Relax Folks, I am here! Of course, I'm not going to tell you how to fix this, but it will be fixable...
THAT is the unique advantage you have over the poor DJI schmucks.
As well as all that freedom to choose how you operate, (I hope you choose wisely).
Look, I never had a solo before, but I had APM copters and they did that stuff when YOU weren't doing something right.
Keep the thread alive, keep talking about what is happening and what you've tried, and someone like DKMEXR will pop up and give us a hint, or one of you will figure it out. I'm waiting for mine's used go-pro to arrive and the box of old android fones I picked up hoping there is one that will do as a decent and dedicated "screen" before I do any looking into what ails your copters.
At worst as far as I can tell, you'll need to get a network card changed. This is kinda an I.T. problem, rather than avionics..
