Thanks, You are having the exact Philips adapter I was referring to earlier : PCI-ID [168c:0012] sub [17ab:8310]. This one only works perfect with the madwifi "ath_pci" driver module, not provided from Ubuntu any more. And from all the logs above, doesn't seem to work with the ath5k kernel driver module, the only module provided in 9.10/Karmic. From your lspci output it seems you are running the well performing madwifi module (Kernel driver in use: ath_pci), self-compiled or back on 9.04/Jaunty ?

Thanks, You are having an atheros based adapter used in some T40 and R50 series : PCI-ID [168c:1014] sub [1014:057e], which seems to perform well with the ath5k kernel driver modules - in my experience the default drivers from the linux-image package works quiet well with the [1014:057e] adapter, but it could be that the backports-modules works even better - I will try the backports next time I install T40/R50 series.
