In my FSO M5-equiped FR eth0 visible by iwconfig and my WiFi points
successfully scaned by iwlist.

But, seems like I found another unpleasant bug :(

I tryed setting up direct WiFi network access (without hardware Access
Points) for FR by hands (I successfully used such scenario for
configuring wireless-networking for some OLPCs & traditional notebooks):

# iwconfig eth0 mode ad-hoc
# iwconfig eth0 essid "my-wifi"
# iwconfig eth0                
eth0      AR6000 802.11g  ESSID:"my-wifi"  
          Mode:Ad-Hoc  Frequency:2.457 GHz  Cell: 4E:72:EC:8E:38:88   
          Bit Rate=1 Mb/s   Tx-Power=15 dBm   Sensitivity=0/3  
          Retry:on   
          Encryption key:off
          Power Management:off
          Link Quality:0/94  Signal level:-95 dBm  Noise level:-96 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

# iwconfig eth0 channel 1
# iwconfig eth0 key restricted 1234567890 
# iwconfig eth0
eth0      AR6000 802.11g  ESSID:""  
          Mode:Ad-Hoc  Frequency:2.457 GHz  Cell: 4E:72:EC:8E:38:88   
          Bit Rate=1 Mb/s   Tx-Power=15 dBm   Sensitivity=0/3  
          Retry:on   
          Encryption key:1234-5678-90   Security mode:restricted
          Power Management:off
          Link Quality:0/94  Signal level:-95 dBm  Noise level:-97 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

I lost my ESSID at this step and try setting up this one once again:

# iwconfig eth0 essid "my-wifi"

After that system hangs up and blinking by red LED in AUX button.

Seems like "restricted" key is key point for this situation -- with open
key all works good.

Can someone try to reproduce this situation? May be something wrong with
my hardware...
