Need to know how to configure a Wi-Fi connection from CLI: iwconfig is not enough

Kenny_Strawn · 10-04-2010, 12:08 AM

Is there a command I need to type from the pure CLI other than:

Code:

iwconfig wlan0 essid <SSID> key <network key>

to configure a WEP-enabled Internet connection from a pure CLI (no X running)? If so, please post it here.

I suggest that you look at 'How to Ask Questions the Smart Way' so in the future your queries provide information that will aid us in diagnosis of the problem or query. We will aid you when you help yourself to a solution. Provide us with what you have attempted and then maybe someone will be able to assist.

Assuming that your device is 'wlan0' then you should either use 'dhcp' or a static IP assignment. Your command shown assumes that the assignment has been made for an IP address.

As root you can use the below to configure a static IP for your wlan0 on your LAN;

Code:

 ~#ifconfig wlan0 192.168.1.18    #<<< available IP
 ~#route add default gw 192.168.1.1 #<<your gateway
 ~#iwlist wlan0 scan #<< use information to fill in for essid & ap information
 ~#iwconfig wlan0 essid "Your Wireless"
 ~#iwconfig wlan0 key your_key_here
 ~#iwconfig wlan0 ap xx:xx:xx:xx:xx:xx #<<Your _ap_from iwlist

I use the script below to setup my wireless while experimenting.

Code:

  wlan.sh;
  #!/bin/bash
 #
 #10-26-09 13:30 
 #setup the wlan0 device
 #
 /sbin/ifconfig wlan0 192.168.1.18
 /sbin/route add default gw 192.168.1.1
 /sbin/iwconfig wlan0 essid "Your_Wireless_Access"
 /sbin/iwconfig wlan0 key Your_key
 /sbin/iwconfig wlan0 ap 00:00:00:00:00:00 << your AP HW address from above iwlist scan

You might take a look at wicd as well. It now has a console version, wicd-curses that works very nicely.
