Wpa_supplicant Download Windows

.Important note to pay attention to. You'll most likely use eth0 on a USG and eth2 or eth3 on a USG-Pro, edit the files accordingly. Do not run the supplicant on virtual interfaces (e.g. Eth0.0), as it will not work. This tool is used to create your 'wpasupplicant.conf' for use with Pi-Star. All you need to do is enter your SSID (this is the name of your Wireless Network) and the matching PSK (this is the Pre-Shared Key, or Password) for this network, when you hit 'Submit' the generated config file will download to your computer.

This method is suitable if you don't have access to the graphical user interface normally used to set up a wireless LAN on the Raspberry Pi. 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.

Using raspi-config

The quickest way to enable wireless networking is to use the command line raspi-config tool.

sudo raspi-config

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.

Getting wireless LAN network details

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:

'ESSID:'testing' is the name of the wireless network.
'IE: IEEE 802.11i/WPA2 Version 1' is the authentication used. In this case it's WPA2, the newer and more secure wireless standard which replaces WPA. This guide should work for WPA or WPA2, but may not work for WPA2 enterprise. For WEP hex keys, see the last example here. You'll also need the password for the wireless network. For most home routers, this is found on a sticker on the back of the router. The ESSID (ssid) for the examples below is testing and the password (psk) is testingPassword.

Adding the network details to the Raspberry Pi

Open the wpa-supplicant configuration file in nano:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Go to the bottom of the file and add the following:

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 use the wpa_passphrase utility to generate an encrypted PSK. This takes the SSID and the password, and generates the encrypted PSK. With the example from above, you can generate the PSK with wpa_passphrase 'testing'. Then you will be asked for the password of the wireless network (in this case testingPassword). The output is as follows:

Note that the plain text version of the code is present, but commented out. You should delete this line from the final wpa_supplicant file for extra security.

The wpa_passphrase tool requires a password with between 8 and 63 characters. To use a more complex password, you can extract the content of a text file and use it as input for wpa_passphrase. Store the password in a text file and input it to wpa_passphrase by calling wpa_passphrase 'testing' < file_where_password_is_stored. For extra security, you should delete the file_where_password_is_stored afterwards, so there is no plain text copy of the original password on the system.

To use the wpa_passphrase–encrypted PSK, you can either copy and paste the encrypted PSK into the wpa_supplicant.conf file, or redirect the tool's output to the configuration file in one of two ways:

Either change to root by executing sudo su, then call wpa_passphrase 'testing' >> /etc/wpa_supplicant/wpa_supplicant.conf and enter the testing password when asked
Or use wpa_passphrase 'testing' | sudo tee -a /etc/wpa_supplicant/wpa_supplicant.conf > /dev/null and enter the testing password when asked; the redirection to /dev/null prevents tee from also outputting to the screen (standard output).

If you want to use one of these two options, make sure you use >>, or use -a with tee — either will append text to an existing file. Using a single chevron >, or omitting -a when using tee, will erase all contents and then append the output to the specified file.

Now save the file by pressing Ctrl+X, then Y, then finally press Enter.

Reconfigure the interface with wpa_cli -i wlan0 reconfigure.

You can verify whether it has successfully connected using ifconfig wlan0. If the inet addr field has an address beside it, the Raspberry Pi has connected to the network. If not, check that your password and ESSID are correct.

On the Raspberry Pi 3B+ and Raspberry Pi 4B, you will also need to set the country code, so that the 5GHz networking can choose the correct frequency bands. You can do this using the raspi-config application: select the 'Localisation Options' menu, then 'Change Wi-Fi Country'. Alternatively, you can edit the wpa_supplicant.conf file and add the following. (Note: you need to replace 'GB' with the 2 letter ISO code of your country. See Wikipedia for a list of 2 letter ISO 3166-1 country codes.)
