Step 2: Device Manager Inspection
Open Device Manager and check if the network adapter is listed. Follow these steps:

Step 4: Network Troubleshooter
Windows has a built-in network troubleshooter that can help diagnose and fix common network issues.
- Go to Settings > Update & Security > Troubleshoot.
- Click on Internet Connections and select Run the troubleshooter.
Step 5: Network Reset
Sometimes a network reset can resolve persistent issues.
- Navigate to Settings > Network & Internet > Status.
- Scroll down and click Network reset.

Step 6: Check for Physical Damage
Inspect the network adapter and associated cables for any visible damage. Replace damaged components if necessary.
Step 7: BIOS Settings
Ensure that the network adapter is enabled in the BIOS:
- Restart your computer and enter the BIOS/UEFI settings (usually by pressing F2, DEL, or another key during startup).
- Navigate to the network or integrated peripherals section.
- Make sure the network adapter is enabled.
Step 8: Malware and Antivirus Check
Run a comprehensive malware scan to ensure your system is not compromised by malicious software that could affect network connectivity.
Step 9: Reinstall Network Adapter
If the problem persists, try reinstalling the network adapter:
- Right-click on the network adapter in Device Manager and select Uninstall device.
- Restart your computer. Windows will attempt to reinstall the network adapter automatically.
Step 10: External Network Adapter
If all else fails, consider using an external USB network adapter as a temporary solution.
