Sony Vaio wireless switch problem

Hello,
I just recently put a new power jack in my laptop.
Everything worked fine except for now my wireless does not work.
I have a Dell Latitude D620 laptop. I keep getting an error that says the radio is disabled.
I try to enable it and it does not save the setting. It reverts back to disabled.
The FN - F2 keys do not turn the wireless on. It does nothing.
The wireless switch on the side seems to be very loose and the LED does not light up.
I've went into the wireless utility to enable it and I still get the error that says it is disabled.
It is recognized in my device manager and it says it is working properly.

I'm game for taking the whole thing apart again....I just don't know what to do from this point.

Any guesses would be great.
I don't have the money to send it back to Dell and, of course, the warranty has expired.

Thanks,
Kimberly
