Wifi Not Working On Windows 7/8/10/11

1. Check Physical Connections:

• Ensure that your Wi-Fi router is powered on and the cables are securely connected.
• Check if there are any physical obstructions that may affect the Wi-Fi signal.

2. Run Windows Troubleshooter:

• Right-click on the Wi-Fi icon in the system tray.
• Select “Troubleshoot problems” to run the Windows Network Troubleshooter.

3. Check Wi-Fi Signal Strength:

• Ensure you are within the range of your Wi-Fi router.
• If the signal strength is weak, consider repositioning the router or using a Wi-Fi extender.

4. Restart Your Router and Modem:

• Power off your router and modem.
• Wait for at least 10 seconds before turning them back on.
• Allow the devices to fully restart and try connecting again.

5. Disable and Enable Wi-Fi:

• Right-click on the Wi-Fi icon and select “Disable.”
• After a few seconds, right-click again and select “Enable.”

6. Check Network Password:

• Ensure you are entering the correct Wi-Fi network password.
• Consider resetting the Wi-Fi password if necessary.

7. Update Network Drivers:

• Open the Device Manager (right-click on the Windows icon, select “Device Manager”).
• Under “Network adapters,” locate your wireless network adapter.
• If there’s a yellow triangle, right-click and choose “Update driver.”

8. Reset TCP/IP Stack:

• Open Command Prompt as an administrator.
• Type the following commands and press Enter after each:
  
  perlCopy code

  netsh winsock reset
netsh int ip reset
ipconfig /release


  ipconfig /renew

9. Check for Interference:

• Other electronic devices or neighboring Wi-Fi networks may cause interference. Consider changing the Wi-Fi channel on your router.

10. Disable Security Software:

• Temporarily disable antivirus or firewall software to check if they are causing the connection issue.

11. Check DNS Settings:

• Open Command Prompt and type:
  
  bashCopy code

  ipconfig /flushdns
ipconfig /renew


12. Investigate Additional Devices:

• Check if other devices on the same network are experiencing issues. If yes, it may be a router problem.

13. Verify MAC Address Filtering:

• Check if your router is using MAC address filtering. Ensure your device’s MAC address is allowed.

14. Update Router Firmware:

• Visit the router manufacturer’s website and check for firmware updates. Apply updates if available.

15. Consider System Restore:

• If the issue started recently, consider using System Restore to revert your system to a previous state.

16. Contact ISP:

• If all else fails, contact your Internet Service Provider (ISP) for assistance. There may be an issue on their end.

Note:

Always be cautious when disabling security software, and only do so temporarily for troubleshooting purposes. Re-enable it once the troubleshooting is complete.
