Prerequisites Before You Begin

Before diving into the steps for how to enable WiFi on Ubuntu?, it helps to confirm a few basics. Taking a moment to check these items can save you time later.

  • A working WiFi adapter: Most laptops have a built-in wireless card. Desktop users may need a USB WiFi adapter or a PCIe wireless card.
  • Ubuntu installed and running: These instructions apply to recent Ubuntu versions, including Ubuntu 20.04, 22.04, 24.04, and newer releases.
  • Administrative access: Some steps require sudo privileges to install drivers or modify network settings.
  • Optional wired connection: If your WiFi drivers are missing, a temporary Ethernet connection or a USB tether from your phone can help you download what you need.

Once you have confirmed these prerequisites, you can move on to checking whether Ubuntu recognizes your wireless hardware.

How to Check if Your WiFi Hardware Is Detected

Ubuntu cannot enable WiFi if it does not detect a wireless adapter. Checking hardware detection is a smart first step, especially if the WiFi option is missing from your system menu.

Check with the Terminal

Open the Terminal by pressing Ctrl + Alt + T and run one of the following commands:

lspci | grep -i network

This command lists PCI network devices. If you see a wireless controller in the output, Ubuntu recognizes the hardware. For USB WiFi adapters, use:

lsusb

You can also check the status of your network interfaces with:

ip link show

Look for an interface named something like wlan0, wlp2s0, or wlo1. If such an interface appears, your system has detected a wireless device.

Check with the System Information Tool

If you prefer a graphical approach, open Settings, go to About or System Details (depending on your Ubuntu version), and review the hardware information. This can confirm whether the system sees your network card.

How to Enable WiFi on Ubuntu Using the Graphical Interface

For most desktop users, the easiest way to learn how to enable WiFi on Ubuntu? is through the graphical interface. Ubuntu’s GNOME desktop provides a simple network menu in the top-right corner of the screen.

Step-by-Step: Using the System Menu

  1. Click the system menu in the top-right corner of the screen (where you see icons for network, sound, and power).
  2. Look for the WiFi section. If WiFi is turned off, you may see an option labeled Wi-Fi Off or a toggle switch.
  3. Click the WiFi option to expand it, then click Turn On or toggle the switch to the on position.
  4. Once WiFi is enabled, click Select Network to view available networks.
  5. Choose your network name (SSID) from the list.
  6. Enter the network password when prompted and click Connect.

If the connection is successful, the WiFi icon in the top bar will change to indicate signal strength. You should now be online.

Step-by-Step: Turning On WiFi in Ubuntu Settings

If the quick system menu does not show the options you need, you can enable WiFi through the full Settings application. This method gives you more control over network configuration.

  1. Open the Activities overview by pressing the Super key (usually the Windows key) or by clicking Activities in the corner.
  2. Type Settings and open the Settings app.
  3. In the left sidebar, click Wi-Fi (sometimes labeled Network depending on your version).
  4. Make sure the WiFi toggle at the top of the window is switched on.
  5. Wait a few seconds for Ubuntu to scan for available networks.
  6. Click the name of the network you want to join.
  7. Enter the security key (password) and click Connect.

You can also click the gear icon next to a connected network to view details such as IP address, DNS settings, and security type. This is useful if you need to troubleshoot or configure advanced options.

How to Enable WiFi on Ubuntu Using the Terminal (nmcli)

The terminal offers a powerful way to manage WiFi, especially on systems without a graphical interface or when troubleshooting. The nmcli command is part of NetworkManager and is available on most Ubuntu installations.

Check WiFi Status

nmcli radio wifi

This command tells you whether WiFi is enabled or disabled.

Turn WiFi On

nmcli radio wifi on

List Available Networks

nmcli device wifi list

Connect to a Network

nmcli device wifi connect "YourNetworkName" password "YourPassword"

Replace YourNetworkName and YourPassword with your actual network credentials. If the network name contains spaces, keep the quotation marks.

Verify the Connection

nmcli connection show --active

Using nmcli is one of the fastest answers to how to enable WiFi on Ubuntu? when you are working from the command line or connected via SSH.

How to Enable WiFi on Ubuntu Using nmtui

If you prefer a text-based interface that is easier to navigate than raw commands, nmtui (NetworkManager Text User Interface) is a great option. It provides a simple menu-driven experience inside the terminal.

Steps to Use nmtui

  1. Open the Terminal.
  2. Run the command: nmtui
  3. Select Activate a connection from the menu.
  4. Choose your WiFi network from the list of available connections.
  5. Press Enter to activate it.
  6. Enter the password if prompted.

If nmtui is not installed on your system, you can install it with:

sudo apt update
sudo apt install network-manager

This tool is especially helpful on minimal Ubuntu installations or servers where a full desktop environment is not available.

Using rfkill to Unblock WiFi

Sometimes WiFi appears to be enabled in software but remains unavailable because it is blocked at the hardware or software level. The rfkill tool helps you check and remove these blocks.

Check for Blocks

rfkill list

The output shows whether your wireless device is soft blocked (blocked by software) or hard blocked (blocked by a physical switch or BIOS setting).

Unblock WiFi

sudo rfkill unblock wifi

After running this command, try enabling WiFi again using the Settings app or nmcli. If the device is hard blocked, check your laptop for a physical WiFi switch or a function key combination (such as Fn + F2) that toggles the wireless radio. You may also need to enable wireless in your system’s BIOS or UEFI settings.

How to Install WiFi Drivers on Ubuntu

If Ubuntu detects your WiFi card but cannot use it, or if no wireless option appears at all, you may need to install the correct driver. This is a common issue with certain Broadcom and Realtek chipsets.

Use Additional Drivers (Graphical Method)

  1. Connect to the internet temporarily using an Ethernet cable or USB tethering.
  2. Open Software & Updates from the Activities menu.
  3. Go to the Additional Drivers tab.
  4. Wait for Ubuntu to search for available drivers.
  5. Select the recommended proprietary driver for your wireless device.
  6. Click Apply Changes and enter your password.
  7. Restart your computer after the installation completes.

Install Drivers from the Terminal

You can identify your wireless chipset and install common driver packages using the terminal:

sudo ubuntu-drivers devices
sudo ubuntu-drivers autoinstall

For some Broadcom cards, the following package is often needed:

sudo apt update
sudo apt install bcmwl-kernel-source

After installing drivers, reboot your system and check whether WiFi is now available. Driver installation is often the key step in solving how to enable WiFi on Ubuntu? on laptops with proprietary wireless hardware.
