I don't have time to investigate this right > now, but I'll try to find some time during the evening. I have looked at this now a bit and I don't think this is an iwl3945 problem. Scanning seems to stall in some situations and iwl3945 doesn't even receive the scan command. Here's an example what's happening with wpa_supplicant from debian unstable: $ sudo ifup wlan0 [ 104.468073] iwl3945 0000:03:00.0: firmware: requesting iwlwifi-3945-2.ucode [ 104.533234] iwl3945 0000:03:00.0: loaded firmware version 15.32.2.9 [ 104.612049] phy0: device now idle [ 104.613091] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 106.968392] phy0: device no longer idle - scanning [ 109.561397] phy0: device now idle [ 109.563737] wlan0: deauthenticating by local choice (reason=3) [ 109.563743] phy0: device no longer idle - in use [waited a while] $ sudo iwlist wlan0 scan wlan0 Interface doesn't support scanning : Device or resource busy $ sudo iwlist wlan0 scan wlan0 Interface doesn't support scanning : Device or resource busy $ sudo wpa_action wlan0 stop [ 191.649653] wlan0: deauthenticating by local choice (reason=3) [ 191.697619] phy0: device now idle Also I have been able to reproduce the problem once with iw. For some strange reason I have had to reboot my laptop to reproduce this, unloading all wireless related modules (expect rfkill which I can't unload due to dependencies) is not enough. -- Kalle Valo
