First issue the command iwconfig from a shell to see the assigned name of your wireless card .
in this example we will be working with the ath0 .
make sure you have the WPA_supplicant package installed ,visit www.linuxappfinder.com ,usually it is installed by default in ubuntu.
create a new file called wpa_supplicant.conf ,using nano or your favourite editor and type the following code:
ssid=”your ssid name”
psk=” type in your passphrase here the one you use to connect to the AP ”
now save the file somwhere ,mainly /etc/ .or any place you want .
now you need to inform wpa_supplicant to use this file to connect to the wireless AP with the above information .
type in the shell :
wpa_supplicant -D wext -i ath0 -c /etc/wpa_supplicant.conf
the connection process will begin ,you should see at the bottom line something like :
CTRL-EVENT CONNECTED – connection to XX:XX:XX:XX:XX completed .
NOTE : DO NOT CLOSE THIS SHELL .(open up a new shell window complete the down steps ,static or dynamic and then you may close this shell ,some drivers requires this shell window to stay open.)
now i will explain the code above :
wpa_supplicant is the command to run the WPA tool
-D wext , this will tell linux to use the generic wireless wext driver ,it works fine with my WG511T netgear
-i ath0 ,this is the wireless interface
-c wpa_supplicant.conf ,this is to tell wpa_supplicant the location of the conf file ,i kept it in /etc/ so you may change the location to wherever you saved it.
Static ip address
Now it is time to give the atho interface an ip ,netmask ,gw ,dns and so on .
open up a new terminal window
and type the following :
ifconfig ath0 192.168.1.20 netmask 255.255.255.0
route add default gw 192.168.1.254
echo nameserver 192.168.1.254 > /etc/resolv.conf
this is if you want a static ip.
the ip’s used above is an example ,use your own ip’s ,netmask ,gw and dns .
DHCP ip address:
if you want to you the DHCP in your Wireless AP or anyother DHCP you already setup then skip the above steps and
just type :
both ways static or Dynamic thru DHCP should connect you to your wireless network.
you should be connected by now .
NOTE : this is to connec to WPA based security ONLY ,in order to wep ,it has a different code ,i might be posting it soon .
