Hey Terry.
At first I want to apologies you for the time that you have to wait for response. It’s my fault so please don’t blame other members of my team.
We understand what the problem is. Now we are working on it to fix this issue. Until this time, temporary solution is to hold reset button on CORE2 until ASUS Tinker Board will boot themselves (LR2 led will turn on). About your latest post I thing that the best trial to make sure what’s the problem is connect Tinker Board to Screen and check if both computer are in the same WiFi wireless.
Regard,
Hubert.
