11.5.2 Setting Wireless Connection with Configuration File
The default settings for the network in the Raspberry Pi system are stored in the file "/etc/network/interfaces". In this file, you can activate the wireless connection by directly entering the settings for the wireless connection.
If you have already configured with the window Wi-Fi configuration tool, it will have the following contents, and you will need to delete all this contents.
| allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp |
To configure for wireless connection, you need to enter the following in the configuration file. Of course, "ssid" and "psk" must be entered as pre-defined in the access point.
| iface wlan0 inet dhcp wpa-ssid "wifissid" wpa-psk "wifipassword" |
When the setup is completed, execute the following command to stop and restart the wireless device again.
