Hi,
I am trying WPA in Adhoc Mode.
My set-up is,
Senao 400mw radio
Madwifi 0.9.2
Wpa_supplicant v0.5.7
Debian 2.6.18
Here is my wpa_supplicant.conf file,
------------------------------------------------------------------------
--------------------------
ctrl_interface=/var/run/wpa_supplicant
ap_scan=2
fast_reauth=1
network={
ssid="adhoc_wpa"
#psk="saurav123"
mode=1
proto=WPA
key_mgmt=WPA-NONE
pairwise=NONE
group=TKIP
psk=d7cb9bba6d1f2c077d51c27fb332a572833de29fc3158144e7a63fada40445f4
}
------------------------------------------------------------------------
-------------------------------
Please note that I browsed through the mailing list archives and also in
google to find the WPA solution in Adhoc Mode.
Some of the users are claiming to be successful with the setup but some
of the others are not.
So I could not find a conclusion about the problem.
I cross checked several times the wpa_supplicant.conf file and tried
different options like TKIP/CCMP, using PSK in Hex/String etc. but
without success.
