This line generally appears when the card comes on-line; if all goes well, it should soon be followed by something like 'ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready' >From my dmesg (with the b43 driver, which also uses mac80211, like ath9k): ADDRCONF(NETDEV_UP): eth0: link is not ready eth0: direct probe to AP 00:17:5a:4f:31:c0 try 1 eth0 direct probe responded eth0: authenticate with AP 00:17:5a:4f:31:c0 eth0: authenticated eth0: associate with AP 00:17:5a:4f:31:c0 eth0: RX AssocResp from 00:17:5a:4f:31:c0 (capab=0x401 status=0 aid=53) eth0: associated ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready > The only way I found to make the thing work again is to > > modprobe -r ath9k && modprobe ath9k > > (that is, unload and relaod the driver).

I'm not much of an expert, but here are a couple of suggestions: Try disabling WEP, and see if the problem persists. Try configuring the interface manually, without DHCP: ifconfig wlan0 up iwconfig wlan0 essid xxxxxxxx ifconfig wlan0 x.x.x.x Read the dmesg and syslog carefully, and perhaps post them here.
