How to Fix Wifi Not Working on PC?

How to Fix Wifi Not Working on PC?: If you’re experiencing Wi-Fi connectivity issues on your PC, here are steps to help you troubleshoot and fix the problem:

1. Check Hardware and Connections:

• Ensure that your Wi-Fi adapter is properly installed and seated in the correct slot.
• If you’re using a USB Wi-Fi adapter, make sure it’s connected properly.

2. Restart Your PC and Router:

• Sometimes, a simple restart can resolve connectivity issues. Restart both your PC and your Wi-Fi router.

3. Check Wi-Fi Switch or Function Key:

• Some laptops have a physical switch or function key (e.g., Fn + F2) to enable or disable Wi-Fi. Make sure it’s turned on.

4. Update Wi-Fi Drivers:

• Outdated or incompatible Wi-Fi drivers can cause connectivity problems. Visit the manufacturer’s website or use Windows Update to ensure your drivers are up to date.

5. Forget and Reconnect to the Wi-Fi Network:

• Go to “Settings” > “Network & Internet” > “Wi-Fi.”
• Click on the network you’re having trouble with and select “Forget.” Then reconnect by entering the password.

6. Check Network Password:

• Ensure that you’re entering the correct Wi-Fi password. Typos or incorrect passwords can lead to connection failures.

7. Run the Network Troubleshooter:

• Go to “Settings” > “Update & Security” > “Troubleshoot.”
• Run the “Internet Connections” troubleshooter.

8. Check for Interference:

• Other electronic devices, appliances, and neighboring Wi-Fi networks can interfere with your Wi-Fi signal. Move away from potential sources of interference.

9. Change Wi-Fi Channel:

• Access your router settings (usually through a web browser) and change the Wi-Fi channel to reduce interference.

10. Disable and Re-enable Wi-Fi Adapter:

• In “Device Manager,” find your Wi-Fi adapter, right-click, and choose “Disable.” After a few seconds, right-click again and choose “Enable.”

11. Check Power Management Settings:

• In “Device Manager,” find your Wi-Fi adapter, right-click, and go to “Properties.”
• Under the “Power Management” tab, uncheck the option that allows the computer to turn off the device to save power.

12. Reset TCP/IP Stack:

• Open Command Prompt as an administrator.
• Run the following commands one by one:

netsh winsock reset
netsh int ip reset

13. Update Router Firmware:

• Visit the router manufacturer’s website and check for firmware updates. Follow their instructions to update the router firmware.

14. Check Firewall/Antivirus Settings:

• Some security software may block Wi-Fi connections. Temporarily disable your firewall or antivirus and check if the issue persists.

15. Restore to a Previous State:

• If the problem started recently, you can use System Restore to revert your system to a state where Wi-Fi was working.

16. Contact Support:

• If none of the above steps work, it’s advisable to contact your router manufacturer’s support or the PC manufacturer’s support for further assistance.

By following these steps, you should be able to troubleshoot and fix most Wi-Fi connectivity issues on your PC.
