The main reason why laptops can't connect to the internet via a LAN cable is usually due to the Ethernet driver that has not been installed. This problem is very easy to solve by finding the right driver and installing it.

However, sometimes the problem is more than that, even though we have installed the driver, the connection still doesn't work. If you are in a room where there are several other computers connected to the same network, try checking first if the other computers are experiencing the same thing?

If the internet that has the problem is only the laptop or PC you are using, then you can be sure the problem is with your computer, not with the network.

On this occasion, bingGo will try to provide several solutions that can be tried to solve a laptop that can't connect to the internet with a LAN cable.

1. Turn on the connection from Ethernet

The thing that most often causes laptops, unable to connect to the internet with a LAN cable is because the ethernet connection is disabled.

When experiencing this problem, then making sure the internet is active is the first thing you should do.

First, go to Control Panel => select the Network and Sharing Center menu.

Then click on the Change adapter settings tab.

A new window will open, there find the connection labeled Ethernet or Local Area Network.

See if the status is enabled or disabled. If the icon is gray and there is a Disabled label under it, then the ethernet on your laptop is turned off.

All we need to do is turn it on by right clicking => select Enable.


Wait a moment for the Ethernet to turn on successfully, then reconnect the LAN cable to your laptop.

2. Check the Ethernet driver

Damaged or missing ethernet drivers are also often the cause of laptops, unable to connect to the connection with a LAN cable. If the Ethernet driver is missing, the characteristic is, that the network icon on the taskbar has a red cross.

As long as installing the appropriate internet driver, the LAN connection will not be able to be connected. Therefore the only solution to solve it is to find and install the right driver.

You can try to find the driver manually with the following steps:

First open the Device Manager by pressing Windows key + R on the keyboard => type devmgmt.msc.

After the Device Manager program opens select the device called Network adapters => click on the little arrow next to it to expand it.

Check if there is a device called Ethernet controller?

If it is not there, click expand on the Other devices menu , you will see the Ethernet Controller device with a yellow warning sign, this means that the device driver has not been installed, damaged, or deleted.


All we have to do is find and install the appropriate driver.

Right click on Ethernet Controller => select Properties.

Then click on the Details tab => in the Property section, select Hardware Ids => Copy the second row in the Value column => Paste it into Notepad.


Then open the driver finder site, you can use this site:

Paste the Hardware Ids that you copied earlier in Notepad into the available column on the site => click the Search button.

Wait for the results to come out. Next, you download the driver in zip format.

After that, install the downloaded driver. If you don't know how to install the driver in zip format, then you can see the steps here:

After the ethernet driver has been installed, try again to plug the LAN cable into the laptop. You should now be able to connect to the internet normally again.

3. Check the cable to the router

One end of the LAN cable used must be connected to a router, modem, or switch to get an internet connection. When the problem of the laptop not being able to connect to the internet occurs, try to check the end of the cable connected to the router and make sure it is plugged in correctly.

Connections can be lost due to loose or improperly connected cables. You can confirm this by first disconnecting and then reconnecting.

4. Make sure the LAN cable you are using is not damaged

After making sure the end of the cable connected to the router is correct, but still unable to connect to the internet, then the next thing to check is the LAN cable used.

First, if you are in a room where there are multiple laptops or PCs connected to the same network, try using a LAN cable connected to another computer then try connecting to your computer. If you find that the internet is successfully connected, then you can be sure that the problem is your LAN cable.

Second, if there is no other computer, then you can use another cable. If using another cable, it turns out that it can connect the computer to the internet, then there is no doubt that the problem is the old cable.

Damage to the LAN cable can be due to a broken or loose cable from the head connector (RJ45). You can fix this by first removing the RJ45 connector, peeling the cable and then connecting it back to the connector head, then cutting the remaining cable neatly using a crimping tool (special pliers for LAN cables). Do this for both ends of the cable.

It's a different story if the broken part of the cable is in the middle, repairing it is not easy, especially for beginners. It will be easier if you replace the LAN cable with a new one.

5. Restart and reset the router

After making sure the LAN cable used is good and is properly connected at both ends, but the internet still can't, then the thing to try next is to restart and reset the modem.

First restart the router by turning it off and then turning it on again. Wait a moment for the router to turn back on and the indicator light shows that it is connected to the network. See if the internet connection on the laptop is okay.

If you still can't, then you can reset it. To reset the router, the method varies, depending on the type and brand of router used. You can see it in the manual or on the router vendor site you are using.

6. Run the Internet Troubleshooter

After doing the steps above correctly, it is likely that the internet on the laptop has been successfully connected. However, if you still can't, then the next step is to run the troubleshooter.

In Windows 10, the troubleshooter feature is powerful enough to find out what causes an error to occur, usually there are also recommendations that the user must do to fix it.

To run the internet troubleshooter on Windows 10 follow these steps:

First, go to the Settings menu => then select Update & Security.

Then click on the Troubleshoot tab => on the right side panel, select the Additional troubleshooters menu.

Click on Internet Connection => click the Run the troubleshooter button.


When finished, the screen will display a description of why the internet connection on the laptop has a problem. Follow the recommendations given by the troubleshooter to fix it.

Then go back to the Additional troubleshooter => Network adapter => click Run the troubleshooter button.


Wait for the process to finish, see if there are any problems detected by the troubleshooter, follow the repair recommendations provided.

7. Turn off VPN, Proxy, and Firewall

The next step in dealing with a LAN connection that can't be internet on a laptop is to temporarily turn off the VPN, Proxy, Firewall, and antivirus (if any). The goal is to check whether one of them is the cause of the internet connection not working.

First turn off the VPN and restore the internet connection using the standard configuration. If you use software, there is usually an on / off button that you can use. See if turning off the VPN connection can work again or not.

Then turn off the firewall for a while.

You do this by going to the Control Panel => select Windows Defender Firewall.

In the left pane, click the Turn Windows Defender Firewall on or off option.

Turn off the firewall on the private network and public network => click OK.


After that restart the computer, then check whether the internet connection can be connected normally again or not.

If it still doesn't work, then turn on the firewall again using the same steps as above.

Lastly, if you are using a third party antivirus. So try to disable the antivirus first and see if there are any changes. Certain configurations on the antivirus can sometimes cause internet connection blocking, therefore you should be more selective in choosing an antivirus.

8. Check IP and DNS configuration

Configuring the wrong IP Address and DNS can also be the cause of the laptop not being able to connect WiFi or LAN cables. When experiencing problems with your internet connection, one of the steps that must be taken is to ensure that the IP and DNS configurations are correct.

Follow these steps:

First, go to Control Panel => select Network and Sharing Center.

On the left panel, select Change adapter settings => right click on Ethernet => select Properties.

Select Internet Protocol Version 4 (TCP / IPv4) => click the Properties button.

You can select Obtain IP address automatically and Obtain DNS server address automatically to get an IP and DNS automatically.


However, if your network configuration requires a specific IP and DNS, then fill in the IP Address and DNS server according to the configuration on the network you are using. You can ask the network technician or IT who installed the network.

When done, close all setup windows. Then try to check whether the internet can run normally.

9. Flush DNS and reset TCP / IP

The next step to fixing a problematic internet connection with a LAN cable on a laptop is to clear the DNS cache and reset the TCP / IP configuration. This can be done using cmd (command prompt).

Follow these steps:

First open cmd with administrator access, how to press Windows key + R => type cmd => click OK.

After the cmd program opens, type the following commands one by one ending by pressing the enter key on each line.

netsh winsock reset

netsh int ip reset

ipconfig / release

ipconfig / renew

ipconfig / flushdns

When finished running all the above commands at the command prompt, restart the laptop to make sure everything is reloaded from scratch. After that try to connect again to the LAN network, the internet should now be able to connect.

Resetting the internet connection with cmd is also powerful enough to solve the No internet access problem when using WiFi.

The function of each command line above:

  • Netsh Winsock reset => functions to restore the windows socket configuration (wsock32.dll) to the default.
  • Netsh int IP resets => functions to reset the TCP / IP configuration and restore it to its default state.
  • Ipconfig / release => removes current IP configuration.
  • Ipconfig / renew => create a new IP configuration.
  • Ipconfig / flushdns => clears DNS cache.

10. Reset the PC

At this point, we have done almost all the methods available to solve the problem of internet connection on a laptop that cannot be connected to a LAN network. There is still one more solution that can be tried, namely resetting the PC.

PC reset is different from reinstalling Windows 10, we don't need a CD or ISO file, this feature is already in the default Windows 10 settings and can be used when a problem occurs that is difficult to find a solution to.

Will the data be lost after resetting the PC?

No, your data is still safe. You just have to choose the option not to delete data. However, all non-default applications will still be deleted, so after the reset you will have to install them again one by one.

Please follow the steps listed here:

11. Repair the Ethernet card

After doing all the steps above, but the problem has not been resolved, then at this stage we can already suspect that the hardware or hardware is damaged.

The hardware responsible for handling the connection with a LAN cable on a laptop is an Ethernet card. Just like other devices, the Ethernet card can also be damaged.

You can try to bring your laptop to a trusted computer service in your city. The technician will try to diagnose whether there is damage to the Ethernet card, whether it can be repaired or not, if not, then replacing a new one is the last solution you can do.

These are the solutions you can do to solve the problem of a laptop not being able to connect to the internet with a LAN cable. Hope you can help.
