Why Wi-Fi isn't working on Windows 10: A complete troubleshooting and repair guide

You turned on your laptop or PC with Windows 10Have you connected to your home Wi-Fi network, but the internet stubbornly doesn't work—pages won't load, instant messaging apps are offline, and a yellow triangle with an exclamation point is flashing in the system tray? This problem is familiar to millions of users, and there can be dozens of causes, from a simple driver glitch to hidden router settings you never even knew existed.

Unlike a wired connection, where problems often come down to the cable or port, wireless network depends on a whole range of factors: compatibility of standards (Wi-Fi 5 vs Wi-Fi 6), encryption (WPA3 vs WPA2), frequency ranges (2.4 GHz or 5 GHz), as well as internal conflicts of the Windows 10. For example, after the next system update (KB5034441 (as of January 2026) many users have experienced a massive failure of Wi-Fi adapters Intel AX200 - and this is not an isolated case.

In this article we will look at All possible reasons for the lack of Wi-Fi internet on Windows 10, from basic checks to in-depth diagnostics of network protocols. You'll learn how to distinguish a PC-related issue from a faulty router, and why a simple reboot sometimes helps, while a manual registry edit is sometimes required. And yes, we won't recommend "reinstalling Windows" or "buying a new adapter" without a good reason.

1. Check the obvious: router, adapter, and basic settings

Before digging deep into system settings, make sure the problem isn't just on the surface. Statistics show Netgear And TP-Link, in 35% of cases, "non-working Wi-Fi" is actually related to external factors, not the PC.

Start with the simplest:

• 🔌 Reboot your routerUnplug the power cord for 30 seconds - this will reset the DHCP cache and temporary locks. This is especially important for models ASUS RT-AX88U And Keenetic Ultra, where the firmware sometimes "freezes" after a long period of operation.
• 📶 Check the indicators on the router. Burning Wi-Fi (usually green or blue) indicates the wireless network is active. If it's blinking orange, the network is disconnected or experiencing a network failure.
• 💻 Make sure Wi-Fi is enabled on your PC.On laptops Lenovo And HP the hardware key lock is often triggered Fn + F2 or Fn + F12On desktop PCs, check if the adapter is disabled in Device Manager.
• 🔄 Connect to another networkTry connecting to Wi-Fi from your phone or a neighbor's network (with permission!). If the internet works, the problem is with your router or its settings.

If the internet still doesn't work after these steps, proceed to the next step. But first, answer this question:

Important! On some routers (for example, Zyxel Keenetic) after updating the firmware the settings may be reset IPv6, which results in a lack of internet access on Windows 10. More on this in the section on network protocols.

2. Diagnosing the network adapter in Windows 10

If the router is working, but Windows 10 stubbornly refuses to connect to the internet via Wi-Fi, the problem most likely lies with the network adapter. This could be:

• 🚫 Disabled adapter (software or hardware).
• 🔧 Outdated or corrupted driver.
• ⚡ Conflict with other devices (for example, with a Bluetooth adapter).
• 🛠️ Windows services crash (WLAN AutoConfig).

First, check the adapter status:

1. Click Win + X and select device Manager.
2. Expand the tab Network adapters.
3. Find your Wi-Fi adapter (e.g. Qualcomm Atheros QCA61x4 or Intel Wi-Fi 6 AX200).
4. If there is an arrow ⬇️ next to the name, right-click and select Activate the device.

If the adapter is enabled but the Internet still doesn't work, update the driver:

Right-click on the adapter → Update driver

Select "Automatic Search"

If Windows did not find any updates, download the driver from the manufacturer's website (for example, [support.lenovo.com](https://support.lenovo.com))

Install the driver manually via "Browse my computer for driver software" -->

Warning: Do not use drivers from third-party sites (like driverpack.io) - they often contain malware. Download only from official resources. Intel, Qualcomm, Realtek or the laptop manufacturer.

What should I do if Windows says "The best drivers are already installed" but Wi-Fi isn't working?

This means the system doesn't see a newer driver version in its repository. In this case:

1. Uninstall the current driver (right-click → Uninstall device).

2. Restart your PC - Windows will install the basic driver automatically.

3. If this does not help, download the driver from the manufacturer's website and install it manually, selecting the "Install this software anyway" option (if a compatibility warning appears).

3. Reset network settings and Windows services

Often the problem lies not in the adapter, but in the wrong settings. TCP/IP or disabled services. Windows 10 is known to arbitrarily change network settings after updates, especially if you use a VPN or proxy.

First, reset your network settings:

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

If this does not help, check the status of key services:

1. Click Win + R, enter services.msc and press Enter.
2. Find services:
   • WLAN Automatic Configuration Service (should be In progress).
   • Network connections (startup type - Automatically).
   • DHCP client (if disabled, Wi-Fi will connect, but without the Internet).

If the service is disabled, right-click and select Launch.

Attention ⚠️ After resetting the network, all saved Wi-Fi passwords will be deleted. Prepare a list of them in advance or test them on another device.

4. IP address conflicts and DHCP settings

One of the most insidious reasons for the lack of internet via Wi-Fi is IP address conflictThis happens when the router assigns your PC an address that is already taken by another device on the network (for example, a printer or IP camera). As a result, Windows 10 connects to Wi-Fi, but the internet doesn't work, and Network and Control Center you see the status "No network access".

Check your current settings:

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Click on your Wi-Fi connection → Intelligence.
3. Look at the line IPv4 addressIf it starts with 169.254.x.x - this means that DHCP failed and Windows assigned itself a backup address.

To fix this, do the following:

1. Open Settings → Network & Internet → Wi-Fi → Manage known networks.
2. Select your network → Properties.
3. Scroll to IP settings and select Manually.
4. Turn on IPv4 and enter:
   • IP address: 192.168.1.100 (or another free one in your subnet).
   • Subnet mask: 255.255.255.0.
   • Gateway: 192.168.1.1 (usually matches the router IP).
   • DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

Save and reconnect to the network.

Attention ⚠️ If after manual IP configuration the internet works, but after some time it disappears again, check the router for the function IP-MAC Binding (IP-to-MAC address binding). It can block your PC if its MAC address is not whitelisted.

5. Problems with IPv6 and security protocols (WPA3, 802.11r)

Modern routers support new security standards and protocols that don't always work correctly with Windows 10. For example:

• 🔒 WPA3This encryption protocol may cause connection issues on adapters older than 2019 (e.g. Intel 8265 or Broadcom 4352).
• 🌐 IPv6If your router is configured to prioritize IPv6 and your ISP doesn't support it, Windows 10 may freeze when attempting to obtain an address.
• ⚡ 802.11r (Fast Roaming)Fast Reconnection technology between access points may conflict with Windows drivers.

To check these settings:

1. Open Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings.
2. Right-click on your Wi-Fi connection → Properties.
3. Uncheck the box Internet Protocol version 6 (TCP/IPv6) and restart your PC.

If the problem is WPA3:

1. Go to your router settings (usually at 192.168.1.1 or 192.168.0.1).
2. Find the section Wireless → Security.
3. Change it WPA3 on WPA2-PSK (or WPA2/WPA3 Mixed).
4. Save settings and reconnect.

Attention ⚠️ On some routers (ASUS RT-AX86U, Netgear Nighthawk) After disabling IPv6, you may lose access to local resources (such as network drives or printers). In this case, re-enable IPv6 and manually configure DNS. 8.8.8.8 in IPv4 settings.

6. Hidden Windows 10 Settings: Power Saving and Network Policies

Windows 10 aggressively optimizes power consumption, which sometimes leads to the Wi-Fi adapter being disabled in the background. The system also has hidden policies that can block connections to certain types of networks.

Check your power saving settings:

1. Open device Manager → Network adapters.
2. Right-click on your 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.

If this doesn't help, check network policies:

1. Click Win + R, enter gpedit.msc (if you have Windows 10 Pro) or regedit (For Home).
2. Follow the path:

   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Network Connectivity Status Indicator

3. If there is a parameter NoActiveProbe, set its value to 0.

Helpful tip:

7. Viruses, VPNs, and third-party programs

Many users overlook that antiviruses, VPN clients and even download managers may block the network connection. For example:

• 🛡️ Kaspersky Internet Security And ESET NOD32 Sometimes DNS requests are blocked if the "Network Protection" module is enabled.
• 🌍 NordVPN, ProtonVPN and Windows' built-in VPN can "substitute" routes, causing the Internet to disappear after disconnection.
• 📥 uTorrent, qBittorrent and other torrent clients sometimes mess up the settings MTU (maximum packet size), which leads to connection breaks.

To check the impact of third-party programs:

1. Boot Windows into Safe Mode with Networking (click Win + R, enter msconfig, go to the tab Loading and select Safe Mode → Network).
2. If Wi-Fi works in safe mode, the problem is in one of the installed programs.
3. Return to normal mode and disable antiviruses, VPNs, and torrent clients one by one, checking the connection.

Attention ⚠️ Some antiviruses (for example, Avast) establish their own DNS proxy, which may conflict with your router settings. If the internet works after removing the antivirus, install a different one (for example, Bitdefender or built-in Windows Defender).

8. Hardware faults: how to check the adapter and antennas

If you've tried all the software methods and Wi-Fi still isn't working on Windows 10, the problem might be hardware:

• 📡 Damaged Wi-Fi adapter (especially relevant for laptops after falls).
• 🔌 Detached antennas (in laptops they are connected to the adapter with thin wires that can come loose due to vibration).
• ⚡ Chip overheating (on some models Realtek RTL8821CE The adapter switches off at temperatures above 70°C).

How to check hardware health:

1. Connect an external Wi-Fi adapter (For example, TP-Link TL-WN725N). If the Internet works with it, the problem is in the internal adapter.
2. Check the antennas (relevant for PCs and some laptops):
   • Open the back cover of the laptop (or PC case).
   • Find your Wi-Fi adapter (usually a small board with two antenna wires).
   • Carefully disconnect and reconnect the antennas (they are marked MAIN And AUX).

Check the temperature by using HWMonitor or AIDA64If the adapter heats up above 70°C, additional cooling is required.

Attention ⚠️ If you're unsure of your disassembly skills, it's best to take your device to a service center. Damage to the antennas or adapter during DIY repairs could result in a complete loss of Wi-Fi.

FAQ: Frequently Asked Questions about Wi-Fi on Windows 10

Why does Wi-Fi work on my phone but not on Windows 10?

This is a sign of a problem on the PC side. Possible causes:

• The Wi-Fi adapter driver is outdated or corrupted.
• It's enabled in the router settings. WPA3, which is not supported by your adapter.
• Service WLAN AutoConfig disabled.
• IP conflict (your PC is assigned an address that is already in use by another device).

Start with driver updates And IP checks.

My Wi-Fi stopped working after updating Windows 10. What should I do?

Windows updates often disrupt network adapter drivers. Try:

1. Roll back driver: in Device Manager click on the adapter → Properties → Driver → Roll Back Driver.
2. Remove last update: Settings → Update & Security → View update history → Uninstall updates.
3. Install the driver from the manufacturer's website (not via Windows Update!).

If the problem appeared after KB5034441 (January 2026), check the website for a special patch for your adapter Microsoft.

The Wi-Fi connects, but the pages won't load. What's wrong?

This is usually associated with:

• DNS: try to write it manually 8.8.8.8 or 1.1.1.1.
• Proxy: check if proxy is enabled in Settings → Network & Internet → Proxy.
• Firewall: Please disable it temporarily and check the connection.
• MTU: If pages load partially or slow down, try changing MTU at 1400 (via command netsh interface ipv4 set subinterface "Connection_Name" mtu=1400 store=persistent).

How do I know what Wi-Fi adapter I have?

There are several ways:

1. Through device Manager: Network adapters → the name of your adapter (for example, Intel(R) Wi-Fi 6 AX200).
2. Via command: open Command line and enter:

   wmic nic get name, manufacturer

3. Through AIDA64 or Speccy (in the section Net).

Can I use a USB Wi-Fi adapter if the built-in one is broken?

Yes, this is the simplest solution. Recommended models:

• TP-Link TL-WN725N (budget, Wi-Fi 4, up to 150 Mbit/s).
• ASUS USB-AX56 (Wi-Fi 6, up to 1800 Mbps, support WPA3).
• D-Link DWA-192 (external antenna, good signal).

Connect the adapter, install the driver from the official website, and Wi-Fi will work as if on a new PC.
