My laptop isn't detecting Wi-Fi in Windows 10: Step-by-step instructions for restoring the connection

You turned on your laptop, but the list of available networks is empty. Or instead of the usual Wi-Fi The message "No connections available" is flashing. This situation is familiar to many: The laptop stopped detecting Wi-Fi. for no apparent reason, even though other devices (smartphone, tablet) connect to the network without issue. In 90% of cases, the problem is resolved independently, without contacting a service center.

In this article we will look at all the possible reasons why Windows 10 doesn't detect Wi-Fi, from the mundane (a disconnected adapter) to the complex (hardware problems). Each method is illustrated with screenshots and step-by-step instructions. If you're not a technical expert, start with the first steps and proceed to the next ones until the network is working.

Important: Some solutions require administrator privileges. If you are using a work laptop with limited privileges, please contact your company's IT department.

1. Check physical switches and keyboard shortcuts

The first thing to do is to make sure that The Wi-Fi adapter is turned on at the hardware level. Many laptops (especially models HP, Lenovo, Dell) have:

• 🔄 Hardware switch on the body (usually on the side or front) with an antenna icon.
• 🔑 Keyboard shortcut to turn on/off wireless modules (for example, Fn + F2, Fn + F12 — depends on the model).
• ⚡ Wi-Fi indicator on the panel (lights up blue/orange if the adapter is active).

On laptops ASUS And Acer a combination is often used Fn + F2, on Lenovo — Fn + F5 or Fn + F7If you're not sure, look at the icons on the keys. F1–F12: the one you need will have an image of an antenna or an airplane (airplane mode).

If the switch is in the "On" position and the indicator light is not on, try:

1. Turn off the laptop (do not restart, but turn it off completely).
2. Remove the battery (if removable) for 30 seconds.
3. Turn on the laptop again and check the Wi-Fi indicator.

2. Restart your router and laptop

It's trivial, but it works in 30% of cases: The problem may be on the router's side, not the laptop. For example, the router froze after a firmware update or due to overheating. To rule this out:

• ⚡ Unplug the router for 1-2 minutes (don't just press the power button, but unplug it from the outlet).
• 🔄 Wait 30 seconds and turn it back on.
• 💻 Restart your laptop (Start → Shutdown → Restart).

After reboot, check:

• Is the Wi-Fi indicator on the router lit (should it be blinking or constantly lit?)
• Does the network see at least one other device (smartphone, tablet)?
• Has a notification about available networks appeared in Windows (the icon in the lower right corner of the screen).

If other devices connect to the router but your laptop doesn't, proceed to the next step.

3. Check the status of your Wi-Fi adapter in Device Manager

Windows 10 may disable your Wi-Fi adapter due to driver conflicts, power saving issues, or system errors. To check its status:

1. Click Win + X and select device Manager.
2. Expand the section Network adapters.
3. Find the device with the names Wireless, Wi-Fi, 802.11 or adapter model (for example, Intel Wi-Fi 6 AX200, Qualcomm Atheros QCA61x4).

Please note the icons next to the adapter name:

• ⚠️ Yellow triangle with an exclamation mark — the driver is not working properly or is damaged.
• ↓ Down arrow — the adapter is disabled.
• 🔴 Red cross — the device is disabled at the system level.

If the adapter is disabled:

1. Right click on it → Engage.
2. If the option is not available, select Turn on the device.

What if the adapter is not on the list?

If there is no device listed as Wi-Fi in the Network Adapters section, this may mean:

- The adapter is disabled in BIOS/UEFI.

- The driver is completely removed or not installed.

- Hardware failure (for example, the antenna inside the laptop has become disconnected).

If the yellow icon next to the adapter is lit:

1. Right click → Properties.
2. Tab General → look at the error code (for example, Code 10, Code 43).
3. Go to the tab Driver → click Roll back (if the button is active) or Update driver.

4. Update or reinstall your Wi-Fi driver

Outdated or corrupted drivers are one of the most common reasons why The laptop doesn't see Wi-Fi.In Windows 10, drivers can be updated automatically, but this sometimes leads to conflicts. Let's look at two solutions:

Method 1: Automatic update via Device Manager

1. Open device Manager (Win + X → Device Manager).
2. Expand Network adapters, right-click on the Wi-Fi adapter → Update driver.
3. Select Automatic search for updated drivers.

If Windows reports that the drivers are up to date, but the problem persists, proceed to manual installation.

Method 2: Manual installation from the manufacturer's website

Automatic updates don't always find the most stable version. It's best to download the driver from the official website:

1. Determine the model of your Wi-Fi adapter (in Device Manager or through the command ipconfig /all V Command line).
2. Go to the manufacturer's website:
   • Intel: intel.ru (Support section)
   • Qualcomm Atheros: qualcomm.com
   • Realtek: realtek.com
   • Broadcom: Drivers are usually available on the laptop manufacturer's website.

Download the driver for your model and Windows version (x64 or x86).

Remove the old driver via device Manager (right click → Remove device, check the box "Delete the driver software for this device").

Install the downloaded driver and restart your laptop.

- Does the laptop see the list of networks?

- Is the connection stable (no constant interruptions)?

- Does the Internet speed correspond to the tariff?

- Are there any errors next to the adapter in Device Manager?-->

If Wi-Fi still doesn't appear after updating the driver, try roll back the driver to the previous version (tab Driver → Roll back).

5. Check your power settings

Windows 10 optimizes power consumption by default, and sometimes this leads to automatic shutdown of the Wi-Fi adapter to save battery power. To disable this feature:

1. Open device Manager (Win + X).
2. Expand Network adapters, right-click on the Wi-Fi adapter → Properties.
3. Go to the tab Power management.
4. Uncheck the box Allow the computer to turn off this device to save power.
5. Click OK and restart your laptop.

Also check the power supply diagram:

1. Open Control Panel (Win + R → enter control → Enter).
2. Go to Equipment and Sound → Power Supply.
3. Opposite the active scheme, click Setting up a power plan.
4. Select Change advanced power settings.
5. Find the section Wireless Network Adapter Settings → Power saving mode.
6. Set value Maximum performance for both states (battery and mains).

6. Reset network settings and check the WLAN autoconfiguration service

If the previous methods did not help, the problem may be in system network settings or a disabled service. Let's start by resetting network settings:

1. Open Windows Settings (Win + I).
2. Go to Network and Internet → Status.
3. Scroll down and click Network reset.
4. Confirm the action and restart the laptop.

After the reset, all saved networks will be deleted and will have to be reconnected.

If resetting doesn't help, check the service status Automatic WLAN configuration:

1. Click Win + R, enter services.msc → Enter.
2. Find a service Automatic WLAN configuration (or WLAN AutoConfig).
3. Double click on it, install Launch type → Automatically.
4. Click Launch (if the service is stopped) → OK.

Also make sure the service is enabled Network connections (Network Connections) And Network placement (Network Location Awareness).

7. Diagnostics of hardware faults

If none of the software methods worked, the problem may be in hardware:

• 📡 The Wi-Fi module is damaged (for example, after a laptop falls).
• 🔌 The antennas have come loose from the adapter (a common problem after disassembling a laptop).
• 🔥 The controller burned out due to a power surge.

To check this:

1. Connect an external Wi-Fi adapter (For example, TP-Link TL-WN725N) via USB. If it works, the problem is in the internal module.
2. Check it out, Does the laptop see other networks? (for example, from a phone in hotspot mode). If not, the adapter is faulty.
3. Open BIOS/UEFI (when loading, press F2, Del or Esc) and check if the Wi-Fi adapter is enabled in the settings (Advanced → Wireless LAN).

If the adapter isn't detected even in the BIOS, it will need to be replaced. This will cost around 1,500–4,000 rubles (depending on the laptop model and module type).

If you're unsure of your abilities, it's best to contact a service center. Doing repairs yourself could void the warranty (if the laptop is new) or damage other components.
