Yes, that is why I've been passing ant_sel=1 during my tests -- this
was needed to achieve a good performance in the past, before this

antenna cable is plugged to the connector labeled with "1" on the
card.

What is the recommended way to monitor the signal strength?
Thanks for such a quick reply,
