My laptop can't see Wi-Fi, but my phone can connect. What should I do?

Is your laptop not showing your home Wi-Fi network in the list of available connections, even though your phone or tablet can easily find the router and connect to the internet? This could be due to hardware issues (disabled adapter, corrupted driver) or network settings (hidden SSID, incompatible Wi-Fi 6/6E standard on newer router models). Before reinstalling Windows or calling a technician, check if the Wi-Fi power button on the laptop works, if the adapter is visible in Device Manager, and if your antivirus or VPN is blocking the connection.

The problem may lie in the laptop's settings (outdated drivers, disabled adapter, software conflicts) or in the router's settings (hidden network name, incompatible Wi-Fi standard, MAC address restrictions). In this article, we'll look into these issues. all possible reasons and we will give step-by-step instructions for Windows 10/11 And macOSYou'll also learn how to check if your antivirus is blocking your connection and what to do if the problem appears after a system update.

Don't rush to reset your router or reinstall Windows—in 90% of cases, the solution is much simpler. Start with our troubleshooting guide, and you'll save hours!

1. Check the physical condition of the Wi-Fi adapter on your laptop

The first thing to do is to make sure that The laptop's Wi-Fi module is turned on. and works correctly. Often, the problem lies in trivial things: a disabled button on the case, a slider in the BIOS, or mechanical damage to the antenna.

Most laptops have one hardware button or a key combination to turn Wi-Fi on/off. For example, on devices Lenovo this is often Fn + F5 or Fn + F7, on HP — Fn + F12, and on ASUS There may be a separate switch on the side panel. Check if the Wi-Fi indicator is red or orange—this indicates the module is blocked.

• 🔍 Keyboard shortcuts: Find on the keys F1-F12 antenna or airplane icon (airplane mode). Click Fn + [corresponding key].
• 💻 BIOS/UEFI: On some laptops (especially Dell or Acer) Wi-Fi may be disabled in the BIOS settings. Go to the BIOS (usually F2, Del or Esc when booting) and check the section Advanced → Wireless.
• 🔌 Mechanical damage: If the laptop was dropped or disassembled, the Wi-Fi module antennas may have become detached. In this case, diagnostics at a service center are required.

⚠️ Attention: If both Wi-Fi and Bluetooth stop working after a laptop is dropped, the wireless module is almost certainly loose or damaged. Unexperienced DIY repairs can lead to permanent damage.

2. Update or reinstall your Wi-Fi adapter driver

One of the most common reasons why The laptop doesn't see Wi-Fi. — outdated, damaged, or incompatible drivers. This is especially true after a Windows update or system reset. A driver may simply crash or conflict with the new OS version.

To check and update the driver:

1. Click Win + X and select device Manager.
2. Expand the tab Network adapters.
3. Find the device with the names Wireless, Wi-Fi, 802.11 or chip model (for example, Intel AX200, Qualcomm Atheros, Realtek RTL8821CE).
4. Right click and select Update driver → Automatic search.

If the automatic update does not help, download the driver manually from the laptop manufacturer's website (section Support or Downloads). Please specify the exact laptop model and Windows version! For macOS Drivers are updated through Software update in the system settings.

⚠️ Attention: If in Device Manager There is an exclamation mark next to the adapter name or it is displayed as Unknown device This is a sign of a critical driver error. In this case, the only solution is a complete reinstallation from the official website.

3. Check your router settings: Wi-Fi standard and channels

If your phone sees Wi-Fi but your laptop doesn't, the problem may be incompatibility of wireless network standardsModern routers support standards 802.11a/b/g/n/ac/ax (Wi-Fi 4/5/6), but older laptops (especially before 2015) may not work with new modes, for example, Wi-Fi 6 (802.11ax).

Conflicts also arise due to:

• 📡 Wrong channel: If the router is configured to channel 12-14 (allowed in Japan, but banned in Russia/EU), some devices won't see it.
• 🔒 Hidden network (SSID): If the network name display is disabled in the router settings (Hide SSID), the laptop will not be able to detect it without manual input.
• 🔄 5 GHz mode: Old laptops only support 2.4 GHzCheck if this range is disabled in your router.

To change router settings:

1. Connect to the router via cable or phone (if you have access to the web interface).
2. Enter the router's address in the browser (usually 192.168.0.1, 192.168.1.1 or tplinkwifi.net).
3. Go to the section Wireless or Wi-Fi and check:
   • Network standard (Mode): put 802.11n/ac (for compatibility).
   • Channel (Channel): select 1-11 for 2.4 GHz.
   • SSID Visibility: Enable Enable SSID Broadcast.

⚠️ Attention: Router settings may reset after a firmware update. If you recently updated your router's firmware, check your settings again—they may have reverted to factory defaults.

How do I know which Wi-Fi standard my laptop supports?

Open device Manager, find your Wi-Fi adapter and check its model. Enter the name in a search engine—the specifications will indicate the supported standard (e.g., Intel AX200 works with Wi-Fi 6).

4. Disable power saving for your Wi-Fi adapter

Windows 10/11 By default, this feature enables power saving mode for wireless adapters, which can cause them to disconnect or become unstable. This is especially true for laptops running on battery power. To disable this feature:

1. Open device Manager (Win + X).
2. Find your Wi-Fi adapter in the section Network adapters.
3. Right click → Properties → tab Power management.
4. Uncheck the box Allow the computer to turn off this device to save power.

For macOS a similar setting is in System Preferences → Battery → Power Saver. Make sure the option is Dim the display slightly when running on battery power does not affect network connections (sometimes Apple blocks background processes to save battery).

Also check power plan in Windows:

• 🔋 Go to Control Panel → Power Options.
• Choose a plan High performance.
• Click Set up a power plan → Change advanced settings.
• Find Wireless Network Adapter Settings → Power Saving Mode and put Maximum performance.

5. Check for conflicts with your antivirus, VPN, or firewall

Security software (antiviruses, firewalls, VPN clients) can block Wi-Fi connections, especially if the network appears "suspicious." Conflicts most often arise with:

• 🛡️ Kaspersky Internet Security (module Firewall).
• 🔒 Avast/AVG (function Wi-Fi Inspector).
• 🌍 NordVPN, ProtonVPN (can redirect traffic).
• 🖥️ Built-in Windows Firewall (sometimes blocks new networks).

To check if the software is to blame:

1. Temporarily disable your antivirus (right-click on the tray icon → Suspend protection).
2. Disable VPN (if using).
3. Check if the network appears in the list of available ones.
4. If yes, add your network to the antivirus exceptions or configure firewall rules.

For Windows Firewall:

1. Open Control Panel → Windows Firewall.
2. Select Allow interaction with an application or component.
3. Make sure there are check marks next to your network Network discovery And File and Printer Sharing.

⚠️ Attention: If Wi-Fi works again after disabling your antivirus, don't leave it disabled for too long! Add your network to trusted networks or update your antivirus databases—sometimes conflicts arise due to outdated signatures.

6. Reset your network or router settings

If none of the above helps, try reset network settings on your laptop or router. This will restore all settings to factory defaults and eliminate any possible software conflicts.

For Windows 10/11:

1. Open Settings → Network & Internet → Status.
2. Scroll down and click Network reset.
3. Confirm the action and restart the laptop.

For macOS:

1. Open Terminal (through Spotlight or Programs → Utilities).
2. Enter the command:

   sudo ifconfig en0 down && sudo ifconfig en0 up

   (replace en0 to your network interface, if it is different).

3. Restart your Mac.

For router:

• 🔄 Click the button Reset on the back panel of the router (hold for 10-15 seconds).
• 📝 After the reset, you will need to reconfigure your internet connection (the details from your provider are usually specified in your contract).
• ⚙️ Use standard Wi-Fi settings (e.g. Channel: Auto, Channel width: 20/40 MHz).

⚠️ Attention: Resetting your router will erase all user settings, including your Wi-Fi password, guest network, and parental controls. Be sure to back up important settings or take photos of the configuration pages beforehand.

How can I find my internet connection details after resetting my router?

Usually the login and password for connecting to the provider are indicated in the contract or on a sticker on the router itself (field PPPoE or Internet). If not, call your provider's support team and ask them to re-pronounce the settings.

7. Diagnosing hardware problems

If the laptop doesn't see not a single one Wi-Fi network (including public ones), and all software methods have been tried - the problem is most likely hardwareHere's what could have gone wrong:

• 📶 Wi-Fi module: The contacts have burned out or come loose (often after overheating or falling).
• 🔌 Antennas: Damaged or disconnected from the module.
• 🔋 Module power supply: There is a fault on the motherboard (for example, a burnt-out capacitor).

To check:

1. Connect to laptop external USB Wi-Fi adapter (costs from 500 ₽). If it works, the problem is in the internal module.
2. Check if the Wi-Fi adapter is detected in Device ManagerIf it's not there at all, the module is faulty or disabled at the BIOS level.
3. See if it works Bluetooth (It's often built into the same module.) If it doesn't work either, it's almost certainly a hardware issue.

If your laptop stops detecting Wi-Fi after liquid spills, impact, or severe overheating, do not attempt to repair it yourself. Corrosion of the contacts or microcracks on the circuit board can lead to complete failure of the device.

FAQ: Frequently Asked Questions

My laptop can't connect to Wi-Fi after a Windows update. What should I do?
