Networking and HR are very different fields.
You used to work in IT - did you like it? Did you like the technical side of it? If so, maybe networking would be a good fit for you.
On the other hand, people who work in HR have to deal with a wide range of topics, like safety regulations, evaluating what insurance policy would be best for the company, making sure the company follows employment law, etc. It helps to have good people skills, too. Does that sound like a better fit for you?
