good to hear that you found a workable solution with the mini PC
We use wireless connections so much these days, but in most cases we just ignore a glitch - you have to reload a web page that doesn't load, or get a moment of silence on your bluetooth headphones. Unfortunately, astronomy software (SharpCap, ASCOM drivers, etc) was never really designed for a situation where hardware might go missing on a moments notice and then come back again. Even if the ASCOM driver has some sort of retry built in, it can't retry forever so sometimes a glitch will just be a bit too long to be handled by the retry.
cheers,
