1. Learning basics: First of all, you need to master the basic knowledge of computer networks, including network topology, protocols, IP addresses, etc. You can learn by reading related books, taking online courses or watching teaching videos.

2. Practical operation: theoretical knowledge is only the foundation, and practical operation is the key. By building your own network environment, network configuration, troubleshooting and other practical operations, you can deepen your understanding and application ability of network engineering.

3. Participate in the project: Participating in the actual network engineering project can help you better understand the work content and requirements of network engineers. You can try to join open source projects or volunteer organizations and cooperate with others to complete network engineering projects.

4. Continuous learning: Network engineering is a constantly developing and updating field, so you need to keep the attitude of continuous learning. You can pay attention to industry trends, participate in relevant training and seminars, and constantly update your knowledge and skills.

5. Get certified: The certification of network engineer can prove your professional ability and knowledge level. You can choose some authoritative certification exams, such as CCNA and CCNP. , and obtain the corresponding certification through the examination.

In short, self-taught network engineers need to study and practice persistently, while maintaining their sensitivity to new technologies and enthusiasm for learning. By accumulating experience and improving your ability, you will certainly become an excellent network engineer.
