2. Quick Fixes (Start Here)

Before doing advanced steps, try these simple but effective fixes:

2.1 Turn WiFi Off → On

  • Click the WiFi icon in the bottom-right.
  • Turn WiFi Off, wait 10 seconds.
  • Turn WiFi On.

2.2 Restart Your Laptop

Restarting resets the Windows network stack and fixes many temporary issues.

2.3 Enable Airplane Mode → Disable

  • Click the WiFi/Volume popup.
  • Enable Airplane Mode → wait 5 seconds → disable.

2.4 Forget and Reconnect to WiFi

  • Settings → Network & Internet → WiFi

2.5 Check if WiFi is disabled via function key

  • Try pressing Fn + (WiFi key) — often F2, F3, F5, F7, or with antenna icon.

3. Check Your Router + Internet Connection

Sometimes the issue is not Windows — it’s your router or ISP.

3.1 Restart Your Router

  • Turn off router’s power.
  • Wait 15 seconds.
  • Turn it on again.

3.2 Check Other Devices

If your phone also cannot connect, the router or ISP is the problem.

3.3 Move Closer to Router

Low signal causes slow speeds or failure to connect.

3.4 Change Router WiFi Band

Try switching between:

  • 2.4GHz (longer range, slower)
  • 5GHz (faster, shorter range)

4. Windows 11 Network Troubleshooting

4.1 Use Windows Built-In Troubleshooter

4.2 Enable WiFi Adapter Manually

  • Right-click Start → Device Manager
  • Network Adapters
  • Right-click your WiFi device → Enable

4.3 Restart Network Services

  • Press Windows + R → type services.msc
  • Restart these:
    • WLAN AutoConfig
    • Network Connections
    • DHCP Client
    • DNS Client

5. Update, Reset, or Reinstall WiFi Drivers

5.1 Update Drivers Automatically

  • Right-click Start → Device Manager

  • Laptop Manufacturer’s website

6. Network Reset via Command Prompt (Advanced)

This resets TCP/IP stack, DNS cache, and network configurations. Very effective.

9. Hardware-Related Fixes

9.1 Check Physical WiFi Switch

Some older laptops have a physical WiFi switch — make sure it's ON.

9.2 Antenna Cable Loose (Laptop Repair Scenario)

Inside a laptop, WiFi antennas connect to the wireless card via two cables. If they become loose, signal becomes weak or drops completely.

9.3 Replace the WiFi Card (Easy Upgrade)

You can replace internal WiFi modules with modern ones that support WiFi 6 or WiFi 6E.

  • Intel AX200 / AX210
  • Realtek WiFi 6 modules

Works great for laptops with accessible M.2 WiFi slots.

FAQ: Windows 11 WiFi Issues

1. Why is my WiFi suddenly not working?

Most of the time, it’s due to driver issues, router problems, Windows updates, or corrupted network settings.

2. Why does WiFi keep disconnecting?

Causes include power-saving settings, weak signal, driver conflicts, or interference from other devices.

3. Why can’t Windows 11 detect my WiFi network?

Your WiFi adapter may be disabled, the router SSID is hidden, or a driver issue is preventing detection.

4. Should I reinstall Windows?

Only if all troubleshooting and driver fixes fail. Resetting Windows usually solves deep network corruption.

5. Will changing DNS make WiFi faster?

It won’t increase WiFi speed, but it can improve page loading and fix connectivity problems caused by DNS errors.
