Details of wpa_supplicant.conf

do I need the “” yes or no besides de SSID & password?

You need double quotes (") for ssid and psk values.


country=DE 
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev 
update_config=1 
network={
     ssid="WLAN SSID"
     scan_ssid=1
     psk="WLAN PASSWORT"
     key_mgmt=WPA-PSK
}

Thanks. Now I conclude that there’s something wrong with mij Rasp4. Tried al 4 combinations, but there seems to be no device “Raspberry” or somewhat. Or do I have the wrong interpretation of the output?

192.168.0.169 is the IPv4 address of the RPi (at the time the picture was taken).

Right. In simple mode of my router its name is Raspberry, in advanced mode the IP name is “UNKNOWN” (the IP is a reserved adress), but the Raspberry seems not to “see” wireless modules.
Reactivating (enabling) Wi-Fi with ha network update wlan0 --ipv4-method auto --wifi-auth wpa-wsl --wifi-mode infrastructure --wifi-ssis "TP-LINK" --wifi--psk "MY_PASS results in
``Error: unknown flag: --ipv4-method auto `
My mobile cant find signals FROM the Raspberry either.
