Fix Can’t Connect Wi-Fi in Windows 11

If Windows 11 won’t connect to Wi‑Fi, the fix is usually a combination of turning Wi‑Fi off and on, running the built‑in network troubleshooter, and resetting the network stack. This guide walks through the most effective fixes in order, from quick checks to deeper resets, so you can get back online without guessing.

Why Windows 11 Wi‑Fi Fails

Windows 11 uses the same underlying Wi‑Fi stack as Windows 10, but the Settings app has been redesigned. Most connection problems fall into one of these categories:

• Driver issues – outdated or corrupted wireless adapter drivers are the #1 cause.
• Network profile corruption – saved Wi‑Fi profiles can become stale or corrupted.
• IP address conflicts – the router may not assign a valid IP, or the PC holds onto an old one.
• Power management – Windows may turn off the adapter to save power, interrupting the connection.
• Router or ISP problems – the issue might not be your PC at all.
• Windows updates – a recent update can sometimes break Wi‑Fi, though Microsoft usually patches quickly.

Before diving into advanced fixes, try the simplest: restart your PC and your router. Unplug the router for 30 seconds, plug it back in, and wait for it to fully boot. This clears many temporary glitches.

Quick Checks and Basic Fixes

1. Toggle Wi‑Fi off and on – Click the network icon in the system tray, click the Wi‑Fi button to turn it off, wait 5 seconds, then turn it back on.
2. Check Airplane mode – Press Win + A to open Quick Settings. If Airplane mode is on, turn it off.
3. Forget and reconnect – Go to Settings → Network & internet → Wi‑Fi → Manage known networks. Select your network, click Forget, then reconnect by selecting the network and entering the password.
4. Run the network troubleshooter – Go to Settings → System → Troubleshoot → Other troubleshooters, click Run next to “Network and Internet.” Follow the prompts.
5. Restart the router – Power cycle your router and modem. Wait for all lights to stabilize.

If Wi‑Fi still doesn’t connect, move to the driver and network reset steps below.

Update or Reinstall the Wi‑Fi Driver

Driver problems are common after a Windows feature update. Here’s how to fix them:

1. Right‑click the Start button and select Device Manager.
2. Expand Network adapters. Look for your Wi‑Fi adapter (often named “Intel Wi‑Fi”, “Realtek”, or “Qualcomm”).
3. Right‑click it and select Update driver → Search automatically for drivers. If Windows finds nothing, try the next step.
4. Right‑click again and select Uninstall device. Check “Delete the driver software for this device” if it appears, then click Uninstall.
5. Restart your PC. Windows will automatically reinstall the driver.

If that doesn’t work, visit your laptop manufacturer’s support website (Dell, HP, Lenovo, etc.) and download the latest Wi‑Fi driver for your exact model. Install it and restart.

Reset the Network Stack

If drivers are fine, the network configuration may be corrupted. Windows 11 has a built‑in network reset that clears all network adapters and sets them back to default.

1. Go to Settings → Network & internet → Advanced network settings.
2. Click Network reset.
3. Click Reset now and confirm. Windows will restart your PC.

After the reset, you’ll need to reconnect to Wi‑Fi by entering your password again. This also resets VPN connections and any static IP settings you may have configured.

If you prefer command line, you can run these commands in an elevated Command Prompt (right‑click Start → Terminal (Admin)):

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart after running them.

Disable Power Saving on the Adapter

Windows sometimes turns off the Wi‑Fi adapter to save battery, which can cause disconnects or failure to connect. To disable this:

1. Open Device Manager and expand Network adapters.
2. Right‑click your Wi‑Fi adapter and select Properties.
3. Go to the Power Management tab.
4. Uncheck “Allow the computer to turn off this device to save power.”
5. Click OK and restart.

Check IP and DNS Settings

If you can connect but get “No internet,” the problem may be IP or DNS. Try these:

• Use automatic IP – In Settings → Network & internet → Wi‑Fi → your network → IP assignment, click Edit and set to Automatic (DHCP).
• Change DNS to public DNS – In the same IP settings, set DNS to manual and use 8.8.8.8 and 8.8.4.4 (Google) or 1.1.1.1 and 1.0.0.1 (Cloudflare).
• Release and renew IP – Run ipconfig /release then ipconfig /renew in Command Prompt.

When to Suspect the Router or ISP

If your PC still can’t connect, test another device (phone, tablet) on the same Wi‑Fi. If those also fail, the problem is the router or internet service. Common router fixes:

• Reboot the router.
• Update the router’s firmware (check the manufacturer’s app or web interface).
• Change the Wi‑Fi channel in router settings to avoid interference.
• If the router is old, consider replacing it.

If only your PC fails but other devices work, the issue is your PC’s adapter or configuration.

Frequently Asked Questions

Why does Windows 11 say “Can’t connect to this network”?

This error usually means the Wi‑Fi password is wrong, or the network profile is corrupted. Forget the network and reconnect, double‑checking the password. If it persists, run the network troubleshooter and then reset the network stack.

How do I reset Wi‑Fi settings in Windows 11?

Go to Settings → Network & internet → Advanced network settings → Network reset. Click Reset now and restart. This removes all saved Wi‑Fi networks and resets all network adapters to default.

Why is my Wi‑Fi adapter not showing in Device Manager?

If the adapter is missing, it may be disabled in BIOS or the driver is uninstalled. Check BIOS settings for “Wireless LAN” and enable it. You can also try “Scan for hardware changes” in Device Manager’s Action menu.

Will a system restore fix Wi‑Fi issues?

If the problem started after a recent change (driver update, Windows update), a system restore to a point before that change can help. Go to Control Panel → Recovery → Open System Restore and choose a restore point.

Can a VPN block Wi‑Fi in Windows 11?

Yes, VPN software can interfere with network connections. Temporarily disable or uninstall the VPN and test. If Wi‑Fi works, reconfigure the VPN or try a different VPN client.

How do I check if my Wi‑Fi driver is corrupted?

Open Device Manager, right‑click the adapter, and select Properties. On the Driver tab, click Driver Details. If you see errors, or the driver date is very old, update or reinstall it. You can also run sfc /scannow in Command Prompt to repair system files.
