Now the most obvious problem shown in journalctl seems to be authentication.

One report on the web suggested that certain characters in passwords

I use is a period (.), which according to all reports I can find is
legal for ssid passwords.

I have a period in my SSID pasword and all my Pis work fine

When building a Phoniebox for one of our grandchildren, I learned about the "wpa_passphrase" command. It generates a 256-bit PSK from the SSID and the ASCII passphrase and dumps it as a hex string, eg
$ wpa_passphrase abc defghijkl
network={
         ssid="abc"
         #psk="defghijkl"
 psk=6db784a0ea8130c5ff07e690923f9af50cfea5c0776b607bea9bc4478c41f8dd
}
This should
a) get rid of any special character issues
b) speed up the connection establishment.
I successfully tried it on my kubuntu laptop as well.
