You're probably not orienting the antenna correctly or it's wired in wrong. Go to iFixit: The free repair manual and look at their instructions for replacing the antenna.

I did all the correct step

Then it's pooched in some other way. Sounds like you'll be in the market for a refurb'd iPad (and a more shockproof case for it).
