How to Connect Wi-Fi on Linux Mint: A Step-by-Step Guide

Transition to an operating system Linux Mint It's often a welcome revelation for users seeking stability and lightweight functionality, but the first obstacle to fully functional operation is the lack of an internet connection. Unlike Windows, where drivers are often built-in or installed automatically, in the open source world, manual intervention is sometimes required, especially if you don't have an Ethernet cable installed. Modern versions of the distribution, such as Linux Mint 21, are based on Ubuntu 22.04 LTS and have excellent hardware support, but the nuances of network configuration can still be confusing for a beginner.

In this guide, we'll cover all aspects of connection: from simple network selection in the graphical interface to complex terminal manipulations when automatic tools fail. You'll learn how to check the status of your wireless adapter, install proprietary drivers, and configure a static IP address if automatic distribution is unavailable. DHCP It's not working. It's important to understand that successful setup depends not only on the system version but also on the chipset of your Wi-Fi module, so we'll cover hardware diagnostic methods.

Don't panic if the network icon shows "Device not ready" or the network list is empty. This is normal for some adapter models that require loading additional kernel modules. We'll look at the tools. nmcli And nmtui, which allow you to manage connections even without a graphical shell. Critical to this is having access to the repositories to install drivers, which often requires a temporary connection via a USB modem or Ethernet cable.

Checking the compatibility and condition of the equipment

Before you begin configuring, you need to make sure the operating system can see your wireless adapter. In Linux, hardware and software drivers are separate, and a lack of network visibility often indicates that the kernel hasn't loaded the required module. For initial diagnostics, use the utility lspci for internal cards or lsusb For external USB dongles, launch the terminal and enter the command lspci -k | grep -A 3 -i networkto see which driver is currently being used.

If you see the line in the command output Kernel driver in use, which means the driver is active, and the problem most likely lies in the configuration settings or radio module blocking. If this line is missing, and only Kernel modules, the module exists but isn't loaded and must be activated manually. Sometimes the adapter may be software-blocked, in which case the system will display the "Hard Blocked" or "Soft Blocked" status.

⚠️ Note: If you are using a laptop, check the physical Wi-Fi switches on the case or the key combinations with FnIn Linux, soft blocking is often caused by a power management conflict, which can be resolved with the command sudo rfkill unblock wifi.

For a more in-depth analysis, you can use the utility inxi, which provides summary information about the system. The command inxi -N will show network devices and the drivers used. If the adapter is not displayed in any lspci, not in lsusbIt may be physically faulty or disabled in the BIOS/UEFI. In rare cases, a kernel update is required to support the latest hardware.

Connecting via the NetworkManager graphical interface

In most cases, connecting to a wireless network is Linux Mint does not require entering complex commands, as it is responsible for this NetworkManagerIn the lower right corner of the screen, in the system tray, there's a network icon (usually two arrows or a signal indicator). Clicking it opens a menu that should display a list of detected Wi-Fi networks. If the list is empty, make sure the Wi-Fi switch is turned on.

Select your network from the list and click on it. If the network is password-protected, a window for entering the security key will appear. It's important to select the correct encryption method, although the system usually detects it automatically. For home networks, the standard is WPA/WPA2-PersonalAfter entering the password, the system will attempt to obtain an IP address via DHCP and configure DNS servers automatically.

In some cases, such as corporate networks or when using hidden SSIDs, manual configuration may be required. Click "Connect to a hidden network" or select "Network settings" to create a new profile. Here you can set a static IP address if your router doesn't assign addresses automatically, or specify specific DNS servers, such as 1.1.1.1 from Cloudflare.

Once connected, the tray icon will change to show the signal strength. You can click it again to view connection details, including link speed and assigned IP address. If the connection is successful but the internet isn't working, the issue may be with your ISP or DNS settings, not the connection to the router itself.

Working with the terminal: nmcli and nmtui utilities

The graphical interface is convenient, but in server versions or during crashes X11/Wayland The only tool left is the terminal. The main utility for network management is nmcli (NetworkManager command line interface). First, you should display a list of available devices with the command nmcli device. Status connected means work, disconnected — the device is ready, but not connected, and unavailable - lack of driver or cable.

To scan networks, use the command nmcli device wifi listIt will show all available access points within range. To connect, enter the following command: nmcli device wifi connect "Network_Name" password "Your_Password"Please note that the network name and password are case sensitive, and spaces in the network name must be enclosed in quotation marks.

nmcli device wifi connect"HomeWiFi" password"SuperSecretPass123"

For those who prefer a pseudo-graphical interface, there is a utility nmtuiRun it with the command sudo nmtui (or simply nmtui (In some configurations). A text menu will open where you can select "Activate a connection," find your network in the list, and enter the password. This is ideal for beginners wary of syntax errors in the command line.

Installing drivers via Driver Manager

One of the most common reasons for Wi-Fi not working on Linux Mint is the lack of proprietary drivers for wireless cards Broadcom or RealtekFortunately, the distribution includes a convenient built-in tool called "Driver Manager," which automatically scans your hardware and suggests available solutions. You can find it in the main menu by searching for "Drivers."

Launch the program and wait for the scan to complete. If the system finds suitable drivers, they will be displayed in a list with radio buttons for selection. You need to select the recommended driver (usually marked as recommended) and click "Apply Changes." The process will take a few minutes as the packages are downloaded from the repositories.

After installing the drivers, be sure to restart your computer. In some cases, especially with modules DKMS (Dynamic Kernel Module Support) is a kernel module that is compiled specifically for your kernel version during installation. Without a reboot, the new module may fail to load, and the adapter will remain inactive.

Devices from Broadcom historically require special attention in the Linux world. If the "Driver Manager" doesn't help, you can try installing the package manually. Older cards often require a package bcmwl-kernel-source, and for new ones - firmware-b43-installerInstallation is performed via the terminal using the command sudo apt install bcmwl-kernel-source.
