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!
