I have seen the later mail and starting now to see your problem.
It seems that you can get associated if you are not giving the
essidi (off), but you have trouble with the initial setup. I have
not a lot of experience with Debians init scripts and WLAN
installation, but there have been reports that they doesn't work
well with WLAN adapters. I know this a poor situation, but
currently we cannot do a lot about it.

For the softmac driver I'm always recommending to set all the
necessary parameters before you call ifconfig eth0 up and I
believe this is the problem with the default debian configuration.
ifconfig eth0 up means in the WLAN code that the device should
start to associate and this requires the parameters to be set

Kind regards,
