Well I did that and when I connected I had a wlan 0 and a wlan 1
I assumed the usb was wlan1.
It connected as same but it also added a a available connection for wlan0.
My ssid is hidden and with the internal it always failed.
When I added the usb dongle it still failed when I used wlan1 but eventually it was added after a while by itself and shows it connected but it also added another wifi network with the ssid on wlan0 but it shows not connected.
