I have spacedesk on a a galaxy tab e running android 7.1.1 using wifi to connect to the network. The primary machine is running windows 10 and is using ethernet to connect to the same network. I do have a couple other devices connected using wifi as well, but I don't think they're using very much traffic.
The initial connection works fine and the picture is clear and updates fast and smooth, but it never lasts very long. Connection is lost usually about about 3 1/2 minutes or so, often sooner. Most of the time the image will freeze on the android tablet and stay that way for another couple minutes before finally giving me the error, but I do get the windows "device disconnected" sound and my main screen will flicker about 15 or so seconds after the image on the tablet freezes.
The error code is 1-2-3-0, with error info 0-3-5-4. Often, but not every time, when trying to reconnect I will get error code 1-0 with info 0-4 and sometimes I will have to close and reopen the android app to connect successfully again.
I know that's a lot of oftens, sometimeses, and usuallys, but if you could tell me some better tests that would help you fix this I would be happy to do them. 🙂
