USB WLAN recommendation?

Anyhow dhcp client never gets an offer

# dhclient wlan0
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 3
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 14
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 16
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

while getting this:

ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Invalid argument
ioctl[SIOCS80211, op=20, val=0, arg_len=7]: Invalid argument

I moved the SSID to a different channel that's less occupied and moved the machine right next to AP. No difference.

Try to setup IP by hand with these:

# ifconfig wlan0 inet 10.0.0.123/24 up
# route set default 10.0.0.1

... assuming you are on the 10.0.0.0/24 network with 10.0.0.1 as gateway.
