How to Check if your Raspberry Pi is Connected to WiFi

There are several ways to check if your Raspberry Pi is connected to a wireless network. This article will guide you through three methods that you can use to verify your Raspberry Pi’s connection status and get useful information about the WiFi network it is connected to.

Method 1: Using nmcli command-line tool

nmcli (Network Manager Command Line Interface) is a powerful command-line tool for managing network connections on Linux systems, including Raspberry Pi. To check if your Raspberry Pi is connected to a WiFi network using nmcli, follow these steps:

1. Open the terminal on your Raspberry Pi.
2. Type the following command and press Enter:

nmcli device wifi list

3. This will display a list of available wireless networks. Look for your network’s SSID (Service Set Identifier) in the list. If you see it, then your Raspberry Pi is connected to that WiFi network.
4. To get more detailed information about the connection status, use this command:

nmcli device show wlan0

Here, wlan0 is the name of the wireless network interface on most Raspberry Pi models. Replace it with the correct name if yours is different (e.g., wlp2s0). The output will include connection status, IP address, signal strength, and other details about your WiFi connection.

Method 2: Using iwconfig command-line tool

iwconfig is another useful command-line tool for checking wireless network connections on Linux systems. To check if your Raspberry Pi is connected to a WiFi network using iwconfig, follow these steps:

1. Open the terminal on your Raspberry Pi.
2. Type the following command and press Enter:

iwconfig

3. This will display information about all network interfaces, including wireless ones. Look for your network’s SSID under the ESSID field. If you see it, then your Raspberry Pi is connected to that WiFi network.
4. To get more detailed information about the connection status, use this command:

iwconfig wlan0

Here, wlan0 is the name of the wireless network interface on most Raspberry Pi models. Replace it with the correct name if yours is different (e.g., wlp2s0). The output will include connection status, IP address, signal strength, and other details about your WiFi connection.

Method 3: Using the GUI Network Manager

If you prefer a graphical user interface to check your Raspberry Pi’s WiFi connection status, you can use the built-in Network Manager applet. Follow these steps:

1. Click on the network icon in the top right corner of your Raspberry Pi desktop.
2. Select “Connection Information” from the menu that appears.
3. This will display information about your current WiFi connection, including the SSID, IP address, and signal strength. If you see your network’s SSID, then your Raspberry Pi is connected to it.
4. You can also use this interface to connect to a new WiFi network or edit the settings of an existing connection.

In summary, there are several ways to check if your Raspberry Pi is connected to a WiFi network. The nmcli and iwconfig command-line tools provide detailed information about the connection status, while the GUI Network Manager offers a user-friendly interface for quick verification. Regardless of which method you choose, remember that it’s essential to ensure your Raspberry Pi is connected to a WiFi network before attempting to use internet-based services or applications.
