any of the problems associated with wired networks have been largely overcome with the introduction of more efficient and maintainable wireless networks. Here are some network troubleshooting tips for a few of the more common problems that you might experience.

omputer networks are designed to move packets of data from one device to another. When there is a problem with communication it calls for a little network troubleshooting. Before calling in network support in the shape of a computer network consultant, there are a few things that you can do yourself. The first thing to do is to resolve why communication has broken down and see if there is a simple solution. The two most common reasons for data not moving correctly or not moving at all are:

  • Due to a physical break such as an unplugged or broken cable and/or
  • Because one of the devices on the network is not working correctly.

If just one workstation is experiencing a problem connecting with other devices, then the problem is probably either its network cable or network card – check the cable connections at the workstation and the router. Try plugging the cable from another workstation into the faulty workstation socket – if the connection works then the fault is either the cable itself or the faulty workstation’s network card. Check to see if the LED light is working. Try rebooting the workstation and if necessary exchange the faulty network card for a good one.

If multiple workstations are having a problem connecting to the fileserver or another device such as a network printer, it is not likely to be a cabling problem. If this happens try rebooting the router. If there is still a problem, reboot the fileserver or the network card on the printer. Always keep in mind that you can test a connection between two network devices, providing you know their IP address or network name, by using a “ping” command.

f multiple users are having problems connecting to your wireless network but there are still some users who can connect, it is most likely that the network has several access points and that one of them is not working correctly. It is often possible to work out which one by looking at the physical positions of the users who are having a problem and seeing which access point serves that part of the building.

If none of your users can connect there could be several reasons. If there is only one access point then it could be faulty or there could be a configuration error. The problem could also be caused by radio interference. Try pinging the access point – if the ping is successful then the fault lies beyond the access point. Try pinging from both sides of the access point – if they both fail then the access point itself is at fault.

These are a few network troubleshooting tips to help you to try to sort out network problems before having to call in your computer networking service.
