client mode using 64bit WEP-key

client mode using 64bit WEP-key Hi!
I need help to connect my wl500 in client mode using 64bit WEP-key to an AP.
I´m using the 1.7.5.9-2 firmware and made the next changes
# turn on sta mode (0 = ap, 1 = sta, 2 = wet)
nvram set 13_x_ClientMode=1
# commit settings
nvram commit
# reboot
reboot

From the owner of AP i got the next data:
ESSID darkmoon
Channel Number 5
WEP 64bits - phrase - "light"
IP:192.168.2.10-20
gate: 192.168.2.1

~ # wl scanresults
SSID: "darkmoon"
Mode: Managed RSSI: -61 dBm noise: -93 dBm Channel: 5
BSSID: 00:50:FC:G6:41:20 Capability: ESS WEP
Supported Rates: [ 1(b) 2(b) 5.5(b) 11(b) ]

~# wl join darkmoon key light

~ # wl status
SSID: "default"
Mode: Managed RSSI: -64 dBm noise: -92 dBm Channel: 6
BSSID: 00:80:C8:38:44:AD Capability: ESS
Supported Rates: [ 1(b) 2(b) 5.5 11 ]

or sometimes

~# wl status
eth2: Invalid argument
Not associated. Last associated with SSID: "default"

What do I wrong?

you should set it up through the webconfig

enter the details as you would do as if it was your AP

Thanks, after setting up in webconfig it shows that i'm associated with the AP, but i can't ping to the AP or other IP-s.
