Step-by-Step to connect to WiFi in Kali Linux

Connecting to WiFi in Kali Linux can be a little difficult than other operating systems, especially for users who are new to Linux. Kali Linux, is well known for its advanced penetration testing capabilities, and it also comes with basic features like wireless connectivity.

Connecting to WiFi is essential for accessing updates, downloading tools, and conducting online research.

In this article, we’ll walk you through the process of connecting to WiFi in Kali Linux, using both the graphical interface or the command line.

Method 1: Connecting to WiFi Using the Graphical User Interface (GUI)

For most users, the simplest way to connect to WiFi is through Kali Linux’s graphical user interface. Here’s how:

Step 1: Open the WiFi Settings

  1. Look for the network icon in the top-right corner of the screen. It should look like a WiFi signal or an Ethernet symbol if you’re currently using a wired connection.
  2. Click on the network icon to see a list of available WiFi networks.

Step 2: Select a WiFi Network

  1. From the list of available networks, select the WiFi network you want to connect to.
  2. A pop-up window will appear, prompting you to enter the WiFi password.

Step 3: Enter the Password

  1. Type in the WiFi password for the network you selected.
  2. After entering the password, click Connect.

Once connected, the network icon will show a signal indicating that you’re online. Your device will automatically connect to this network in the future, as long as the network settings are not changed.

Method 2: Connecting to WiFi Using the Command Line

While the GUI method is simpler, some users prefer connecting via the command line, especially when managing remote servers or working without a graphical interface. Follow these steps to connect to WiFi using the terminal:

Step 1: Check Available Network Interfaces

First, you need to know your wireless interface name. Open the terminal and type:

iwconfig

This command will show you all network interfaces. Look for the interface with wlan0 or something similar. This is your wireless interface.

Step 2: Scan for Available WiFi Networks

Once you know the interface name, you can scan for available networks using the following command:

sudo iwlist wlan0 scan | grep SSID

This command will display the available WiFi networks, filtering by SSID (the name of the WiFi network).

Step 3: Connect to a WiFi Network

To connect to a specific WiFi network, use the nmcli tool, which comes pre-installed in Kali Linux. Run the following command:

nmcli d wifi connect [SSID] password [WiFi password]

Replace [SSID] with the name of the WiFi network and [WiFi password] with the actual password of the network.

For example, if your network SSID is “AIRTEL5G” and the password is “12345678”, the command would look like this:

nmcli d wifi connect AIRTEL5G password 12345678

Step 4: Verify Your Connection

Once you’ve connected, you can verify the connection by typing:

nmcli connection show

You should see the WiFi network you’re connected to listed here. Additionally, you can check your network’s IP address by typing:

ifconfig

The wireless interface (wlan0) should display an IP address, confirming that you are connected to the internet.

Troubleshooting WiFi Connection Issues

If you’re having trouble connecting to WiFi, here are some common issues and solutions:

1. WiFi Not Detected

  • Solution: Ensure that your wireless adapter is enabled. You can check this by running rfkill list and looking for the “Soft blocked” or “Hard blocked” status. If it’s blocked, unblock it by typing:
rfkill unblock all

2. Incorrect WiFi Password

  • Solution: Double-check the WiFi password. If you’re using the command line, ensure there are no typos in the SSID or password. If necessary, re-enter the password using the GUI.

3. WiFi Adapter Not Recognized

  • Solution: If your WiFi adapter isn’t recognized, you may need to install the necessary drivers. You can install drivers for most adapters using the following command:
sudo apt-get install firmware-linux-nonfree

After installing the drivers, reboot your system and try connecting to the WiFi network again.

4. Check Network Manager

  • Solution: Ensure that the network manager is running by typing the following command:
sudo systemctl start NetworkManager

You can also enable it to start automatically at boot:

sudo systemctl enable NetworkManager

By following these steps, you’ll be able to connect your device to a wireless network in no time, ensuring that you have access to the internet for updates, downloads, and other online activities.

For those new to Linux or networking, understanding how to manage connections through the command line can be a valuable skill, especially when using Kali Linux for penetration testing or server management.
