The Pi has an ethernet connection, so just out of curiosity I tried booting with a cable attached to my router. The cable lights up, so I know it is detected, but the Pi-Top boots part of the way, then turns off.
I haven't checked the logs yet, but I suspect that the initial scripts are looking for a wireless connection.
Can anyone offer any suggestions? This is hardly a game stopper, but I want to test the limits and see if there's a quick work around.
By contrast, a USB mouse is detected and becomes functional without any difficulty.
If you plug in the ethernet after logging in, you can use it freely.
Did you have to modify your case to connect the Cat5 cable? On mine, I can't even see the ethernet port from outside the case.
