	Hello,

  I have a X31 Thinkpad with an AR5413-based wireless mini-pci card. My
system is Debian Etch with latest Debian's madwifi sources, and I
noticed exactly the same behaviour : I tought at first there was a
problem with DHCP client, but debugging a bit shown me the problem is
during association with access point (I use a WPA encryption, and using
wpa_supplicant with debug, I see authentification timeout... from times
to times ; sometimes, shutting down/up again don't help, and I observed
recently that killing wpa_supplicant before restarting interface could
help (but I'm not sure it's 100% working ...)...

  If you find a solution, I'd be happy to know it !

	With regards,
		Fred.
