Software confusion aside, now you have my interest.
You have tried using a known good antenna(s), and a known good card, and
still saw the problem ?
My first suggestion in a case like this is to replace the main antenna
with a known good one and retest.
The main antenna is the left-most one when looking at the motherboard,
and is usually connected to the right-most connector on the WLAN card
The next suggestion is to replace the WLAN card. If you've done both of
those and it still doesn't work well, look in /var/log/messages for any error
messages from the driver (indicating a possible problem with the SDIO bus).
Just about the only thing left to try is to measure the +1.8V and +3.3V at
the card socket while Linux is running, there could be something wrong with
the power switches Q29, Q37 and Q38.
