I have the same problem with madwifi-ng.  It associated, does the dhcp 
thing and after a few seconds tears it all down and starts again.

I found that if I only have one network clause and set ap_scan=2 and 
ssid_scan=1 then I can get it to work.

This is with WEP.  I can't get WPA-PSK to work at all.  Lots of 
"operation not supported" messages.
