Reconfiguring wlan0 for new WiFi connection

[ImanolGo]

I've tried the ap_sta_config2.sh on a Raspberry Pi 4 with Raspberry Pi OS Bullseye.

It doesn't work out of the box, but after a couple of tweaks, it's able to configure the device and after reboot, the AP is created as well as the internet bridge with the STA.

However, if you would like to reconfiguring wlan0 for new WiFi connection, ie, using:

wpa_cli -i wlan0 reconfigure
sleep 10
ifconfig wlan0 down # better way for docker
sleep 2
ifconfig wlan0 up # better way for docker 

It looses completely the wlan0 connection. Anyway, using:

wpa_cli -i wlan0 reconfigure
sleep 10
ip link set wlan0 down
sleep 2
ip link set wlan0 up

Seems to be working. Is this something that you have tested?

@ImanolGo : Could you please tell which changes you made to make it work?

I am trying to use the script on a Raspi4 with Debian 11.5 (bullseye) and the script seems to work, but in AP+STA my new AP is not visible.

RPi4 is connected via LAN cable.

./ap_sta_config.sh--ap NewWiFi newwifipassword --client ExistingWiFi wifipassword --country DE --no-internet

AP + STA configurations are finished!

--> You MUST REBOOT for the new AP changes to take effect.
