Troubleshooting a laptop that won't connect to Wi-Fi involves addressing various potential issues:

Check Wi-Fi Switch/Function Key: Ensure that the laptop's Wi-Fi switch is turned on or use the designated function key (often labeled F2 or F12) to enable Wi-Fi.

Verify Airplane Mode is Off: Check if Airplane Mode is disabled. This mode turns off all wireless communication, including Wi-Fi.

Restart Your Laptop and Router: Power cycle both your laptop and Wi-Fi router. Rebooting devices can resolve temporary connectivity issues.

Check Wi-Fi Network Availability: Confirm that the Wi-Fi network is available and not hidden. If possible, try connecting to a different network to isolate the issue.

Update Wi-Fi Drivers: Outdated or incompatible Wi-Fi drivers can cause connectivity problems. Visit the laptop manufacturer's website or use Device Manager to update the drivers.

Forget and Reconnect to Wi-Fi Network: In the Wi-Fi settings, forget the problematic network and reconnect by entering the password again. This can refresh the connection.

Reset TCP/IP Stack: Open the Command Prompt as an administrator and type the command "netsh int ip reset" to reset the TCP/IP stack.

Disable Firewall/Antivirus: Temporarily disable the firewall or antivirus software. In some cases, security software may block Wi-Fi connections.

Check IP Configuration: Open Command Prompt and type "ipconfig /release" followed by "ipconfig /renew" to refresh the IP configuration.

Seek Professional Help: If the issue persists, consider seeking assistance from the laptop manufacturer's support or a professional technician to diagnose and address potential hardware-related problems.

By systematically addressing these common solutions, you can often troubleshoot and resolve issues preventing your laptop from connecting to Wi-Fi.
