Re: networking question : wpa_supplicant, ifplugd and interfaces -- solved

Hi,
Thanks to all your replies. Here is what the problem turned out to be
and how I solved. 

The problem was that the kernel hotplug dispatcher loads ipw3945 
too early and without invoking modprobe. To fix it a file -
/etc/hotplug/blacklist.d/ipw3945 needs to be created with the sole
content being a single line containing ipw3945. Also it is better to
start wpa_supplicant very late in the boot process after ifplugd (this
is contrary to the suggestion in the wpa_supplicant documentation ).

Thanks again.
B Thomas
