Hi Johannes, so I am running the latest wireless-testing.git tree based on 2.6.30-rc6 and when connecting to my A-band only configured AP, I don't get any packets through. Even DHCP fails. The only thing I see in dmesg is [ 3221.246392] wlan0: dropped frame to 00:1f:f3:xx:xx:xx (unauthorized port) The wireless-testing.git tree based on 2.6.30-rc5 was working fine with that access point. I was actually happily using the A-band since it is less busy here. Any ideas why this might broke?
