I'm using an ordinary Desktop-PC with Kubuntu and an selfbuilded 
Kernel-2.6.26.2 / Kernel-2.6.26.rc3. with both Kernels I tried the Ath9k 
using a D-Link DWA-547 (AR5416 inside). I simply have the same lossrate 
of up to over 50% while connecting to a 11g network.
So unfortunately it doesn't seam to be just a problem of AR5418.
