@pfunktyper I was testing this out, and does not seem like NetworkManager has any issues with quote marks.
I think the main issue comes from that in your example:
That’sAllFolks has one kind of quote mark
’, while most settings usually have the straight, plain old quote mark
'. The two are not the same, and if your wifi has one and you set the other, then they won’t be able to connect. (caught it by copy-pasting what you wrote here). So this might be something to check first, can you double check this for us?
What OS are you running on the computer that you use to download the resinOS? Some are more likely than others to change the quote marks as you type. Just a hunch.
So likely you do not need to user and escaping and double quotes around the
psk value, and the images downloaded from the dashboard are correct as they are - they contain exactly the psk that you put in there (including the type of quotes)
