Learn about the most important Computer Network Technician skills, how you can utilize them in the workplace, and what to list on your resume.

Computer network technicians are responsible for installing, configuring and maintaining computer networks. They use a variety of skills to troubleshoot problems and keep networks running smoothly. If you’re interested in a career as a computer network technician, it’s important to understand the skills that are necessary for the job.


WAN stands for wide area network, which is a system of computers that are connected over long distances. A computer network technician needs to understand how WANs work and the different types of connections they can use. For example, you may need to know how to configure an internet protocol address or how to set up a virtual private network.

Attention to Detail

Attention to detail is the ability to notice small details and make precise adjustments. Computer network technicians use attention to detail when troubleshooting computer systems, as they must identify the source of an issue accurately in order to repair it effectively. This skill also helps them document their work thoroughly so that other technicians can understand what steps they took to fix a problem.


Firewalls are software programs that protect a computer network from outside threats. They can block malicious files, hackers and viruses from entering the system. Firewalls also monitor incoming data to ensure it’s safe before allowing it into the network. Computer network technicians use firewalls to secure their clients’ systems.

Analytical Skills

Analytical skills are the ability to examine a situation and determine the best course of action. Computer network technicians use their analytical skills when troubleshooting computer systems, as they need to analyze what’s causing an issue and find the solution. They also use these skills when determining which tools or equipment they need for a job.


Switches are the devices that allow computers to communicate with each other. They can be either physical or virtual, and they direct data from one computer to another. Computer network technicians use switches when building a computer network or troubleshooting an existing system. Knowing how to install and configure them is essential for this job.


A knowledge of local area network systems is essential for computer technicians, as they often install and repair these types of networks. A strong understanding of how to build a LAN can help you advance in your career because it allows you to troubleshoot issues with the system and make necessary changes. You may also need to train others on how to use a LAN, so knowing about them can be beneficial for any type of job in this field.


Communication is the ability to convey information in a way that others can understand. As a computer network technician, you may need to communicate with clients and colleagues through email or phone calls. You also need to be able to explain technical concepts in ways that non-technical people can understand. This skill can help you work more efficiently and build stronger relationships at work and in your personal life.

OSI Model

The OSI model is a standard for networking protocols. It’s important for computer network technicians to understand the different layers of this model and how they interact with each other. This knowledge allows them to troubleshoot issues more efficiently, as they can identify where the problem may be occurring in the system.


TCP/IP is a set of protocols that allow computers to communicate with each other over the internet. TCP/IP includes two main protocols: Transmission Control Protocol (TCP) and Internet Protocol (IP). TCP allows computers to send data, while IP identifies where the data should go. Having knowledge of TCP/IP can help you troubleshoot network issues and configure routers and switches.


Cabling is the process of installing and connecting network wires to various devices. This includes running cables through walls, ceilings and floors and attaching them to routers, switches, computers and other hardware. It’s important for computer network technicians to have strong cabling skills so they can install and configure networks properly. They may also need to troubleshoot issues with existing cabling systems.


VPN, or virtual private network, is a technology that allows you to access the internet through an encrypted channel. This can be useful when working with sensitive data because it prevents others from accessing your information. VPNs are also used for remote connections and telecommuting, which means they allow you to work remotely by connecting to your employer’s computer system over the internet.

Customer Service

Customer service skills are important for computer network technicians because they often work with clients to determine their needs and find solutions. They also interact with clients when installing or repairing computers, so customer service skills can help them communicate effectively with customers and provide quality service. Customer service skills include active listening, empathy, patience and the ability to remain calm in stressful situations.


Troubleshooting is the ability to identify and solve problems. As a computer network technician, you might troubleshoot issues with hardware or software. For example, if a user reports that their computer isn’t working properly, you might examine it and find out what’s causing the problem. Then you can fix the issue by updating the device’s operating system or reinstalling its programs.


Routers are the devices that allow computers to communicate with each other. They direct data from one computer to another and help connect multiple systems together. Routers can be hardware or software, depending on the type of network you’re working with. Computer network technicians need to know how routers work so they can install them correctly and troubleshoot any issues that may arise.


Ethernet is a protocol that allows computers to communicate with each other. It’s the most common method of connecting devices in a network, so it’s important for computer network technicians to understand how Ethernet works and be able to install and troubleshoot it. They also need to know how to connect different types of equipment to an Ethernet network, including routers, switches and firewalls.


Organization is the ability to keep track of files, documents and other information. As a computer network technician, you may need to organize your work area so that you can find tools quickly or remember what steps you took when troubleshooting a problem. You also might use organizational skills when creating diagrams for documentation purposes.

How Can I Learn These Computer Network Technician Skills?

There are a few ways that you can learn the skills that are necessary to be a computer network technician. One way is to take classes at a local community college or online that will teach you the basics of networking. You can also find many books at your local library that can help you learn about networking. Finally, there are many websites that offer free tutorials on networking concepts.
