3 Common Network Problems and How to Solve Them

A computer network is a highly complex technological system that can fail or malfunction for a number of software or hardware-related reasons. Troubleshooting a network issue is never easy, and the constant calls and emails from disgruntled clients and coworkers who need the problem to be solved ASAP don’t make it any easier. 

In order to help you resolve your issue in a timely manner, we have compiled a list of the most common network malfunctions and provided a brief explanation on how to solve them. If troubleshooting network-related issues isn’t your forte and you’d rather let the experts deal with it, click here to get in touch with a professional IT service. 

The most common network problems include:

Virus infections

Computer viruses can come from a variety of different sources, including shady websites, email attachments, malicious software, and even social media. Network viruses can disable entire networks, corrupt data, and lead to severe financial losses. 

Here’s how to deal with most network viruses:

  • Step #1: Perform a full network scan using quality anti-malware and anti-virus software. Make sure to scan root directories, hidden files, any running programs, and your email inbox.
  • Step #2: Safeguard against data loss and network instability by performing a complete system backup. 
  • Step #3: Quarantine or delete all irregular or suspicious files to keep them from infecting the rest of the network. Delete any infected emails. If these emails arrived from someone you know, warn them that their network is compromised.

No internet connectivity

Being unable to connect to the internet on one or multiple computers in a network is a serious hassle that can cause considerable damage to a business. To make matters worse, it’s often difficult to solve without professional-level knowledge and tools.  

Try the following:

  • Step #1: Check for hardware problems. Your router may be turned off or unplugged from the wall, or the network cables may be damaged or not plugged incorrectly. 
  • Step #2: If a computer or a device can’t wirelessly connect to the internet, try putting it right next to the router. If that works, it likely means there’s a hardware issue. 
  • Step #3: Update the network card drivers. If this doesn’t help, you’ll need to contact your IT department. 

Slow performance

There’s nothing worse than having to do sensitive work on a sluggish computer. Unfortunately, there are many reasons why a computer may be working slowly, stuttering, or encountering other problems that make it difficult for your employees to perform their designated tasks.

These reasons include:

  • Outdated hardware. If you haven’t upgraded your systems in a while, your computers may simply be too old to effectively deal with modern workloads. Contact your IT department and have them propose cost-effective upgrades. 
  • Heavy bandwidth usage. Your employees may be trying to download too many large files or stream too much digital content. This can overload your network, causing it to slow down dramatically. Your best course of action is to upgrade your network to meet your company’s needs.
  • Clogged operating systems. Browser extensions, applications running in the background, or bugged software can all take up a huge chunk of your processing power. Fire up the Activity Monitor (for Mac) or the Task Manager (for Windows) and try to figure out which applications are overutilizing your computer’s resources. 

In conclusion

Unlike many other IT-related issues, a malfunctioning network often affects an entire business and may even prevent it from operating until it’s dealt with. Unless you have a background in IT, your best course of action is to have the problem looked at by certified IT experts.
