Can you provide detailed pictures of your switch? Also as Matt suggested have you tried to undo what you have done?
Might I suggest you get some desoldering braiding and some flux.. Dip the braiding in the flux so that some of the flux is on the braiding (not too much). Then cover your joints with the flux dipped braiding and apply your iron to the top of the braiding.... That will suck up all the solder..
I doubt you fired your Wifi board but you never know... also what wattage iron are you using?
