How to set up wireless from the command line (this assums wlan0 is your wireless card):

  • log in as root
 su
  • Enable the wireless card
 ifconfig wlan0 up
  • Back up your wpa_supplicant config file
 cp /etc/wpa_supplicant.conf /etc/wpa_supplicant.conf.back
  • Edit your wpa_supplicatnt.conf to remove all but one 'network' block (or leave a couple if you're going to connect to more than one network)
 vi /etc/wpa_supplicant.conf
  • Edit that 'network' block with the appropriate information for your router then save and exit the file
  • Connect to your wireless network
 iwconfig wlan0 essid <ssid>
  • Authenticate yourself on the network
 wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B
  • Check your wireless card
 iwconfig wlan0
  • verify that the SSID is <Your Router>
  • wait 10 seconds
  • Request an IP address from your router
 dhcpcd wlan0
  • Check to see that you have a valid IP address for wlan0
 ifconfig
  • Log off root
 exit

Note: Although this should work, it may require hours of frustration with little explanation of why things are not working. I recently talked my friend through this over the phone and it took about 3 hours all together, and that was after I had already spent a couple of hours setting it up on a different network to make sure it was working.
