Main Reasons Why HP LAN Port Stops Working

There can be multiple reasons behind this issue:

Disabled LAN adapter in settings
Corrupted or outdated LAN driver
Windows update conflict
Faulty Ethernet cable or router port
Dust or physical damage in LAN port
Motherboard LAN chip issue

Technicians at HP Laptop Service Center In Patna often find that many LAN issues are caused by simple settings or driver problems.

Step-by-Step Solutions You Can Try at Home

1. Check the Ethernet Cable and Router

Before checking the laptop, confirm the basics:

Try a different Ethernet cable
Use a different router port
Test the same cable on another laptop

If the cable works elsewhere, the issue is inside your HP laptop.

2. Enable LAN Adapter in Network Settings

Press Windows + R, type ncpa.cpl, and press Enter
Check if Ethernet is disabled
Right-click and select Enable

Many users find their LAN working immediately after this step.

3. Update or Reinstall LAN Driver

Press Windows + X → Device Manager
Expand Network Adapters
Right-click Ethernet adapter → Update driver
If not fixed, uninstall the driver and restart

This is one of the most common fixes suggested by HP Laptop Service Center In Patna.

4. Check BIOS Settings

Sometimes LAN is disabled in BIOS:

Restart laptop and press F10
Go to Advanced or System Configuration
Make sure LAN / Ethernet is enabled
Save and exit

5. Run Network Troubleshooter

Go to Settings → Network & Internet
Click Network Troubleshooter
Let Windows detect and fix issues automatically

This helps in software-level network errors.

When the Problem Is Hardware-Related

If none of the above steps work, the problem may be hardware-based, such as:

Damaged LAN port
Broken internal LAN connector
Motherboard LAN IC failure

In such cases, expert diagnosis is required. Visiting HP Laptop Service Center In Patna is recommended to avoid further damage.

Avoid bending or twisting the cable
Keep the LAN port clean and dust-free
Avoid liquid exposure near ports
Use a surge protector for power safety

Good handling can extend the life of your laptop ports.
