讀不讀計算機信息管理業不重要,重要的是有一門找工作的技術

If you already have a degree, you do not need waste $$ and 4 yrs time to get another useless degree.
Since you already knew IT Network stuff, you are pretty cool.
You will find job based on your skill.
Skill can be learned without go to college or university.
As long as you knew the skill, knew how to do interview, you get the job.

Thanks!
