10 Reasons Why Windows Connects to Wi-Fi, But the Internet Doesn't Work – and How to Fix It

Introduction: Why Windows sees Wi-Fi, but there is no internet connection

You open your laptop, connect to your usual Wi-Fi network, but instead of the coveted Internet icon in the tray, a yellow triangle with an exclamation mark appears - "Connected, no internet access"The situation is familiar to many: Windows 10 or Windows 11 stubbornly refuses to provide network access, even though the router is working and other devices (smartphones, tablets) are connected without problems. What's wrong?

The cause could lie in your PC settings, or in issues with your router or ISP. In this article, we'll look into the matter. 10 most common reasons, why the computer connects to Wi-Fi, but the Internet does not work, and we will also give step-by-step instructions diagnostics and troubleshooting. From simple solutions (rebooting the router) to complex ones (manual configuration) DNS or reset the network stack).

Important: If the problem occurs suddenly, start by checking your other devices. If there's no internet on them either, the router or ISP is to blame. If it's only on your PC, look for the cause in the settings. Windows.

1. Router-side issues: reboot and basic diagnostics

The first thing to do is reboot the routerThis is a simple but effective way to fix temporary device issues. Unplug the router for 30 seconds, then plug it back in. Wait 1-2 minutes for the device to fully boot up, and then check the connection.

If rebooting doesn't help, pay attention to the router's indicators:

• 🔴 The red Internet indicator is on — problems on the provider’s side (cable break, technical work).
• 🟡 Yellow/flashing "Wi-Fi" — interference or channel overload is possible.
• 🟢 All the indicators are green, but there is no internet. — the problem is in the router or PC settings.

Also check if your router is blocking your computer MAC address. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1) and look at the list of connected devices. If your PC isn't there, add it manually or disable filtering by MAC.

2. DHCP Failure: Why Windows Doesn't Receive an IP Address

One of the common reasons for the lack of internet is incorrect operation of the DHCP protocol, which automatically assigns to your PC IP address, gateway And DNS. If Windows can't get these parameters, there will be a Wi-Fi connection, but no internet access.

To check this:

1. Open Command line (Win + R → enter cmd → Enter).
2. Run the command:

   ipconfig /all

3. Find the block with the name of your Wi-Fi network and check the fields:
   • IPv4 address — must be in the format 192.168.x.x or 10.x.x.x (If 169.254.x.x — DHCP didn't work).
   • Main gateway - must match IP router (usually 192.168.0.1 or 192.168.1.1).

If IP address starts with 169.254, Means, Windows I couldn't get it. Solutions:

• 🔄 Restart the service DHCP client:

  net stop dhcp && net start dhcp

• 🖥️ Assign IP manually (temporarily):
  1. Open Settings → Network & Internet → Wi-Fi → Configure adapter settings.
  2. Right-click on your Wi-Fi network → Properties → Internet Protocol version 4 (TCP/IPv4).
  3. Check the box Use the following IP address and enter:
     • IP address: 192.168.1.100 (if gateway 192.168.1.1).
     • Subnet mask: 255.255.255.0.
     • Main gateway: 192.168.1.1 (router address).
     • DNS: 8.8.8.8 And 8.8.4.4 (Google DNS).

What to do if manual IP configuration doesn't help?

If the internet still doesn't work after assigning a static IP, the problem may be with traffic blocking on the router (for example, parental controls or a firewall). Check your router settings in the "Security" or "Access Control" section.

3. Incorrect DNS settings: how to change servers and why it helps

DNS servers translate domain names (for example, google.com) V IP addressesIf they're not working properly, websites won't open even though you're connected to Wi-Fi. Often, changing them solves the problem. DNS to public servers Google or Cloudflare.

To change DNS:

1. Go to Settings → Network & Internet → Wi-Fi → Configure adapter settings.
2. Right-click on your Wi-Fi network → Properties → Internet Protocol version 4 (TCP/IPv4).
3. Select Use the following DNS server addresses and enter:
   • For Google DNS: 8.8.8.8 And 8.8.4.4.
   • For Cloudflare: 1.1.1.1 And 1.0.0.1.

Click OK and restart your computer.

If after the shift DNS The internet is working again, but the problem was with the ISP's servers. To reset the settings to automatic, select Obtain DNS server address automatically.

4. Outdated or corrupted Wi-Fi adapter drivers

Drivers are software that enables interaction Windows with the hardware. If they are outdated, damaged, or conflict with the system, Wi-Fi may connect, but the internet will not work. This is especially true after an update. Windows or replacing the adapter.

To check and update drivers:

1. Open device Manager (Win + X → device Manager).
2. Expand the section Network adapters.
3. Find your Wi-Fi adapter (e.g. Intel Wi-Fi 6, Qualcomm Atheros, Realtek RTL8821CE).
4. Right click → Update driver → Automatic search.

If automatic update does not help:

• 🔍 Download the driver from official website of the manufacturer (do not use third-party sources!).
• 🗑️ Uninstall the current driver (Remove device V Device Manager), then install a new one.
• 🔄 Restart your computer.

For laptops HP, Lenovo, Dell And ASUS It's better to download drivers from the laptop manufacturer's website, not the Wi-Fi chip manufacturer's website. For example, for Lenovo Legion - With support.lenovo.com.

Make sure the adapter is displayed in the Device Manager without an exclamation mark|Update the driver using Automatic Search|Download the driver from the manufacturer's official website|Remove the old driver before installing the new one|Restart the PC after installation-->

5. Network profile conflict or reset of network settings

Windows 10/11 Saves settings for each Wi-Fi network in a separate profile. Sometimes these profiles become corrupted, causing connection issues. The solution is delete network profile and reconnect.

How to delete a Wi-Fi profile:
