How to troubleshoot common computer network problems


Information technology (IT) and computer network systems (CNS) are complex and often confusing, which means that mistakes can be made that can cause big problems with your business’s operations. Luckily, there are several common IT and CNS issues that you can troubleshoot in order to quickly fix the problem at hand and prevent similar issues from reoccurring in the future. In this article, I’ll walk you through some of the most common IT and CNS problems, as well as their causes and their respective solutions.


Check your cables and connections

It's always a good idea to check your cables and connections when you're having computer networking problems. The following are some guidelines for checking them:

- Make sure that you have the right cables plugged into the right ports. - If you don't know which cable goes where, consult your device documentation or call the manufacturer. - Be aware of any strange looking wires or loose cables.


Check your router and modem

In order to solve computer networking problems, you need to first check your router and modem. If you have a cable modem, unplug it for about one minute. Plug it back in and see if that fixes the issue. If not, then contact your internet service provider for further assistance. For DSL users, unplug the power cord from the router and wall outlet for about 30 seconds. Plug it back in and see if that solves the problem. Contact your internet service provider if these steps don't work.


Check for loose connections

Systems can go haywire for a variety of reasons. One of the most common causes is loose connections. Computers are sensitive pieces of equipment, and when they're not plugged in tightly enough, the system will start sending out error messages or shut down altogether. To find out if this is the case, check all wires, plugs and cords for any signs of wear and tear or missing components. In some cases, people might have been able to accidentally jostle a cord that was barely hanging on.


Check your antivirus software

Computer networking is a vast and rapidly evolving field. One of the best ways for students and professionals alike to stay on top of all the latest developments is by subscribing to professional newsletters or journals related to the subject. Another important computer networking practice that should be performed routinely is checking your antivirus software. Antivirus software provides protection against malicious software like computer viruses, worms, spyware, and Trojans that can have devastating effects if they are allowed unchecked into the system.


Check your firewall settings

When the information coming in is being blocked by the firewall, it can lead to a multitude of errors. If you have other software running on your computer that has an active firewall, such as anti-virus or an anti-spyware program, it may be blocking incoming connections. To check these settings: 1) Open Windows Control Panel 2) Click on Security 3) Check your firewall settings and make sure they are not blocking anything.


Run a speed test

If you are experiencing a slow internet connection, the first thing you should do is run a speed test. Slow connections can be caused by many factors, including poor wiring, an outdated router or simply too much traffic on your line.


Update your drivers

Many of the most common computer network problems are due to outdated or faulty drivers on your computer. One way to solve this is by updating your drivers. Here's how: 1) Open Device Manager (type Device Manager into the search bar). 2) Find the device you need updated and right-click it. 3) Select Update Driver Software. 4) Choose Search Automatically for Updated Drivers 5) Click Next and wait for your computer to update the driver software.


Check for malware

One of the most common computer network problems is a virus. You may have trouble accessing or running applications, or you might get a notification that your computer is infected.
