What qualification can i get in I.T. that easily leads to a decent job?

Question

I currently work installing cables for networks

Answer 1

What area in IT?  

If you want to do networking, routing, etc, CCNA (Cisco certification).  CCIE pays more, though.

Comptia A+ is the standard for fixing computers (IT intro), help desk, etc.

Microsoft offers several in MCSE if you want to work on servers and it's good if you want to do any kind of support in enterprise systems (like for major companies).

Answer 2

Since you are working in the networks field, why not try to obtain the CCIE? Though you should note that it's probably gonna be the toughest exam out there and so you will need plenty of preparation.

If you are more into databases you should get an Oracle certification. For security, there are plenty of certifications also like CISSP (but you need 5 years of experience) and CEH.  

A+ is pretty good for entry-level jobs. Less technical would be a project management cert.

Answer 3

Depends what you want to do in IT ? If its general IT support then a good qualification would be an MCE/MSCE.

I don't think any qualification guarantees to lead to a decent job though!
