
