Now that was perfect - There are so many who are good with linux but cannot communicate - Thankfully, it's not you. Please write a linux basics book. It will sell. Very well.

How to connect to a wireless network from the Ubuntu command line using a WPA/WPA2 Personal key.
For this to work.. you need to have WPA-Supplicant installed ... Ubuntu comes with WPA-Supplicant installed by default.
if not present, install it using this command: sudo apt-get install wpasupplicant
Ubuntu doesn't use a root password by default ...so we need to use the sudo command here.

Now we need to create 2 files: wireless-wpa.sh + wireless-wpa.conf using the vi command. For those who are not familiar with vi , I will guide you through this.

OK ..lets start: first we gonna create the wireless-wpa.sh
type: sudo vi wireless-wpa.sh
press the "i" button ones and insert text below.
#!/bin/sh
iface=eth1

#shut down interface
ifconfig $iface down

#set ad-hoc/management of wireless device
iwconfig $iface mode Managed

#enable interface
ifconfig $iface up

#stop any persistent wireless wpa2 sessions
killall wpa_supplicant

#apply WPA/WPA2 personal settings to device
wpa_supplicant -B -Dwext -i $iface -c ./wireless-wpa.conf -dd

#obtain an IP address
dhclient $iface

Now we need to save this file and quit vi.... press "esc" button ones ... then type.. :wq ( you need to type the : also )
Thats done ... now we gonna make the wireless-wpa.conf

type: sudo vi wireless-wpa.conf
press the "i" button ones and insert text below.

# config file using WPA/WPA2-PSK Personal key.

ctrl_interface=/var/run/wpa_supplicant

network={
ssid="my_router_id"
scan_ssid=1
key_mgmt=WPA-PSK
psk="1234567890"
}

Now we need to save this file and quit vi.... press "esc" button ones ... then type.. :wq ( you need to type the : also )
That's also done ... now we need to set the permissions for these 2 files.

sudo chmod 755 wireless-wpa.sh
sudo chmod 644 wireless-wpa.conf

Make sure you put these 2 files in the same directory anywhere you like...else it will not work.
Run the following command to make a connection to your wireless Router/Accespoint/
sudo ./wireless-wpa.sh

That's all .... have fun!

Hi Matt ... do you still need some tips for handling WPA-PSK connections ?

Very good article mate !

For those who can't get it to work ... remember to set your wireless card to the correct channel on wich the accespoint is running at.

iwconfig wlan0 channel 6 (example)

Hi there,

I was very interested to test out your tutorial on my home laptop that connects to my wireless router. My router requires that you enter in a long numerical wep key. I typed in the following:

sudo iwlist wlan0 scan (it found the ESSID for my wireless router. That was nice)
sudo iwconfig wlan0 essid "myssid" key 12345678912345678912345 (obviously not my key. When I typed this in it gave me no complaints)
sudo dhclient wlan0

The dhclient command started looking for DHCPs using the netmask 255.255.255.255 and port 67. I thought this was weird so I tried to tell dhclient to look for a dhcp using my normal netmask 255.255.255.0. I typed in 'sudo dhclient -s 255.255.255.0'. It still wouldn't work!

I also tried setting up iwconfig to translate my numeric key into hex by typing in 'sudo iwconfig wlan0 key s:12345678912345678912345' after telling it my SSID. That still didn't work.

Oh well, maybe some day i'll get wireless working from the command line without too much hassle!

how do i connect to a point if it dosnt have an essid i can connect to it in windows but ubuntu wont connect without a essid but it still picksit up in a servey

Re: How to connect to a wireless network from the Ubuntu command line

Matt Wilson — Tue, 20 Jan 2009 09:36:21 -0000

Hi Andreas, use sudo iwlist eth1 scan to find out if your wireless
card can see the network. Then use sudo iwconfig eth1 to see what
your card's essid and key settings are, then set them.

Some bad news -- I haven't been able to connect to a
WPA2-authenticated wireless network yet.

Good luck!

aargh, Ive got the same problem.. Installed Ubuntu Server edition 8.10 using no gui, and cant connect to the wireless network. I have tried the things explained over, and get the same results..

If you find it out, please tell :)

Hi -- I think that you'll get better feedback if you post your problem
to some mailing lists.

Also, after you run ifconfig wlan0 up, run iwconfig wlan0 to see what
ESSID you are pointing at.

Good luck!
