Keep your Wi-Fi password at hand, because some steps make Windows forget the network. If possible, download your Wi-Fi adapter driver on another device or via a cable first. If Windows cannot start, see the startup guide.
Work through these checks
0 of 7 complete01Test another device and restart the router
If no device has internet, the problem is the router or the provider, not the PC.
- Check whether a phone or another computer on the same Wi-Fi can open websites.
- Unplug the router and the modem, wait at least 30 seconds, plug the modem back in, wait for its lights to settle, then plug in the router.
- If your router offers both a 2.4 GHz and a 5 GHz network, try the other one.
Websites load again on the PC.
If it does not helpIf no device has internet even after the restart, contact your internet provider. If only this PC fails, continue with step 2.
02Forget the network and reconnect
A saved network profile with old settings can keep the connection from working.
- Make sure Airplane mode is off (Settings > Network & internet > Airplane mode).
- Open Settings > Network & internet > Wi-Fi > Manage known networks, select your network and choose Forget.
- Connect to the network again and enter the password.
The PC connects with internet access.
If it does not helpIf it still shows no internet, continue with step 3.
03Run the network troubleshooter
The troubleshooter checks the adapter, IP settings and DNS automatically.
- On Windows 11, run the network troubleshooter in the Get Help app (search "Get Help" and type "network troubleshooter").
- On Windows 10, open Settings > Network & Internet > Status > Network troubleshooter.
The troubleshooter finds and fixes the problem.
If it does not helpNote any problem it reports but cannot fix, then continue.
04Reset the IP configuration and DNS cache
Microsoft's Wi-Fi troubleshooting includes these commands to renew the address and clear network settings.
- Search for cmd, right-click Command Prompt and choose Run as administrator.
- Run these commands one at a time: netsh winsock reset, netsh int ip reset, ipconfig /release, ipconfig /renew, ipconfig /flushdns.
- Restart the PC.
The PC gets a valid address and websites load.
If it does not helpTo check the connection to the router, run ipconfig, note the Default Gateway and run ping followed by that address.
05Check proxy and VPN settings
A leftover proxy or a VPN that is not connected properly blocks traffic while Wi-Fi itself works.
- Open Settings > Network & internet > Proxy and turn off Use a proxy server unless you need one.
- Disconnect or quit any VPN app, and pause third-party firewall or security software to test.
- Check which DNS servers are used: run ipconfig /all and look at DNS Servers. Unknown servers set by a program can be the cause.
Turn your security software back on after the test.
Websites load with the proxy and VPN off.
If it does not helpIf a program set its own DNS or proxy, change its settings or uninstall it. If websites fail with a DNS error, see the DNS_PROBE_FINISHED_NXDOMAIN guide on this site.
06Reinstall the Wi-Fi adapter driver
A damaged or outdated driver can connect to the router but fail to pass traffic reliably.
- Open Device Manager, expand Network adapters, right-click the Wi-Fi adapter and choose Uninstall device.
- Tick Attempt to remove the driver for this device, click Uninstall and restart the PC; Windows reinstalls the adapter.
- If that does not help, install the driver from your PC or laptop maker's website.
- In the adapter's Properties > Power Management, clear Allow the computer to turn off this device to save power.
Save a copy of the maker's driver first, in case Windows cannot reinstall it automatically.
The adapter works and stays connected.
If it does not helpThen run Windows Update and restart.
07Use network reset as a last resort
Network reset removes and reinstalls all network adapters and their settings.
- On Windows 11, open Settings > Network & internet > Advanced network settings > Network reset and choose Reset now.
- The PC restarts; reconnect to Wi-Fi afterwards.
Network reset removes saved Wi-Fi networks, and you may need to reinstall VPN software or Hyper-V virtual switches. It may also set known networks to Public.
The PC connects to the internet normally.
If it does not helpIf it still fails while other devices work, test the PC on another network to rule out a router setting such as MAC filtering.
Possible causes
- The router, modem or internet connection is down
- Invalid IP address or DNS settings on the PC
- A proxy, VPN or security program blocking traffic
- A Wi-Fi adapter driver problem or power saving
- Damaged network settings in Windows
