configuring wireless on command line interface

  • 772

Sometimes I boot into recovery kernel with CLI and networking for troubleshooting my laptop. So is there a way to connect to a wireless router or AP over command line? If it is possible what are the commands for the following:

  1. To list available networks.
  2. To connect to a network with: SSID, WPA2 key and DHCP mode.
  3. A command to connect with: SSID, ad-hoc mode, ip-address, netmask, gateway.

    You will need the wpasupplicant package in order to connect to a network secured with wpa or wpa2.

    Listed by order :
    1 : sudo iwlist scan

    2 : sudo iwconfig <interface> essid "my network"
    iwpriv <interface> set AuthMode=<WPA2PSK or WPA2AES>
    iwpriv <interface> set <WPA2PSK or WPA2AES>='WPA PASSPHRASE'

    3 : sudo iwconfig <interface> essid "my network"
    ifconfig <interface> inet <ip> netmask <mask> then set a route to your gateway route add <destination> gw <gateway ip>

  2. nm-tool or sudo iwlist scan will show you all available wireless networks.

    There's a cnetworkmanager package that ought to let you control Network Manager from the command line. I've never used it myself.

  3. I think iwlist and iwconfig does this. Here is the forum that talks about this.
