I am having a Linksys router with WEP encryption enabled.
When I try to connect to it using wpa_supplicant using following
options, I establish a successful connection.

wpa_supplicant -iath0 -cwpa_supplicant.conf -B

and I get following output,

root(a)hmp10:~# channel hint set to 2462
Connect called with authmode 1 dot11 auth 1 PW crypto 2 PW crypto Len

After this when I run iwconfig, I get following output,
lo no wireless extensions.

It shows that it is connected to wifi router. Now when I try to obtain
IP with udhcpc -iath0 -n, I do not get the IP address. I end up with
following messages.
udhcpc (v1.9.2) started
Sending discover...
Sending discover...
Sending discover...
No lease, failing


Also my wpa_supplicant.conf has following entries.

ctrl_interface=/var/run/wpa_supplicant GROUP=wheel
network={
ssid="a123"
key_mgmt=NONE
wep_key0=365a639ce0
wep_tx_keyidx=0
}

I am trying this when my wired connection is also UP and running.
