It is particularly suitable for use with a serial console cable if you don't have access to a screen or wired Ethernet network. Note also that no additional software is required; everything you need is already included on the Raspberry Pi. The quickest way to enable wireless networking is to use the command line raspi-config tool. Select the Localisation Options item from the menu, then the Change wireless country option. On a fresh install, for regulatory purposes, you will need to specify the country in which the device is being used.
Then set the SSID of the network, and the passphrase for the network. If you do not know the SSID of the network you want to connect to, see the next section on how to list available networks prior to running raspi-config. Note that raspi-config does not provide a complete set of options for setting up wireless networking; you may need to refer to the extra sections below for more details if raspi-config fails to connect the Pi to your requested network.
To scan for wireless networks, use the command sudo iwlist wlan0 scan. This will list all available wireless networks, along with other useful information. Look out for:.
The password can be configured either as the ASCII representation, in quotes as per the example above, or as a pre-encrypted 32 byte hexadecimal number. You can find Raspberry Pi's on your network using their hostname followed by. But to do that in Windows you have to install the Bonjour service first. If you have iTunes installed on Windows you probably don't have to do this. But if you don't, browse to:. Download Bonjour Print Services for Windows v2.
If you can't connect, see the troubleshooting section near the end of this article. You may need to make some adjustments for your network. Select the options for changing the hostname and password.
On a new image, I would also recommend expanding the file system now under the Advanced options. Once the changes are made, reboot. Remember that once you reboot, you will need to use the new hostname to login over ssh.
For example, if your new hostname is mypi you would connect like this on a Mac:. After booting, once you choose your language and country, you will be taken to a window like this:.
Just in case you missed the welcome wizard or this is not your first boot, you can configure and connect at any time from the taskbar. For this:. If you are running on the Raspbian Lite version, then you may need some additional help you find out and configure the WiFi properly. On Raspbian Lite, there are 2 methods by which you can do the same. The raspi-config is a great tool available on Raspbian by default.
This will help you configure your wireless network with ease. Your Pi will now connect to the WiFi network and you can proceed with that. This method is a bit difficult but may be useful for connecting to big networks that need secure authentication or other complexities. For this, you can use this command:. This will open the file and you can see the same content as we have seen in method 1.
If you are interested, you can refer to some more examples here to adapt the configurations to your network for security options like WEP, EAP, etc. Now, when coming to the network configuration, if you wish to set a static IP on your network, the configuration can be performed in dhcpcd. Type this command to open the file:.
