Unfortunately, I still seem to have problems with the ath9k driver. While pinging my wireless router - which is just next to where I'm sitting - I consistently have 2 packets dropped after every 3 packets.

And I'm running this entire exercise sitting right next to the router - which is a Linksys WRT54GL running OpenWRT Kamikaze (8.09) release. The rest of the setup on the laptop is plain standard Kubuntu setup - no modifications done to any other file. I'm including both ath9k-devel and linux-wireless mailing lists in Cc: - maybe, someone from there might have a clue about what's going on.
