I think that the OS attempts to remember previous settings so that might help. That’s what fixed my error before. You might want to try reloading the image on your USB key and seeing if it wo9rks from a fresh install while wired. If that doesn’t work, try a few more times and see if it fixes itself — believe it or not, that worked for me when I ran into an error after my one crash.

If that doesn’t work… could be hardware. Try your regular laptop and see if it makes a difference. At least then you can rule out a bad image flash…
