Answer 1

Find out the make and model of the lan adapter and download the driver for it. That most likely is the problem. Check device panel and see if your network connections shows up on the list. if you dont see it or it has a yellow triangle caution sign next to it, it doesn't have a driver. also check to see if it is enabled.

Answer 2

If you are not able to connect to internet, then it may be that you have the drivers for LAN card is missing. Most computers have the motherboard CD(assuming you have attached NIC card) or the third-party vendor CD from which you can install the network drivers.



First of all check whether it is attached or on-slot LAN card. If it is attached, you may use the motherboard CD to install the drivers(you may not have installed the chipset, video or audio drivers too). Use the chipset installation and most thing are done by it. If not setup each component manually.



For the on-slot, insert your CD and run setup.



Checking the driver

-----------------------------------

1. Right-click the My computer icon on desktop and select properties.

2. On left side, select Device Manager.

3. Open Network Adapters node and check if the device is shown or not. If the device is there, then you have the driver installed already.

4. If the Network adapter is not shown, run the program from CD.

5. Check the Other Devices node and make sure that the Network Controller is not there. If it is there, update the driver and show the location to the CD when asked.

6. Close the Device Manager and Log off or restart the computer.



Note: Use CD or automated programs whenever possible to save out from the trouble.

Answer 3

Check the IP address on your computer. You can open a Command window by going to Run and typing in "cmd". It will open the DOS window. Type "ipconfig". This will give the address of the card. If it begins with 169.254.X.X then you are not getting an address from the router (assuming you have a router). If you don't have a router, then it is safe to assume that the addresses have been taken up by the other two PCs. If you have a router and the other two PCs are working, then try changing the connection to a different port. To test if the router port is bad connect your PC to a port that is connected to one of the other computers. If your system doesn't work, it is either the cable or the network card.

Answer 4

You probably need the network drivers installed. They would be on the disc you got with the motherboard you installed. If not get them form the mobo manufacturer's website and install them.

They may also be called system or chipset drivers.
