No Internet on Windows 10 PC but Wi-Fi Works: Complete Troubleshooting Guide

You've turned on your laptop or system unit and connected to your home Wi-Fi network, but your browser keeps showing the "No Internet Connection" error, while everything works fine on your smartphone or tablet? This situation is familiar to many users. Windows 10The causes may lie in both software glitches in the operating system and hardware problems, ranging from outdated drivers to incorrect router settings.

In this article we will look at All possible reasons why there is no internet on a PC even though Wi-Fi is workingWe'll also provide step-by-step troubleshooting instructions. You'll learn how to diagnose the problem, which settings to check first, and when to contact a specialist. We'll pay special attention to cases where other devices (phones, smart TVs) are connected to the same network and work without problems—this narrows down the possible culprits.

Important: If you have Windows 11, most of the methods in this article are also applicable, but the paths to some settings may differ. For owners of desktop PCs with a cable connection Ethernet Some of the recommendations are also relevant - the principles of diagnosing network problems are universal.

1. Checking basic parameters: router, cables and indicators

Before diving into the settings Windows 10, make sure the problem isn't physical. Start by inspecting the hardware:

  • 🔌 Router power supply: Check if the power indicator on your router is lit. If it's blinking or missing, try rebooting the device (unplug it for 30 seconds).
  • 📡 Wi-Fi indicator: The wireless network LED on the router should be lit or blinking. If it's off, Wi-Fi sharing may be disabled.
  • 🖥️ PC network card: On laptops there is usually a physical switch or key combination (eg. Fn + F2) to turn Wi-Fi on/off. Make sure the adapter is activated.
  • 🔗 Cable connections: If you have a hybrid network (Wi-Fi + wired connection), check that the cable is securely inserted. Ethernet into the PC and router port.

If the router's lights are unusual (for example, red or rapidly blinking), this may indicate a hardware problem. In this case, try connecting an internet cable directly to your computer, bypassing the router. If the internet works, the problem is with the router.

⚠️ Attention: On some router models (for example, TP-Link Archer C6 or ASUS RT-AX58U) The Wi-Fi indicator may behave abnormally when the power saving feature is enabled. Check the settings in the router's web interface.

2. Diagnosing the network adapter in Windows 10

If everything is fine at the physical level, we move on to software diagnostics. Windows 10 has built-in tools for checking network connections:

  1. Click Win + X and select "Network Connections"** (or open Settings → Network & Internet).
  2. Check your connection status: if there is an inscription next to the name of your network "Connected, no internet access"** - problem confirmed.
  3. Right click on the network and select "Troubleshooting"** - the system will automatically scan and attempt to fix errors.

If automatic diagnostics did not help, open "Device Manager"** (Win + X → Device Manager) and check the status of the network adapter:

  • 🔍 Expand the tab Network adapters**.
  • 🚫 If there is a Wi-Fi adapter near your Wi-Fi adapter (for example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA9377) there is a yellow exclamation mark - the driver is not working properly.
  • ↻ Try updating the driver (right click → "Update driver"**).

For a more in-depth diagnosis, open command line as administrator (Win + X → Command Prompt (Administrator)) and run the commands:

ipconfig /all

ping 8.8.8.8


ping ya.ru

If ping 8.8.8.8 it goes well (there are answers), but ping ya.ru - No, the problem is most likely in the settings. DNS.

Make sure Wi-Fi is enabled on your PC|Check the connection status in Network Settings|Run automatic diagnostics|View network adapters in Device Manager|Run ping commands in CMD-->

3. Reset network settings and TCP/IP parameters

A common reason for the lack of internet connection when Wi-Fi is working is incorrect network settings. Windows 10 There are several ways to reset them:

Method 1: Reset via Settings

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

Method 2: Manual reset via command line

Open CMD as administrator and execute the commands sequentially:

netsh winsock reset

netsh int ip reset


ipconfig /release


ipconfig /renew


ipconfig /flushdns

After executing each command, wait for a message confirming the reset was successful. Then restart your PC.

⚠️ Attention: Resetting your network will delete all saved Wi-Fi passwords. Make sure you have them ready or have access to your router to reconnect.
Team What does it do? When it helps
netsh winsock reset Resets the Winsock catalog If problems are caused by corrupted network libraries
netsh int ip reset Restores TCP/IP parameters For errors like "IP configuration is invalid"
ipconfig /flushdns Clears the DNS cache If websites don't open, but ping works

4. Checking and updating network adapter drivers

Outdated or corrupted drivers are one of the most common reasons for a lack of internet connection. Even if There is no exclamation mark in the Device Manager**, this does not guarantee that the adapter is working correctly.

How to update the driver manually:

  1. Open device Manager (Win + X).
  2. Expand "Network adapters"** and find your Wi-Fi module (for example, Realtek RTL8821CE or Broadcom 802.11ac).
  3. Right click → “Update driver” → “Automatic search”**.

If Windows If the driver is up-to-date, but the problem persists, download it manually from the adapter or laptop manufacturer's website. For example:

  • 💻 For laptops Lenovo: [support.lenovo.com](https://support.lenovo.com)
  • 🖥️ For adapters Intel: [downloadcenter.intel.com](https://downloadcenter.intel.com)
  • 🌐 For Realtek: [realtek.com](https://www.realtek.com)
⚠️ Attention: After installing the new driver, you may need to reboot. If Wi-Fi disappears completely after the update, roll back the driver using “Properties → Roll Back Device”** in “Device Manager”.

5. Configure DNS and check IP settings

Incorrect settings DNS or IP Internet access may be blocked even if Wi-Fi is connected. This often occurs after changing the router configuration or installing a VPN.

How to check current settings:

  1. Open Control Panel → Network and Internet → Network and Sharing Center.
  2. Click on the Wi-Fi connection → "Intelligence"**.
  3. Check the fields IPv4 Address And DNS servers.

If the address starts with 169.254.x.x This means the PC hasn't received the correct IP address from the router. This can be fixed as follows:

Manual IP and DNS configuration:

  1. In the same window, click “Properties” → “Internet Protocol Version 4 (TCP/IPv4)” → “Properties”**.
  2. Select "Use the following IP address"** and enter:
    • IP address: 192.168.1.X (where X is a number from 2 to 254, not occupied by other devices)
    • Subnet mask: 255.255.255.0
    • Default gateway: 192.168.1.1 (or another address of your router)
  • In the field "DNS servers"** please specify 8.8.8.8 (Google) and 1.1.1.1 (Cloudflare).

    • If after these manipulations the Internet does not work, return the settings to the mode “Obtain an IP automatically”** – the problem may be with the router itself.

    What should I do if my router distributes IP addresses from the 169.254.xx range?

    This means the DHCP server on your router is down or blocked. Try:

    1. Reboot the router.

    2. Temporarily disable the firewall/antivirus on your PC.

    3. Check if the router is set to “AP” (access point) mode instead of “Router”.

    4. Reset the router to factory settings (press and hold the Reset button for 10 seconds).

    6. Check your firewall, antivirus, and third-party programs

    Sometimes internet access is blocked by security programs or incorrect settings. Windows FirewallStart by temporarily disabling protection:

    • 🛡️ Windows Firewall:
      1. Open Control Panel → Windows Firewall.
      2. Select "Turning the firewall on and off"**.
      3. Mark "Disable firewall"** for private and public networks.
  • 🦠 Antivirus: Temporarily disable real-time protection (for example, in Kaspersky, ESET NOD32 or Avast).
  • 🔄 VPN clients: if you have programs like OpenVPN or NordVPN, delete them or reset the settings.

    • If the internet works after disabling protection, the problem is in your security settings. Add an exception for your network or reinstall the antivirus.

    Also check the list of installed programs (Settings → Applications): sometimes the culprit is utilities for “optimizing” the network (for example, Driver Booster or CCleaner), which break network settings.

    7. Hardware problems: what to do if nothing helps

    If all software methods have been tried, but there is still no internet connection on your PC, there may be a hardware problem:

    • 📶 Wi-Fi adapter malfunction: try connecting your PC to the router via cable EthernetIf the internet works, the problem is with the wireless module. For laptops, the solution is USB Wi-Fi adapter (costs from 500 ₽).
    • 🔌 Problems with the port or cable: If you are using a wired connection, check the cable on another device or replace it.
    • 🔄 Incompatibility of standards: if the router is operating in mode 802.11ac (5 GHz), and the PC adapter only supports 802.11n (2.4 GHz), the connection will be unstable. Check your router settings.

      • To diagnose hardware problems:

      1. Connect your PC to another Wi-Fi network (for example, from your phone in hotspot mode).
      2. Try downloading Live-CD with another OS (for example, Linux Mint) and check if the internet works there.
      3. If possible, test a different Wi-Fi adapter (USB or PCI-e).
    ⚠️ Attention: On some motherboards (eg. ASUS ROG Strix or MSI B550) The integrated Wi-Fi module can be disabled in the BIOS. Go to the BIOS settings (Del/F2 when loading) and check if the option is activated «Wireless LAN» or «Onboard Wi-Fi».
