Why Wi-Fi is connected but there's no internet on a Windows 10 laptop: A complete troubleshooting guide

The situation is familiar to many: you connect to your home or office Wi-Fi network, but instead of the usual access to websites and instant messengers, Windows 10 stubbornly displays a yellow triangle with an exclamation mark and the inscription "No internet access"Meanwhile, other devices—smartphones, tablets, TVs—work fine. What's wrong?

The problem could lie in your laptop's settings, your router's settings, or even your internet provider's settings. In this article, we'll look into it. all possible reasons — from the mundane (an unpaid internet bill) to the technical (a failure in the TCP/IP protocol stack). You will receive step-by-step instructions with pictures, diagnostic checklists, and tips on how to prevent the problem from recurring.

Important: If the error appears after updating Windows or installing new software, first check network card drivers And IPv4 protocol settingsThese two factors are responsible for 60% of malfunctions.

1. Check the obvious: router, provider, and balance

Before digging into Windows settings, rule out external causes. Start with the simplest:

• 💡 Reboot your routerUnplug it from the power outlet for 30 seconds, then plug it back in. Wait until it fully boots up (the indicators should be steady, not flashing).
• 📱 Check the internet on other devicesIf no device connects, the problem is with your ISP or router.
• 💰 Make sure the invoice is paidLog in to your provider's account or call support. Sometimes access is blocked due to outstanding debts, but notifications are delayed.
• 🔌 Check the cablesIf your router is connected to the internet via a cable (not LTE), make sure it is firmly inserted into the port. WAN (usually highlighted in blue).

If the internet works after rebooting the router, the problem was a temporary glitch in the device's DHCP server. If not, we move on.

⚠️ Attention: On some routers (for example, TP-Link Archer C6 or ASUS RT-AX58U) After resetting the settings, you may need to reconfigure your network. Don't worry if Wi-Fi disappears from the list—just connect to the network with your router's model name (usually indicated on the sticker on the bottom).

2. Diagnosing network connections in Windows 10

Windows 10 has built-in network diagnostic tools. Here's how to use them:

Step 1. Right-click on the Wi-Fi icon in the tray (bottom right corner of the screen) and select TroubleshootingThe system will automatically check the main parameters and suggest solutions.

Step 2. If automatic diagnostics did not help, open Settings → Network & Internet → Status and press Network ResetThis will reset all network settings to factory defaults, but delete saved Wi-Fi passwords.

Step 3. Check it out IP address your laptop:

1. Click Win + R, enter cmd and press Enter.
2. In the command line, run:

   ipconfig /all

3. Find the block with the name of your Wi-Fi network. Check the lines IPv4 address, Main gateway And DNS servers.

If instead of a normal IP (for example, 192.168.1.100) you see 169.254.x.x — this means the laptop hasn't received an address from the router. Causes and solutions are in the next section.

3. DHCP Issues: Why Your Laptop Isn't Received an IP Address

Protocol DHCP Responsible for automatically assigning IP addresses to devices on the network. If it's not working properly, Windows 10 won't be able to connect to the internet, despite a visible Wi-Fi connection.

Reasons for DHCP failure:

• 🔄 IP address conflict (two devices are trying to use the same address).
• ⚙️ Incorrect router settings (DHCP server is disabled or the address pool is limited).
• 🖥️ Windows network stack failure (for example, after an update).
• 🛡️ Blocked by antivirus or firewall (rarely, but it happens).

How to fix:

1. Restart the DHCP service:

   net stop dhcp
   net start dhcp

2. Assign IP manually (temporary solution):
   1. Open Settings → Network & Internet → Wi-Fi → Manage known networks.
   2. Select your network, click "Properties".
   3. Scroll to IP Settings and select "Manually".
   4. Enter:
      • IP address: 192.168.1.100 (if the router 192.168.1.1)
      • Subnet mask: 255.255.255.0
      • Gateway: 192.168.1.1 (your router's IP)
      • DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)

ipconfig /flushdns

A critical detail: if the internet works after manually assigning an IP address, the problem is definitely DHCP. In this case, check your router settings (section 5) or update your network card driver (section 6).

4. DNS failure: websites won't open, but Skype works

If you have some programs opening (for example, Skype, Telegram, Steam), but browsers and most websites don't work - it's my fault DNS serverIt's like the internet's phone book: if it's broken, you can't dial a website, even if you have a connection.

How to check:

1. Open command prompt and run:

   ping 8.8.8.8
   ping ya.ru

2. If the first one ping one goes through (there is an answer), but the second one doesn’t, the problem is in the DNS.

Solutions:

• 🔄 Change DNS manually:
  1. Open “Settings” → “Network & Internet” → “Wi-Fi” → “Change adapter settings”.
  2. Right-click on your Wi-Fi adapter → "Properties".
  3. Select Internet Protocol Version 4 (TCP/IPv4) → Properties.
  4. Check the box "Use the following DNS server addresses" and enter:
     • 8.8.8.8 (Google)
     • 1.1.1.1 (Cloudflare)
• 🛠️ Clear your DNS cache (as in section 3).
• 🔍 Check the file hostsSometimes viruses or programs make changes to it:
  1. Open C:\Windows\System32\drivers\etc\hosts in notepad (as administrator).
  2. Delete all lines except 127.0.0.1 localhost.

⚠️ Attention: Some providers (eg Rostelecom or Beeline) link access to their DNS servers. If you lose internet access completely after changing your DNS, reset your settings and contact support.

5. Router settings: what could go wrong

If the problem only occurs on one laptop, and other devices are working fine, Windows settings or drivers are to blame. But if the internet connection is lost on all devices, the router is the problem. Here's what to check:

How to access router settings:

1. Find out the IP address of the router (usually 192.168.1.1 or 192.168.0.1, indicated on the sticker).
2. Open your browser and enter this IP in the address bar.
3. Enter your login and password (by default it is often admin/admin or admin/password).

If you can’t log in, reset the router to factory settings using the button Reset (Hold for 10-15 seconds). After the reset, set up your internet connection again (connection details are usually included in your contract with your provider).

ipconfig /all

6. Network card drivers: updating and rolling back

Driver failures are one of the most common causes of the problem. Wi-Fi without internet access. Especially if the error appeared after a Windows update or installing new software.

How to check the driver:

1. Click Win + X and select "Device Manager".
2. Expand the section Network AdaptersFind your Wi-Fi adapter (usually contains the words Wireless, Wi-Fi, 802.11 or brand name: Intel, Qualcomm, Realtek).
3. If there is a yellow exclamation mark next to the adapter, the driver is not working properly.

Solutions:

• 🔄 Update your driver:
  1. Right-click on the adapter → "Update Driver" → "Search Automatically".
  2. If Windows does not find updates, download the driver from the laptop manufacturer's website (for example, Lenovo Support, HP Drivers) or chipset (for example, Intel Download Center).
• 🔙 Roll back the driver (if the problem appeared after the update):
  1. In the Device Manager, click on the adapter → Properties → Driver → Roll Back Driver.
