Configuring WIFI via Command Line
The RaspberryPi Wireless WiFi Dongle Configuration guide by Farnell is THE BEST i’ve found so far.
To check if your wifi dongle is recognized
ifconfig
if you see wlan0, it confirms that raspberry pi has detected your wifi adaptor.
To scan for wifi networks
sudo iwlist wlan0 scan
Edit the wpa_supplicant.conf
file
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
Add the following with your network details at the end of the file, below update_config=1
.
network={
ssid=“Area 51"
psk=“password"
key_mgmt=WPA-PSK
}
To add another network, just add the same code with details specific to the network you want to add.
