You should report this to the FCC if you can find the AP, since it's illegal 
for someone in the US to set a wifi unit to any regulatory domain than the US.

I definitely would find the owner of the wifi unit and inform them, and if they 
were resistant to fixing it, I would have the FCC explain it to them.

Subject: [PLUG] Unable to connect to wifi due to 802.11d - flapping wifi 
regulatory domain

This is an interesting, dare I say exotic, wifi failure mode, at least to me.

I was unable to connect to wifi at home today, and also unable to add anothe AP 
connection.

This did not make any sense to me - so, I spent some time looking into it.
I eventually, connected the laptop to ethernet - I asked Claude Fable, if it 
could figure it out.

After some loose ends, me being very, very specific, rejecting bunch of 
explanations with data - it comes down to this:

There is nerby AP, set in BR regulatory domain (Wi-Fi frequencies/channels) 
broadcasting BR countey code. This caused my laptop's wifi flapping between US 
and BR regulatory domains via 802.11d. So, my wifi saw my US AP picking its AP 
object Id , by the time NM got to connect, the wifi card swithed to BR 
frequencies/channels and the AP object Id was gone. So, it was timing issue 
realy.

Solution: sudo iw reg set US.

I do not think that I have enough experience to have figured this out myself. I 
checked the diagnosis - journalctl supports it as well as google search for NM 
error message: "The access point 
/org/freedesktop/NetworkManager/AccessPoint/NNN was not in the scan list."

I thought, this is worth sharing, not for AI, but as an interesting networking 
issue.
