Cause: This type incident may occur in each and every network environment. There are different ways it may happen. Given below is the some of the areas if any short may occurs then your network may not work.

Network card not connected properly

Bad NIC card drive's settings

Bad network hardware

Problem with switch

Problem with router


First of all verify that the both end of network cables properly connected t, one end to the NIC card, which is plugged into the computer and one another end which is connected to switch. Ensure that the green light is blinking on the NIC, this shows that the NIC is either receiving or sending the data. if the card does not shows any lights or has orange or red lights, it means problem happened in the NIC card. To resolve that problem you may have to check whether it was fixed correctly. If it is done and still not working you may have to remove NIC card and have to fix a new card.

Ensure that the network switch is power on and cables are fixed properly. If it is done, make sure that the router is power on and cables are connected properly. If it is in correct way, but still it is not working so you have check the configuration setting of the router, it might be exist if the configuration of the router setting is changed.

A printer connected to the network does not print

Cause: A problem might be with the physical printer, the logical printer setting on the client computer, the application you are trying to print from, network protocols, or hardware.

Solution: Try the following to isolate and solve the problem:

Make sure basic network connectivity. Check user rights, protocols, share names, to determine whether you can see the server. Try to copy a file to the server; if you unable ro access the server, you may not be able to access the printer.

Create a local printer and redirect the port to the network server. By using Add Printer Wizard, click Local, and then type the server and printer name for the printer (\\servername\printername). This make sure whether you can copy files from the print server.

Make sure the physical printer is on. If other users can print, it is probably not a problem with the printer, or with the print server.

Make sure that the printer on the print server is using the proper printer driver. If print clients are using other operating systems, verify that you installed all necessary drivers for the other platforms.

Make sure the print server is operational, make sure there is enough disk space for spooling, and make sure the print spool service is operation.

If print clients are using operating systems except Windows XP , verify the client computer has the proper printer driver.

Verify the physical printer and make sure it is in the ready status or ready to print. To verify correct operation you can print a test page from the printer console itself.

Check the cable connected to the printer is connected properly. check the light on the card, which indicates network connectivity, If the printer is connected directly to the network with a network adapter,

Make sure you can communicate with the printer over the network. To verify you can use the ping command, if a printer communicates over the TCP/IP protocol.

Make sure the print server is working by using other computers.

Verify the print server ,print spool service is operation on

Network adapter is unplugged

Cause: If your machine shows that your network adapter is unplugged, it might be happen because of quite a lot of different problems.

Eg: loose connection, connection disabled


Make sure that both ends of the network cable are properly connected. If the cable is properly connected, verify that your modem and router are plugged in and turned on.

If you have only one network port available in your router, plug the cable into a different port. If the network connection works, the original port on your router is faulty. However, you can continue to use the other ports.

Replace the network cable with a new cable. It might be a problem with network cable.

Ensure that the network adapter on your computer is working. To verify, connect a different computer to the same network cable. If the connection works, the problem is with your network adapter. Replace it.

Wireless Connectivity Problems

Cause: The most common problem you'll encounter with wireless is connectivity; it might be happen because of several different problems.

Eg: limited connectivity, wireless adaptor problem etc…..
