Actually, the WiFi antenna does not have a spring-like connector in the bezel. The antenna is just a small, oblong strip of gold (or gold-plated metal) with green insulation. This antenna is located in the top plastic panel (the removable panel that houses the holes for the SD slot, the headphones and the power switch), just below the SD slot. Probably you accidentally bent this strip and now it fails to make contact with the mainboard. Try straightening this strip, and if needed, glue it with a drop of super glue to the panel, but make sure you don't spill any glue on the contact area (exposed metal), else you'll prevent good electrical contact. Also, check the corresponding place in the mainboard (opposite side of the SD slot), there you will find a small golden spring contact. Try to stretch it a little bit to make sure it contacts the antenna.

I think the spring-like clip you're seeing is the one that holds the stylus in place. It's the only spring-like device in the TX's bezel.
