No Wifi Hardware installed, but bluetooth works

I've been having this problem for some time, and i recently found a ray of hope ( I think).

So my wifi card was giving me problems before after a fall from my MBP. Then, the display got dislodged from the upper casing, but my wifi was working just okay. Progressively, the wifi started getting spotty and i'd have to close and open the lid twice or thrice to get it started again, and finally one day - "No Wifi hardware installed".

Now, i managed to recently stick the display back in after getting rid of a ding on the side.

Weirdly, the bluetooth starts working now. Am i hoping for too much to expect my wifi to start working again?
