The mac mini atheros works 100% out of the box.
Bad news bcm43xx type cards or the bcm4311 (dell 1390) I have works but gets to max 50% power.
I tried to load the bcm43xx module only after unloading the mac80211 , bcm43xx_macsoft , rc80211 etc modules but could not find it.
This is not a major problem for me or for anyone as it just needs a bit of fine tunning to get it fixed.
This might also be totally different on other bcm43xx cards as mine is know to be DELL experience and others might work 100%.
I have a clue that the laptop powersaving tries to force powersaving on the wifi card and so the signal goes less but the actual download speed is still 95% of what it should be. Might limit distance in actuality.
Sucking my thumb here to figure it out. LOL
