How to setup Wi-Fi dongle on Raspberry Pi

Hi,

in order to enable the wi-fi dongle it’s necessary follow these steps:

1. Edit the file “interfaces”:
   
   sudo nano /etc/network/interfaces
   add the follow strings
   
   allow-hotplug wlan0iface wlan0 inet dhcpwpa-conf /etc/wpa_supplicant/wpa_supplicant.confiface default inet dhcp
   below the screeshot:
   
   
2. Edit the file “wpa_supplicant.conf” with the command:
   
   sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
   Add the follow strings
   
   network={
   ssid="YOURSSID"
   psk="YOURPASSWORD"
   # Protocol type can be: RSN (for WP2) and WPA (for WPA1)
   proto=WPA
   # Key management type can be: WPA-PSK or WPA-EAP (Pre-Shared or Enterprise)
   key_mgmt=WPA-PSK
   # Pairwise can be CCMP or TKIP (for WPA2 or WPA1)
   pairwise=TKIP
   #Authorization option should be OPEN for both WPA1/WPA2 (in less commonly used are SHARED and LEAP)
   auth_alg=OPEN
   }
   
   below the screeshot:
3. When editing files is done, is the time to run the command: sudo reboot .Immediately after run the command,  unplug the Ethernet cable and plug in the Wi-Fi dongle.
