Hello!
I'm trying to connect to an AP. I know the essid and the key both in hex and in ascii. So I write, as usual

Code:
# iwconfig wlan0 mode managed essid someessid key somehexkey

# dhclient wlan0

No DHCPOFFERS received.
No working leases in persistent database - sleeping.


Please tell my of any reasons why it's not possible for me to connect to this AP. I can connect to other WEP- and WPA-encrypted networks so I think it must be something "wrong" with this particular network.

Any suggestions?
