I know this is a simple thing, but its one thats easy to forget, anf you can find yourself in a bit of a pickle.
When you have entered a service-module session, for example connecting to an integrated access point, and you would like to disconnect and return back to the router, press Ctrl+Shift+6 then x.
You won’t see any output when you press the first Ctrl+Shift+6. When you press “x”, you’ll drop back to the router session.
The session to the service module will still be active in the background (use show session to see). which means when you hit “enter” on an empty router line you’ll return to the service module session.
Type disconnect to close the connection.
