Adding WiFI adapter for shore connection

[MilesAhead]

To me it looks like your Pis internal wifi, wlan0, is connecting to your home network when you want your tp-link usb wifi to do so?

The only error I see is i think you should set ‘sharing internet device’ to wlan1 not wlan0

Give that a try and report back.

When I click "Apply" after setting 'sharing internet device' to wlan1 I get an error message: "The device you want to share is in use (bridge or AP)"
