<DIV><FONT face=宋体 size=2>Hi, Timur,</FONT></DIV>
<DIV><FONT face=宋体 size=2></FONT> </DIV>
<DIV><FONT face=宋体 size=2>Actually I forgot to activate the interface. In my
tests before, I ran "dhclient wlan0", so the interface was turned on by
"dhclient". This time I do not want to use dhcp, but I forgot to run
"ifconfig wlan0 up". So I met those strange problems. After I ran "ifconfig
wlan0 up" told by Kelly, the problem was gone.</FONT></DIV>

<DIV><BR></DIV>This will reset the firmware, so all settings of power, etc
will have to be reset. Also note that with 0.4.9 this command will hang
the card and cause a kernel panic on 2.6.11 and above if issued too many times
in succession. Usually not an issue, But a few thousand resets and it
will do it.

<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
"wlan0Â Â Â Â Interface doesn't support scanning :
Network is down". </FONT></DIV>

<DIV><FONT size=2>The version of linux kernel is 2.6.11. I tried both
