When you dropped it, you might have disconnected the WiFi antenna cable. You will have to open the casing to reveal the entire motherboard and on the rear side top left corner, there should be a black antenna cable that is unplugged. Just plug it back in by pushing it down into the port. If that is not the case, then you will have to replace the whole motherboard. Check with the Kindle Touch troubleshooting guide for options.
