Router Extension Without Having to Log in Again

One of the first things you lot'll want to exercise with your Raspberry Pi is definitely to configure the WiFi.

Today, we'll bear witness y'all three ways to configure WiFi on your Raspberry Pi with both Raspberry Pi OS desktop and server. We'll also comprehend how to exercise it on a headless Raspberry Pi!

Wired Ethernet Connection

To prepare a wired net connection, only connect your Raspberry Pi to the back of your network router with an ethernet or RJ45 cable. Once plugged in, you should find the network LED blinking on your Raspberry Pi.

In almost cases, your wired internet connexion will now be upwards and ready for use, provided that your router has DHCP enabled. DHCP stands for Dynamic Host Configuration Protocol, and basically assigns IP addresses to devices that connect to your router.

To enable DHCP, admission your home router'south management console with another computer that has already been connected. You tin typically do this past entering your router's IP address into the address bar of any internet browser.

For more details, Computer Hope has a free and detailed guide here.

Wireless Connection – WiFi Hardware

To fix a WiFi connection, we will showtime need a WiFi module for our Raspberry Pi. Fortunately, all Raspberry Pi models from the Raspberry Pi 3 Model B (2016) and later transport with on-board WiFi. If you have an older model on hand, or if your on-board WiFi module is not operation, you will need to apply an external USB WiFi adapter.

When choosing a WiFi adapter, ensure that there is commuter support. For instance, WiFi adapters with the RTL8192cu chipset will work readily since there is Raspberry Pi Bone support built in.

Another consideration is the power depict. WiFi can crave a lot of power, especially if a heavy amount of data is being transmitted. For older Raspberry Pi in item, you may require an external ability supply similar a powered USB hub to power the WiFi adapter.

For more details on selecting a suitable USB WiFi adapter, you can read this page on eLinux.org. They also have a list of compatible WiFi adapters for the Raspberry Pi!

[Updated Mar 2021] The Just Method You Need to Set up Raspberry Pi WiFi!

With a new update to the Raspberry Pi Imager, it's become easier than e'er to set up your Raspberry Pi's WiFi connection, regardless of if yous're going for a headless setup or not. Let's become started!

Footstep ane: Install the latest version of the Raspberry Pi Imager for your operating organization here.

Step 2: Open the Raspberry Pi Imager. You should be greeted with the aforementioned screen as always.

Footstep three: Press Ctrl + Shift + x to open the advanced menu (CMD + Shift + x for Mac OSX).

Step 4: Scroll down to Configure wifi, check the box and enter your WiFi credentials.

Annotation: Be sure to change your Wifi country according to your country code!

Footstep 5: Click Salve and flash your Bone to your microSD card for your Raspberry Pi! That's it!

There are too other settings in the Advanced options carte that you tin can explore. For example, y'all can plow on SSH for easier headless installations and even configure the hostname of your Raspberry Pi!

Other Methods to Set up Up Raspberry Pi Wi-Fi

The methods shared in the following sections are still valid and volition piece of work for setting upward the Wi-Fi on your Raspberry Pi. However, I recommend you follow the latest method every bit y'all'll find it much easier!

Method i: Configure WiFi with Raspberry Pi Bone GUI

For users running Raspberry Pi Os Desktop on their Raspberry Pi, you can simply utilize the provided GUI to set up your WiFi connection. This works just as you'd expect it to with your other laptops or smartphones.

Method 2: Configure WiFi from Command Line with Raspi-Config

If yous are running a server distribution of Raspberry Pi OS without a GUI, you will have to apply Raspi-Config instead. This method works in Raspberry Pi Bone Desktop equally well.

Raspi-Config is a console based application used to configure diverse settings on the Raspberry Pi. Information technology tin be used for network configuration, setting up remote access, kick options etc.

To open Raspi-Config northward the command line, type the command:

                sudo raspi-config

Using the pointer keys on your keyboard, navigate to "Network Options" and press Enter.

Select Wi-fi, so follow the on-screen instructions to enter your network'southward SSID and password. When you're done, select "Stop" on the main menu to close Raspi-Config.

Finally, reboot the Raspberry Pi to apply the settings we've just changed. Your WiFi connectedness should and then be good to get!

Configuring WiFi on a Headless Raspberry Pi

A headless Raspberry Pi is one that nosotros would like to run without a monitor, keyboard, or mouse. As you can imagine, it won't be as straightforward to use the methods nosotros've covered and so far.

Enable SSH (Secure Shell)

For this section, we will first want to enable SSH on our Raspberry Pi. This is something that yous'll want to do if you're running your raspberry pi headless anyway.

With SSH, yous can use an internet connexion to remotely run terminal commands on the Raspberry Pi from your primary computer through an cyberspace connection.

To enable SSH on a headless Raspberry Pi, simply place a file named "ssh", without any extension, onto the boot partition of the SD card from another reckoner. This volition tell Raspberry Pi to enable SSH when booting. The content of the file does not matter.

Note: Do not connect your Raspberry Pi directly to a public network if yous have not even so set up secure passwords for all users. Your device may be compromised by hackers.

Method 1: Enable WiFi Via Ethernet Cable

This method involves using an ethernet connection to utilise SSH for setting upward our WiFi.

Once our ethernet connection is established via wired connexion with our router, refer to the DHCP allotment table on your router management panel to obtain the IP address of your Raspberry Pi.

One time we take obtained the IP address, we can use any SSH client such as PuTTY on Windows to admission the Raspberry Pi. Linux and MacOS users tin can utilise SSH without any additional software.

On Linux or MacOS, merely enter the post-obit control with the <IP> for your device.

                ssh [electronic mail protected]<IP>

In one case the connection is successful, we can simply utilise:

                sudo raspi-config

to configure our WiFi connexion like nosotros covered before!

Method 2: Enable Wifi via wpa_supplicant

This method involves replacing the wpa_supplicant.conf file on our Raspberry Pi to provide our WiFi configuration.

First, y'all'll want to create a wpa_supplicant.conf file with the post-obit content. You can practise this with whatsoever text editor.

                ctrl_interface=DIR=/var/run/wpa_supplicant Grouping=netdev update_config=1 country=<Country Code>  network={      ssid="<SSID>"      psk="<Password>"      scan_ssid=ane }

Retrieve to supplant <Country Code>, <SSID>, and <Countersign> with your own land code, WiFi SSID and password.

So, mountain your SD card with Raspberry Pi OS onto your calculator and copy the wpa_supplicant.conf file to the root of the /boot division of your SD card. Similar to how nosotros enabled SSH, the file will be used on kicking to apply our new WiFi settings to our Raspberry Pi.

Since we are going entirely headless, information technology tin can be hard to troubleshoot this method of Wifi configuration. If it doesn't work the commencement time, cheque and ensure that the name of your wpa_supplicant.conf file and its contents are correct before trying over again.

Once nosotros successfully configure our WiFi connexion using either method above, we tin can now use SSH over WiFi to interface with our Raspberry Pi's command line!

Test Your WiFi Connexion

Cheque IP Accost

To ensure that our WiFi connectedness has been established correctly, first unplug your ethernet cablevision. Nosotros tin check our IP accost through the command line with:

                ifconfig wlan0

Next to "inet", nosotros should see our IP address, which indicates a successful connection.

Ping a Website

Adjacent, nosotros can check if our WiFi connection successfully allows the states to send and call back data to and from our favourite websites. Try ping google.com to see if you can attain information technology!

Summary

We've shown you a number of ways that you lot can configure the WiFi on the Raspberry Pi!

If you're just getting started with your Pi, consider setting it upwards as a VPN server! Visit our weblog to learn how to ready a Raspberry Pi VPN server using PiVPN and browse securely on public networks.
