DO NOT attempt to move a file over WiFi onto the Toshiba Air Card that includes an "&" embedded in the file name. Example: "Nuts&Honey".

Windows is fine with this, and the file system on the SD card is fine with this, but the Toshiba code that deals with comms to/from the card goes bats. I seem to recall that DOS utilized the "&" as kind of an "Escape" character, maybe something like that is going on... Anyway, the file save will fail, and the card's "Files" directory will become inaccessible via WiFi. Take the card out and directly access via some SD dongle from your computer to change the filename to one without the offensive "&". All will be well.

I feel like a freaking idiot for not approaching it from the "What was the last thing you did" perspective. Took me about 30 minutes of ripping things apart and incrementally rebuilding it all to get it. I finally got the (in your face) clue when I saved the same file I had been trying to save previously, and everything promptly went straight south in a handbasket once again. Faceplant...
Holy crap that's messed up, It would've taken me days to figure that out.. I've switched both of my printers over to OctoPrint so I've not used the cards in my printers for about 6 months now.
