Wireless connection problem ( WPA or something else)

Hello, I'm trying to connect to my AP, using:
Atheros Communication AR50056
I think my OS recognized it correctly, but I have problems with connection. First some more info, that may help you to help me
ath0      Link encap:Ethernet  HWaddr 00:16:E3:83:0D:04 
          inet6 addr: fe80::216:e3ff:fe83:d04/64 Scope:Link

          Interrupt:177 Base address:0x8000

lo        Link encap:Local Loopback 
          inet addr:  Mask:

          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          collisions:0 txqueuelen:0
          RX bytes:11604 (11.3 KiB)  TX bytes:11604 (11.3 KiB)

wifi0     Link encap:UNSPEC  HWaddr 00-16-E3-83-0D-04-00-00-00-00-00-00-00-00-00-00

          Interrupt:193 Memory:dca00000-dca10000
And now iwconfig:
lo        no wireless extensions.

wifi0     no wireless extensions.

ath0      IEEE 802.11g  ESSID:"siec"  Nickname:"siec"

          Retry:off   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=42/94  Signal level=-53 dBm  Noise level=-95 dBm

          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

eth0      no wireless extensions.

sit0      no wireless extensions.
It seams to look OK?
What I have done to connect? First I installed two applications, that should help me: network-manager and wifi-radar. When I try to run first one, it doesn't recognize any AP. I've got only error message:
sudo NetworkManager --no-daemon
NetworkManager: <information>   starting...
NetworkManager: <information>   eth0: Device is fully-supported using driver '8139too'.
NetworkManager: <information>   nm_device_init(): waiting for device's worker thread to start
NetworkManager: <information>   nm_device_init(): device's worker thread started, continuing.
NetworkManager: <information>   Now managing wired Ethernet (802.3) device 'eth0'.
NetworkManager: <information>   Deactivating device eth0.
NetworkManager: <information>   Updating allowed wireless network lists.
NetworkManager: <WARNING>        nm_dbus_get_networks_cb (): error received: org.freedesktop.NetworkManagerInfo.NoNetworks - There are no wireless networks stored..
And nm-ap photo:

Something is wrong ... when I run
iwlist ath0 scan
it show my two available APs.

Next I tried wifi-radar. It show my two available APs: example photo ), but I can't connect. They use WPA, but I can't configure it

Why network-manager don't show my APs? It's problem with my card or with WPA configuration? How can I configure WPA ( with GUI)? Please help me

You need to list the distribution you are using, and the wireless card you are using as well. (Incidentally, cards using the Atheros chipset need to have proprietary drivers installed or use a wrapper like NdisWrapper. Some distributions do not include them for legal or idealogical reasons.) Further, setting up WPA is problematic in most Linux distributions since you need to use the wpa_supplicant package to enable it and configuring it is not easy. (PS: I know this post is not much help, but unless you list specifics, it is not likely you will get many replies.)
