So, I had my favorite network admin turn on SSID broadcast on the AP as
a temporary measure. That way I could debug my ipw2200 connection with
one less worry.
Things started to work !
madwify is indeed buggy in my configuration.
Once SSID broadcast was turned off, I could use ap_scan=2 and a full set
of specifi directives, and it continued to work.
Nevertheless, if there is no activity on the card, I loase
authentication and the supplicant has a hard time re-authenticating and
goes into loops. If I quickly get an IP address, it looks stable..
Finally, my company is using multiple SSIDs throughout the building. Do
I just duplicate the network blocks of the conf file with just different
SSID names, all at the same priority ?
Thanks for the help.
