Wi-Fi Connected But No Internet (Windows) — What It Means & How to Fix It

What Does This Error Mean?

When Windows shows a connected Wi-Fi icon but you cannot browse the internet, the problem is almost always one of three things: a DNS failure, an ISP outage, or a Windows network stack problem. Your device is on the local network — but the route to the internet is broken somewhere.

Affected Models

Windows 10
Windows 11

Common Causes

The ISP's DNS servers are down, so domain names cannot be resolved to IP addresses
The ISP is experiencing an outage and the router has no internet connection
Windows TCP/IP stack has become corrupted and is routing traffic incorrectly
A proxy server or VPN is configured in Windows and is not working
The router is connected to the modem but the modem lost its upstream connection

How to Fix It

Test on another device. If your phone has internet on the same Wi-Fi, the problem is Windows. If nothing has internet, restart the modem and router and check for an ISP outage.

This single test tells you where to focus your troubleshooting.
Flush DNS and renew your IP address. Open Command Prompt as Administrator and run: ipconfig /flushdns — ipconfig /release — ipconfig /renew. Then close and reopen your browser.

Stale DNS and IP data is a very common cause of 'connected but no internet' on Windows.
Change your DNS servers to Google or Cloudflare. Press Windows + R, type ncpa.cpl, right-click your Wi-Fi adapter > Properties > IPv4 > Use the following DNS: 8.8.8.8 and 8.8.4.4. Click OK.

If the ISP's DNS is down, switching to a third-party DNS immediately restores browsing.
Check if a proxy is set in Windows. Go to Settings > Network & Internet > Proxy. Make sure 'Use a proxy server' is turned OFF unless you intentionally set one.

A broken proxy setting blocks all internet traffic even though the Wi-Fi connection is live.
Run a full network reset. Open Command Prompt as Administrator and run: netsh winsock reset — netsh int ip reset — ipconfig /flushdns — Restart your PC.

This rebuilds Windows networking from scratch and resolves deep configuration corruption.

When to Call a Professional

If restarting the modem and router does not restore internet and other devices also have no internet, call your ISP. If only your Windows PC is affected, run the network reset steps below. Persistent issues after all fixes may require a network technician to check the PC for deeper configuration problems.

Frequently Asked Questions

What is DNS and why does it matter for internet access?

DNS is the system that translates website names into the numeric addresses computers use. When you type 'google.com', DNS converts it to '142.250.x.x' so your computer knows where to go. If DNS is broken, website names cannot be resolved and pages fail to load — even though the internet connection itself is working.

Can a VPN cause this problem?

Yes. If a VPN is active and its connection drops or its servers go down, it blocks all internet traffic while leaving the Wi-Fi status showing as connected. Disable the VPN and test — if internet returns, the VPN is the cause.

I ran all the commands but internet still does not work. What next?

Check if the problem is consistent across all browsers and apps, or just one. If just one app fails, the issue is app-specific, not your internet connection. If everything fails, try a wired ethernet connection. If wired also has no internet, contact your ISP — the problem is outside your PC.
