Cannot get my WiFi to work


My WiFi does not work although the kernel seems to support it. I will list the output of a few commands.

Code:
lspci|grep -i network
07:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)
Code:
[root@localhost dispatcher.d]# iwlist scanning

virbr0    Interface doesn't support scanning.
The first router listed here (Cell 01) is my WiFi router. So it seems that I can even scan the routers properly. Please give me commands so that I can get the WiFi up and running.

P.S. I am using Fedora 13 and the configuration through the graphical interface does not work. The GUI also does not work for normal LAN connections, so I never had faith in it anyway.

It seems to be a very difficult task now as I am having lots of stuff installed and configured. By I did try the Fedora 16 live distro and it gives the same result.

It seems that I have an inet6 address properly configured through dhclient
Code:
[root@localhost wifi-radar-2.0.s08]# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:23:4D:79:A6:31  
          inet6 addr: fe80::223:4dff:fe79:a631/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:66 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 b)  TX bytes:13216 (12.9 KiB)
I think my problem is with WPA version 1 security. Can you please explain how to configure that? I only know my password.

Cool

Solved it.

first
Code:
wpa_passphrase linksys "myPassword"
network={
	ssid="linksys"
	#psk="myPassword"
	psk=d26b46ba343c694ae05f210d715e2618d24c3d231dd5e184aa9a0c4fb72fb71c
}
then

Code:
vi /etc/wpa_supplicant/wpa_supplicant.conf
and the edit the file to look like this

Code:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
scan_ssid=1
ssid="linksys"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk=d26b46ba343c694ae05f210d715e2618d24c3d231dd5e184aa9a0c4fb72fb71c
}
and then at the end

Code:
[root@localhost wifi-radar-2.0.s08]# wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf 
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
ioctl[SIOCSIWSCAN]: Device or resource busy
Failed to initiate AP scan.
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
Trying to associate with 68:7f:74:f8:22:45 (SSID='linksys' freq=2412 MHz)
Associated with 68:7f:74:f8:22:45
WPA: Key negotiation completed with 68:7f:74:f8:22:45 [PTK=TKIP GTK=TKIP]
CTRL-EVENT-CONNECTED - Connection to 68:7f:74:f8:22:45 completed (auth) [id=0 id_str=]
now configure the interface with dhcp
Code:
[root@localhost Documents]$dhclient wlan0

And its working real smooth
