How to check your laptop's Wi-Fi driver: from diagnostics to updating

Problems connecting to Wi-Fi on a laptop are often not related to the router or provider, but to network adapter driver. Failures manifest themselves in different ways: the Internet sometimes disappears, sometimes appears, the speed drops to 1 Mbps, or the laptop doesn't see available networks at all. In 80% of cases, an outdated, damaged, or incompatible driver is to blame—especially after a Windows update or system reinstallation.

This article will help Diagnose the status of the Wi-Fi driver on any laptop: from budget ones Acer Aspire before the games ASUS ROGWe will look at the methods of verification through device Manager, command line and third-party utilities, and we'll also learn how to distinguish hardware from software problems. All methods are relevant for Windows 10/11, Linux (Ubuntu/Debian) And macOS — taking into account the specific features of each OS.

If after checking it turns out that the driver is working correctly, but problems with Wi-Fi remain, proceed to our FAQ block, where we've compiled solutions for common scenarios (for example, when a laptop sees the network but doesn't connect).

1. Checking the Wi-Fi driver via Device Manager (Windows)

The fastest way to find out the driver status is to look in device Manager. All network adapters, their status, and software versions are displayed here. This guide is suitable for Windows 10 And Windows 11 (including the latest builds of 2026).

Open device Manager in one of the following ways:

  • 🔍 Click Win + X and select device Manager.
  • 🖱️ Right click on This computer → Properties → device Manager.
  • 🔎 Type in Windows search devmgmt.msc and press Enter.

In the window that opens:

  1. Expand the branch Network adapters.
  2. Find the device with the words Wireless, Wi-Fi, 802.11 or the model name (for example, Intel Wi-Fi 6 AX200, Qualcomm Atheros QCA61x4).
  3. Right click on it → Properties.

In the tab Driver Please note:

  • 📅 Date of development - if older than 2023, the driver is outdated.
  • 🔄 Driver version — compare with the latest on the manufacturer’s website.
  • ⚠️ Device status - If there is an exclamation mark, the driver is not working properly.

Driver date (is it up to date?)

Driver version (does it match the latest one on the manufacturer's website?)

No exclamation marks in status

Adapter name (does it match your laptop model?)-->

⚠️ Attention: If there is no device with Wi-Fi mentioned in the list of network adapters, it may mean that the adapter disabled in BIOS or physically damaged. Check the BIOS settings (section Advanced → Onboard Devices) or connect your laptop to the router via cable and update the drivers.

2. Command line: driver and network adapter diagnostics

Command line (CMD) allows you to obtain detailed information about the driver and Wi-Fi module status, including hidden errors. This method is useful if Device Manager doesn't show a problem, but the internet is unstable.

Open CMD as administrator (click Win + X → Terminal (Administrator)) and execute the commands one by one:

netsh wlan show drivers

This command will output:

  • 📋 Radio type (must be 802.11n/ac/ax — depending on the standard of your adapter).
  • 🔄 Hosted network support (If Yes, the adapter can distribute Wi-Fi).
  • ⚡ Radio status (should be On).
pnputil /enum-drivers | find "Wi-Fi"

Shows all installed Wi-Fi drivers with indication info file (needed for manual installation) and versions.

netsh interface show interface

Displays the status of all network interfaces. Look for the line with Wi-Fi and check:

  • 🔌 Admin State — it should be Enabled.
  • 📡 Media State - If Disconnected, the problem may be in the router or network settings.

3. Checking the driver via PowerShell (an alternative to CMD)

PowerShell provides more diagnostic capabilities than the standard command line. For example, here you can find out Equipment ID Wi-Fi adapter, which will be useful for finding the driver on the manufacturer's website.

Open PowerShell as administrator and run:

Get-NetAdapter | Where-Object {$_.Name -like "Wi-Fi"} | Select-Object Name, InterfaceDescription, Status, LinkSpeed

The command will output:

  • 🔖 Adapter name (For example, Wi-Fi 6).
  • 📄 Description (chip model, for example, Intel(R) Wi-Fi 6 AX201 160MHz).
  • 🔄 Status (Up - works, Down — disabled).
  • ⚡ Connection speed (For example, 866.7 Mbps).

To get Equipment ID (needed for manual driver search):

Get-PnpDevice | Where-Object {$_.Class -eq "Net"} | Select-Object FriendlyName, InstanceId

In the line InstanceId look for values ​​of the type PCI\VEN_8086&DEV_2723 - that's it Vendor ID And Device ID, which manufacturers use to identify devices.

How to decipher Vendor ID and Device ID?

Vendor ID (VEN) is a unique code of the chip manufacturer (for example, 8086 = Intel, 10EC = Realtek).

Device ID (DEV) — chip model (e.g. 2723 = Intel Wi-Fi 6 AX200).

This information will help you find the exact driver on the manufacturer's website if automatic installation does not work.

4. Checking the driver in Linux (Ubuntu/Debian)

IN Linux-In most systems, Wi-Fi drivers are managed through the kernel, but their status can be checked using standard utilities. If your laptop is on Ubuntu 22.04/24.04 or Debian does not see the network, follow these instructions.

Open Terminal (Ctrl + Alt + T) and run:

lspci -knn | grep -iA3 net

The command will list network devices. Look for the line with Network controller — this is your Wi-Fi adapter. Example output:

03:00.0 Network controller [0280]: Intel Corporation Wi-Fi 6 AX200 [8086:2723] (rev 1a)

Subsystem: Intel Corporation Wi-Fi 6 AX200NGW [8086:0024]


Kernel driver in use: iwlwifi


Kernel modules: iwlwifi

Please note:

  • 🔧 Kernel driver in use — the driver used (in the example — iwlwifi for Intel).
  • ⚠️ If instead of driver it says UNCLAIMED, then the driver is not installed.

To check the status of the Wi-Fi module:

iwconfig

Look for the interface with the name wlo1, wlan0 or something similar. If it's not there, the adapter is disabled or not recognized by the system.

To install/update the driver in Linux:

sudo apt update

sudo apt install firmware-iwlwifi # For Intel adapters


sudo modprobe -r iwlwifi && sudo modprobe iwlwifi # Reload the driver

⚠️ Attention: In some distributions (for example, Arch Linux) Wi-Fi drivers may require manual compilation from AURIf the adapter doesn't work after using the commands above, check the kernel logs: dmesg | grep iwlwifi.

5. Checking the driver on macOS (Apple Silicon and Intel)

On MacBook Wi-Fi drivers are built into the system, but their status can be diagnosed through System information And TerminalIf your Mac suddenly stops seeing networks or your speed has dropped, follow these steps.

Method 1: Through System information

  1. Click  → About This Mac → System Report.
  2. Go to the section Network → Wi-Fi.
  3. Check the fields:
    • 📡 Interface (For example, en0).
    • 🔧 Standards support (must be 802.11a/b/g/n/ac/ax).
    • ⚡ State (Connected or Disabled).

Method 2: Through Terminal

networksetup -listallhardwareports

Look for the block Wi-Fi or AirPort. Example output:

Hardware Port: Wi-Fi

Device: en0


Ethernet Address: a8:20:66:xx:xx:xx


...


Supports AirDrop: Yes


...

If the status says Hardware Port: Wi-Fi, Device: en0 (not attached), this means that the adapter disabled by hardware (maybe there is a problem with the antenna or cable).

To reset Wi-Fi settings on macOS:

sudo ifconfig en0 down

sudo ifconfig en0 up


sudo networksetup -setairportpower en0 on

Windows (Lenovo/HP/Asus, etc.)

MacBook (Apple)

Linux (Ubuntu/Debian/Fedora)
