Advancing career, just curious if what I have going is about the average?

I am an IT Assistant for a corporate company that owns a bunch of newspapers I make good enough pay to support me and my wife and have enough money to put back for savings. But just curious if I could have potential for more pay? I make $17/hr and I’m going on my 3rd year of total IT experience. I have my associates degree, only look to get my bachelors if the company pays for it. Don’t want anymore debt than I already have. I have one certificate but it isn’t well known, mainly I am curious what could I look for down the road? Is what I am getting acceptable?
