Unable to setup OP as wlan client only

[voltdoc]

Hi, new user, thanks for all the great work on this!

RE: RPi4B (powered by a PICAN-M). I tried both the new 64bit and 32 bit v3 images with the same result:

Since I already have an established router and network on board with internet access, I simply want to disable the Access Point in my RPi4V with Open Plotter and set it up as a client instead on my existing wifi network. Normally I expect I would just connect to my wifi using the traditional network client panel in the upper right corner of the Pi GUI, however this indicates there are "no wireless interfaces found".

Mousing over the up/down arrow icon shows:
elan0 down
wlan9 associated with <blank>
wlan 9 configured 10.10.10.10/24

When trying to do anything in the Pi Network Preferences, permission errors trying to configure dhcpcd.conf are all that happens.

Using the OP network app, regardless of how I set the AP Panel (None, etc.) the WLan panel remains unable to be configured.

(Tried to attach screen captures but apparently they are too big)

I am by no means an expert Pi user, but I also noticed when trying to do assorted terminal commands that I use regularly on other systems, that there are many cases of permission denied.

Also when launching an app, for instance 'openplotter-network', it takes a good six seconds before it comes up. Is this normal?

Thanks for any help!

Have you set the wifi country   ?   in sudo rasp-config

Thanks for the reply. Good point, I forgot to mention that above - my attempts to set the wifi country from the GUI always fail. By default this setting is <not set>, I try to change it to US but it never takes and immediately reverts back to <not set>. I did not try from raspi-config, I will do that but not hopeful it will be any more successful. All other localization seems to work correctly. Will let you know, thank you.
