Yan,<br><br>I've had a similar issue and I had to reset the card to get it to work properly. You can do that with "iwpriv wlan0 reset 1". Try that. I hope it helps.<br><br>Timur<br><br>On 8/3/07, <b class="gmail_sendername">

<div><font size="2">I met a strange problem in using hostap driver 0.4.9 for
Prism cards. After I inserted the card, the driver could recognize the card
and showed the general information after I ran "iwconfig wlan0". However, after
I ran "iwconfig wlan0 mode Managed", the essid became empty(""). After that,
whatever essid I assigned by running "iwconfig wlan0 essid essidname", the essid
was always empty. When I ran "iwlist wlan0 scan", I got the error message
"wlan0 Interface doesn't support scanning : Network is
down". </font></div>

The detailed output is attached.</font></div>
