Experienced network engineers are in high demand these days, and working as a freelancer means you can work from home and offer your services to businesses in different cities - or even different countries.

Your responsibilities will be the same as a freelance network engineer as they are when you work for one business directly, but communicating with your clients will become even more important.

Additionally, a freelance network engineer will need to be comfortable working long, irregular hours, and even some weekends. Network engineers can be on call for 24 hours a day if something goes wrong, so you need to be prepared for that circumstance when you take on a bigger client.
