Wifi gone, wires broken

Hello, I have a Vivobook S400C that is pretty similar to the S55. My wifi is completely gone and says it can't connect to any networks at all when I had dropped my laptop pretty badly. I opened it up and saw the 2 black and white wires that I believe are for wifi have been unattached! I tried putting them back in but the tips are a bit damaged. Everything else on my laptop works fine. What should I do?
