Wireless nao Funciona

[Mauro Storch <maurostorch@gmail.com>]

Ola pessoal.

Tenho um problema aki,
Possuo um AP D-Link DI-524 / 802.11 G
e no meu note um AirLink+ AWLL3025, Chipset ZyDAS 1211

vejam o que eu tenho:

# iwlist wlan0 scan
wlan0     Scan completed :
          Cell 01 - Address: 00:0F:3D:40:83:28

                    Bit Rate:48 Mb/s
                    Bit Rate:54 Mb/s

ai dou o comando:
# iwconfig wlan0 essid rcinfom

# iwconfig wlan0
wlan0     802.11b/g NIC  ESSID:"rcinfom"
          Mode:Managed  Frequency=2.462 GHz  Access Point: 00:00:00:00:00:00

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Acontece que ele acha o AP, mas nao conecta, fica 00:00:00...
e tb nao pinga a rede, ja testei em outros APs 802.11G e consegui
setar o rate pra 11M e funcionou blz, em APs 802.11b tb funciona blz.
Mas nesse D-Link nao funciona, alguem tem alguma explicação?

Falow!
