operating system Linux Mint It's deservedly considered one of the best options for users switching from Windows, thanks to its user-friendly interface and stability. However, as with any other operating system, setting up a network connection can be the first hurdle a user encounters after installing the distribution. More often than not, the problem lies not with the operating system itself, but with the lack of proprietary drivers for the wireless module or specific power-saving settings.
In this article, we'll cover all possible methods for activating a wireless network in detail, from simple steps in the graphical interface to advanced configuration methods via the terminal. You'll learn how to diagnose missing drivers, where to find them, and how to install them correctly so your laptop or PC can finally see available access points. Attention: Before starting work, make sure that the physical Wi-Fi switch on the device body (if there is one) is set to the "On" position.
The connection process may vary depending on the kernel version and the network manager used. In modern versions Linux Mint is used by default NetworkManager, which handles most tasks perfectly, but sometimes requires manual intervention. We'll cover situations where the system "sees" networks but doesn't connect, and cases where the Wi-Fi indicator is completely absent.
Diagnosing the status of a wireless adapter
Before taking any action, you need to determine whether the operating system even sees your wireless device. It's often the case that the adapter is physically functional, but is blocked by software or lacks the necessary software. The first step is to check the device's status through the graphical interface or basic commands.
Click the network icon in the system tray (usually two computers or a Wi-Fi symbol) in the lower-right corner of the screen. If the drop-down menu says "Enable Wi-Fi" and it's grayed out, try clicking it. In some cases, the system may prompt you to enable wireless networks globally. If the Wi-Fi icon is completely missing, this is a sure sign that the driver hasn't loaded or the device is blocked at the BIOS/UEFI level.
For a more in-depth diagnosis, you can use the built-in system information tool. Open the application menu and search for "System Info," or use the terminal. In the terminal, enter the command lspci (for internal cards) or lsusb (for USB dongles) will display a list of connected devices. If you see a line with the name of your adapter (for example, Realtek, Intel, Qualcomm Atheros), which means the device is detected at the hardware level.
- 📶 Check the tray indicator: is the wireless network icon lit?
- 🔌 Make sure the USB adapter is firmly inserted into the port (if using an external module).
- 💻 Use the command
lspcito check the visibility of the card by the motherboard. - 🔋 Disable airplane mode if it was accidentally activated in settings.
⚠️ Note: If the adapter is not displayed in any
lspci, not inlsusbIt may be disabled in the BIOS/UEFI or physically damaged. Check your BIOS settings in the "Peripherals" or "Onboard Devices" section.
Using the NetworkManager GUI
In most standard cases Linux Mint Provides a user-friendly graphical interface for managing network connections, hiding complex technical details from the user. If the drivers are installed correctly, the connection process takes just a few clicks. Click the network icon in the taskbar to open a menu of available connections.
In the list that opens, you'll see available wireless networks. Find your network name (SSID) and click it. If the network is password-protected, the system will ask for a security key. Enter the password and click "Connect." NetworkManager will attempt to establish a connection, and if successful, the icon will change to show the signal strength.
Sometimes manual configuration is required, for example, if the network is hidden or uses specific corporate security protocols. To do this, select "Network Settings" or "Connect to a hidden network." Here, you can manually enter the IP address, DNS servers, and other parameters if automatic DHCP acquisition isn't working correctly.
☑️ Checking the connection via GUI
It's important to note that in some cases, the system may "remember" a network with incorrect parameters. If the connection fails, find your network in the list of known networks, right-click (or use the settings) and select "Forget Network." Then try connecting again, entering the password.
Installing and updating drivers through "Device Drivers"
One of the most common reasons for Wi-Fi not working is the lack of proprietary drivers. Linux Mint has an excellent tool for automatically searching and installing such drivers, called "Driver Manager." This utility scans your hardware and suggests available third-party software options.
Open the application menu and search for "Drivers." Run the application as an administrator.rator (you will need to enter a password)The system will scan your hardware. If drivers are available for your Wi-Fi adapter, they will be displayed in the list. It's generally recommended to select the option labeled "recommended."
After selecting the desired driver, click "Apply Changes." The installation process may take a few minutes while the system downloads the necessary packages from the repositories. Once the installation is complete, be sure to restart your computer so that the new driver is loaded into the kernel.
- 🛠️ Launch "Device Drivers" from the application menu.
- 🔍 Wait until the hardware scan is complete.
- ✅ Select the recommended driver for your wireless adapter.
- 🔄 Restart your system after installation.
⚠️ Note: An active internet connection is required for the "Device Drivers" feature to work. If Wi-Fi isn't working, connect your computer to the router via an Ethernet cable or use a USB modem from your Android smartphone in tethering mode.
Setting up Wi-Fi via the terminal: commands and utilities
For users who prefer full control over the system, or in cases where the graphical interface is unresponsive, the terminal becomes an indispensable tool. The command line allows not only to diagnose problems but also to directly manage network interfaces. The basic utility for network management in Linux Mint is nmcli (NetworkManager command line interface).
First, check the status of the radio devices with the command nmcli radio wifiIf it says "disabled", enable Wi-Fi with the command nmcli radio wifi onTo see a list of available networks, use the command nmcli dev wifi listIt will show the SSID, signal strength, and security status.
nmcli dev wifi connect "Your_Network_Name" password "Your_Password"This command will attempt to connect the device to the specified network. If the connection is successful, you will see a message confirming the connection has been activated. It's also helpful to know the command ip link, which shows the status of all network interfaces. If the Wi-Fi interface (often called wlan0 or wlp2s0) marked as DOWN, it can be raised by the command sudo ip link set wlan0 up.
What to do if nmcli doesn't see the adapter?
If the nmcli dev wifi list command returns an empty list or an error, the NetworkManager service may be stopped. Try restarting it with the command: sudo systemctl restart NetworkManager. Also, check if the adapter is blocked with the rfkill list command.
Troubleshooting Broadcom and Realtek Drivers
Adapters from manufacturers deserve special attention. Broadcom And Realtek, which often require manual installation of packages. Unlike Intel, whose drivers are built into the kernel, these vendors often provide proprietary modules. Broadcom a package is often required bcmwl-kernel-source.
Installation can be done via the terminal, after updating the package lists. Command sudo apt update will update the repositories, and sudo apt install bcmwl-kernel-source will install the required module. After installation, the module needs to be activated, which usually happens automatically, but sometimes a command is required. modprobe wl.
With adapters Realtek The situation can be more complex, especially with newer models whose support isn't yet included in the stable kernel. In such cases, you may need to compile drivers from source code on GitHub, which is a more complex procedure requiring the installation of development packages (build-essential, linux-headers).
| Manufacturer | Typical driver package | Kernel module | Support status |
|---|---|---|---|
| Intel | iwlwifi (in the kernel) | iwlwifi | Excellent |
| Broadcom | bcmwl-kernel-source | wl | Good (proprietary) |
| Realtek | rtl88xxau-dkms (example) | 88XXau | Various (assembly is often required) |
| Atheros | ath9k (in the kernel) | ath9k | Excellent |
Troubleshooting common connection errors
Even with the drivers installed, connection errors may occur. One common issue is a power management conflict. The system may attempt to conserve power by disabling the Wi-Fi adapter, resulting in connection drops or failure to connect. This can be resolved by editing the configuration file.
Create or edit a configuration file /etc/NetworkManager/conf.d/default-wifi-powersave-on.confYou need to change the value in it. wifi.powersave on 2 (which means disabling power saving). After saving the file, restart the network service. This often resolves signal instability issues.
Another common error is an incorrect time and date in the system. If the computer's time is significantly different from the actual time, security certificates may be invalid, and connections to secure networks will be blocked. Make sure internet synchronization is enabled in the time settings.
- 🔋 Disable power saving for the Wi-Fi adapter in NetworkManager settings.
- 🕒 Check that your system time and date are correct.
- 🧹 Clear saved network profiles if your router's encryption type has changed.
- 🔌 Try changing the Wi-Fi channel on your router if you experience significant noise in the air.
⚠️ Note: Interfaces and package names may differ slightly between versions. Linux Mint (Cinnamon, MATE, Xfce) and depending on the kernel version. Always check the official documentation for your specific distribution version.
