Using an external USB wifi adapter instead of the built-in one

[dhry]

When using the internal Pi wifi, we set

LAN_WIFI_DRIVER="nl80211"

But what if I want to use an external USB wifi adapter (currently wlan1, but if I disable the built-in and reboot it will become wlan0)? How do I find the correct value to use for the LAN_WIFI_DRIVER parameter? I guess I'm asking if this even needs to be changed if you want to use a different adapter?

Plugged in the dongle and have a look to the detected hardware then on google you should find the information. That's specific to your dongle.
You can keep wlan1 or else try to install all for your dongle first and then apply the script with expected correc tvalues
