Connect to Wi-Fi Network through Ubuntu Terminal

Lot many people end up in a situation where they want to use internet while in console mode. It’s not that difficult task to connect to the Wi-Fi from the terminal.
There are some simple steps that you need to follow.

  1. Open the terminal.
  2. Type ifconfig wlan0 and press Enter. You will not see any output in the terminal, as this command just turns your wireless card on. Most wireless cards are designated wlan0. If yours has a different designation, use that instead.
  3. Type iwconfig wlan0 essid name key password and press Enter. Replace name with the actual network name, and replace password with the actual security key for the network. If your wireless network does not require a security key, do not enter key password.
    Note: If you want to type the ASCII password, you would use iwconfig wlan0 essid name key s:password.
  4. Type dhclient wlan0 and press Enter to obtain an IP address and connect to the WiFi network.

  1. here’s my output,
    something is worng,
    what to do?

  2. My wireless card name isn’t wlan0 and when I put iwconfig into the command line the only thing which shows up is:
    lo no wireless connections
    How do I find and turn on and find my wireless card. I checked rfkill list, and nothing is blocked, but the only thing that shows up is:
    0: hci0: Bluetooth

  3. `iwconfig wlan0 essid NetworkName key s:asciipassword` says “Error for wireless request “Set Encode” (8B2A) : SET failed on device wlan0 ; Invalid argument.”
