I would like to disable WLAN altogether on the gateway
Currently set in Wifi client mode (I also have a cellular and ethernet connection to access router)
For security purposes, I would like to disable the Wifi on boot and just use cellular/ethernet.
I tried doing this by disabling the service
systemctl disable dbus-fi.w1.wpa_supplicant1.service
but wifi still comes up. I notice there are some custom scripts called at start from
/etc/rc.local but couldn’t find a simple way to disable wlan0 coming up.
Any advice on the most compatible method to prevent wlan0 starting?
