== wifi Wifi == In this example, we will connect to an Access Point.* First of all, we must disable Soft Blocking on the wlan0 interface via rfkill:<pre>rfkill unblock 0</pre> * Then we can set the interface up:<pre>ifconfig wlan0 up</pre> * We can scan for Access Points if we don't know its exact SSID:<pre>iw wlan0 scan</pre> * Then we proceed to connect to our Access Point: :*In case our Access Point is WPA secured, we can use wpa_supplicant to connect. For this purpose, we should configure /etc/wpa_supplicant.conf file:<pre>network={ ssid="ISEE Tech" proto=WPA2 key_mgmt=WPA-PSK psk="Idkfa2009"}</pre> :To start the supplicant, we specify the interface, the configuration file and the driver to be used. In this case:<pre>wpa_supplicant -Dnl80211 -i wlan0 -c wpa_supplicant.conf</pre> :*On the other hand, if it is a WEP secured Access Point, you must enter the next command. If your AP doesn't have a password, omit the key part:<pre>iw wlan0 connect IGEP_example key 0:12345</pre> *After a few seconds, the link should be established. We can now check the connection pinging a known server, for example:<pre>ping www.google.com</pre>
