dari cli misal:
=============
root@mywisdom-Vostro1310:/home/mywisdom# service network-manager stop
root@mywisdom-Vostro1310:/home/mywisdom# ip link set eth1 down
root@mywisdom-Vostro1310:/home/mywisdom# iwconfig eth1 mode ad-hoc
===============

selanjutnya kita set nama essid kita:
=======================
root@mywisdom-Vostro1310:/home/mywisdom# ifconfig eth1 up
misal kita kasih ip addr akses poin 192.168.1.1
========================
root@mywisdom-Vostro1310:/home/mywisdom# ip addr add 192.168.1.1/24 dev eth1
ok mari kita liat:
root@mywisdom-Vostro1310:/home/mywisdom# ifconfig -a

ok selanjutnya kita set password dengan menggunakan wpa:
misal kita kasih password: mywisdom123 buat password dengan wpa_passphrase
===========
root@mywisdom-Vostro1310:/home/mywisdom# wpa_passphrase mywisdom 1234567890
network={
ssid=”mywisdom”
#psk=”1234567890″
psk=c2d332723db9d5b52c9e269cd55cf029217ab9f14616dcbafcc76c6d55cbfab4
}
=================
===============
root@mywisdom-Vostro1310:/home/mywisdom# cat adhoc.conf
ap_scan=2
network={
ssid=”mywisdom”
mode=1
frequency=2412
proto=WPA
key_mgmt=WPA-NONE
pairwise=NONE
group=TKIP
#psk=”1234567890″
psk=c2d332723db9d5b52c9e269cd55cf029217ab9f14616dcbafcc76c6d55cbfab4
}
============
lalu jalankan dengan wpa supplicant:
=============================
root@mywisdom-Vostro1310:/home/mywisdom# wpa_supplicant -c adhoc.conf -ieth1 -Dwext
