Michael,
is this for all 4318? I'm doing extensive testing these days with both 4318 and 4306 on x86. I always get very good performance with latest hostapd on 2.6.29-rc2-wl. I can also reach maximum theoretical throughput if I choose channel 14 to limit interferences. I get max throughput independently of the board running hostapd and traffic direction. All this applies to both AP and stations being x86 linux based, e.g., if I try to join an x86 AP running b43 from my macbook I can get good performance only occasionally. Good performance also if the station is a linksys wrt54gl (it uses a 4318). I can't instead run hostapd successfully on these linksys.
