This might be a final fix for GitHub issue #173 and possibly others: ACTIVELY detect borked port status on Windows and if any "cable unplugged" or other wacky states are detected whack the adapter (close and reopen). Tested adding a whole bunch of windows networks, removing, adding more, etc. and it seems to work very well!
