I had some issues originally but here is my final working setup:

1) remove networkmanager:
  #opkg remove networkmanager network-manager-applet

2) edit /etc/network/interfaces to include something like this depending on your network needs
 auto wlan0
        iface wlan0 inet static
        pre-up /sbin/iwconfig $IFACE key 9f92b5cabe
        pre-up /sbin/iwconfig $IFACE key open
        pre-up /sbin/iwconfig $IFACE essid tPartyExtravaganza

3) At this point, to get a connection I had to log in over the serial console and run
 #ifdown wlan0
 #ifup wlan0

4) To do this automatically on boot I wrote the following init script, as S90mywifi in /etc/rcS.d (make this executable)

  # Startup script for robot

  case "$1" in
          echo "Wifi fix?..."
          ifdown wlan0
          ifup wlan0
          echo "done."
          ifdown wlan0
          ifdown wlan0
          ifup wlan0
          echo "Usage: ntpd { start | stop | restart | reload }" >&2
          exit 1

Now I have working wifi on my Overo Fire on the Angstrom distrob that came with it.

Good luck,

I'm having the same problem here.  An "iwlist wlan0 scan" shows me my access
point and many others.  I take this to mean that at least part of the
software and hardware (the receive section) is functional.  Every
combination of ifup, ifdown, iwconfig, ifconfig fails to get me past the
same output as quoted below (no connection).  I'm running the 2.6.34 kernel.

Anyone have a solution yet?  Thanks for any help.
