Hello!
A while ago I bought a D-Link DWA-556 a/b/g/n PCI-E card, and have tried
to get it fully working since. It works with >2.6.27, but is really really
slow. At the most I get 7-800KBps, even with a link quality at aprox
60-70/100. If I place my laptop with iwlwifi ontop of my other machine, I
get the same link quality, but at least 10 times the speed.
I can see on your supported chipset page that AR5416-AR2133 is supported,
but not AR5418-AR2133 - as my dmesg reports my cards as.
My DWA-556 card got 3 antennas by the way..
My accesspoint (D-Link DIR-855) is set to 802.11n network only, with wpa2
and aes only, and 20MHz (if I select auto 20/40, my ath9k driver cannot
connect).
I'm currently running latest wireless-testing kernel.
Thanks in advance!
