[ath9k-devel] Disabling an antenna

[Jean Schurger]

Hi,

  How can disable  the usage of one antenna ? I've installed an "ath9k"
minipci card in my laptop to replace an intel one that need proprietary
firmware, but the intel had only two antennas, and the atheros needs
three. I works, but pretty bad. 
I've quickly read on the driver sources that there is a sort of antenna
management, is it possible to hack it to forbid the usage of one
antenna, or is it in card internals ?

Jean.

You only need two antennas with these cards, at the moment.

Well, if the antennas roles switch for reception or emission, and i have
only one antenna well connected (and the other on the not-needed third
antenna), i guess i'll have both emission add reception problems, can
you explain me quickly how it works ?

Jean.
