Iwlist wlan0 Scanning

3. Assuming that you want to connect to a network myhome (that is, Essid is a myhome network), then enter the command

Iwconfig wlan0 Essid "MyHome"

If the network is encrypted and the password is 0123456789, enter the command

Iwconfig wlan0 Essid "MyHome" key 0123-4567-89

4 If normal, enter

Iwconfig Wlan0

You can see the parameters that are properly connected.

5. Start the wireless card

6. If you are using DHCP to obtain IP, then use dhclient or DHCPCD to obtain the IP

Dhclient Wlan0 or DHCPCD wlan0

Now the wireless network card should be able to use normally.
