Are you not able to connect to internet via wired connection? You are not the only one facing this problem. Sometimes, computer cannot recognize the wired connection either due to network traffic or due to failure of network driver or may be due to some other reasons. Some possible reasons behind the issues are discussed below in this tutorial, which would help you to diagnose and fix the issue.
Firstly, verify that whether you are able to connect to the internet via wireless or not. If you are able to access Internet through wireless, then there are two possible causes that arise, may be your LAN port is not working or LAN connection is disabled on your system. If the problem is relating to the LAN port, then you need to repair it or replace it with a new one. If that’s not the problem then you need to go to the BIOS setting and enable the LAN connection.
If wireless connection is not available then something is wrong with the network driver. Figure out if the network driver is working or not. If the driver has stopped working then you can just download the respective driver for your PC and install it. You can also try updating the existing network driver. To update driver go to the “My Computer” and right click on it and select manage. In the computer Management window click on the device manager to determine the type of driver installed and update it. Go to the driver properties to check whether it’s working or not.
Even after installing the driver if the problem still persists, then try Safe mode with networking.
Check the cable that is connected from PC to router and see if there is a light on the router associated with the cable port used, also check if you have a green/yellow light on the PC LAN port. Upon the start of PC keep tapping F8. On tapping, a menu appears choose safemode with networking. Try accessing Internet in the safemode.
If the problem still persists, then try spoofing the MAC address because the possible cause for non connectivity may be the network traffic. Every network interface card (NIC) has a unique MAC Address (Media Access Control address). This applies to all types of network cards, including Ethernet cards and WiFi cards. The MAC Address is a six-byte number or 12-digit hexadecimal number that is used to uniquely identify a host on an Ethernet network.
You can change the Media Access Control (MAC) Address on your network card pretty easily following the steps below.
- Click on Start, then Control Panel, then Network Connections, and right-click on the network connection you want to change the MAC address for and select Properties. It will normally either be Local Area Connection or Wireless Network Connection. If you are using Windows Vista, you have to go to Control Panel, then Network and Internet, then Network and Sharing Center, and then Manage Network Connections
- On the General tab, click the Configure button
- Now click on the Advanced tab and click on the Locally Administered Address property or the Network Address property. By default, the “Not Present” value is selected. Go ahead and click on the Value radio button and enter in a new MAC address. The MAC address is a combination of 6 pairs of numbers and characters. To determine the MAC address, follow the steps below.
- Click on Start and then click Run. In the text box, type in CMD. Click OK.
- In the DOS window (the black box), type in the following ipconfig /all and press Enter.
The MAC address is usually the last item in the list for each adapter and it’s called Phyical Address. You’ll see a set of pairs of numbers separated by colons or hyphens, i.e. 00-E0-4C-05-1C-7C. This is your MAC address for that particular adapter. Now enter the MAC address without the dashes. You can check that the MAC address has been changed by going to the command prompt and typing in ipconfig /all. Restart the computer in order to make the changes to take effect. This is the simplest way to change your MAC address in Windows. After changing the MAC address you will be able to access to Internet through the wired connection.
