Benefits of Wi-Fi in Raspberry Pi 4

In modern days, it is impossible to think of a device without wireless connectivity, especially when it comes to accessing the internet. Hence, the built-in wifi feature in the portable but fully capable computing device has added a new dimension for the users.

Firstly, if you are not fond of excess heavy wirings, this specification will surely bring a smile to your face. You can completely avoid the ethernet port for getting access to the internet. The universal compatible wi-fi adapter is suitable for using the internet in any network band.

Besides, a wifi feature increases the versatility and portability of the Raspberry Pi 4. You can easily set up your workstation in any part of the home/office space. The hassle of using the ethernet cable becomes optional that way.

As a general user, the availability of the dual-band (2.4GHz and 5GHz) ensures working with high-speed internet, even if it is for streaming or any DIY work.

How To Configure Wi-Fi On Raspberry Pi 4?

There are various methods to connect your Raspberry Pi 4 to an existing wifi network. Follow the below-mentioned methods to select the most suitable one for you.

Method 1: Using The Raspberry Desktop Application

This is the simplest way to connect your Raspberry Pi 4 to Wi-Fi. It is for you if you use the Raspberry Pi as an independent setup with a mouse, keyboard, and a monitor like a desktop.

Step 1: Setting Up Your Raspberry Pi 4

A fresh out of the box, Raspberry Pi 4 requires an active Operating system to function like a simple desktop/laptop. You should have a micro SD card formatted at first. You can do it easily using any SD card reader and a laptop.

Setting Up Your Raspberry Pi 4

Secondly, download and install the official Raspberry Pi OS (NOOBS files) from the Raspberry website. Copy all the files to the SD card, which is a BOOT source for your device.

Step 2: Setting Up Your Wi-Fi

Once you have successfully installed the OS on your SD card, insert it into your Raspberry Pi. After that, connect it with a monitor, power source, mouse, and keyboard, followed by booting up the device.

You will automatically get the wifi connectivity option after the first startup. All you need is to select the SSID and input the password to get it connected.

Setting Up Your Wi-Fi

If, for some reason, you have skipped this part, you can manually open the wifi settings from the OS. Tap on the Raspberry icon and select “Internet.” Choose the preferred SSID and input the password for easily connecting to the wifi.

Method 2: Using Wi-Fi Configuration File

If you want your Raspberry Pi 4 to connect automatically to a specific Wi-Fi, this method is for you. You need not connect a mouse or keyboard to the device for this.

Step 1: Setting Up Configuration File

First, insert the SD card into your desktop/laptop. After that, open up the boot file. Now you need to create the configuration file by generating a text file. Create a text file and name it “WPA_supplicant.conf” after removing the file’s extension.

Step 2: Inputting Wi-Fi Credentials

Now open the text file of the configuration in notepad and type in the command as shown in the image below. You must include the country code, SSID of your network, and password carefully in this step.

You can find the country code for wifi connections online. But ensure the source has proper authorization; otherwise, you cannot connect to the wifi.

Inputting Wi-Fi Credentials

The credentials will be transferred to your device memory in the first boot. After that, create a new text file in the boot folder and rename it “ssh.” Remove the extension file and save it as it is. This file will be automatically deleted after your device has been connected to the wifi for the first time.

rename it ssh

Lastly, reconnect the SD card in your Raspberry Pi 4 and boot it up without connecting the mouse, keyboard, and ethernet cable. The boot will take some time and will connect to the internet automatically.

Method 3: Connecting to wifi via another device

In this method, you can remotely set up the wifi in your Raspberry Pi 4 from a secondary desktop/laptop. For this, you would need the Putty software installed on your desktop/laptop.

Step 1: Selecting The SSID

Open the PUTTY software and login into your Raspberry Pi using the user id and password. After that, type in the command “sudo iwlist wlan0 scan.” This will show all the available SSID in the coverage.

Selecting The SSID

Step 2: Connecting To The Wi-Fi

In this step, you have manually input the SSID and WPA password for your wifi network. Type in the command: sudo wpa_passphrase “SSID” “PASSWORD” and hit enter.
