WIFI only works when I am pretty close to the router

[AC Question]

So my phone fell onto the ground by an accident, the screen broke and I went to a local [not a very trusted] shop to replace the screen. After fixing it and returning home, I found out that my WIFI only works when I am pretty close to the router and that's pissing me off.

Do you think that this might have been due to the fall? or did that shop replace some high copy **** into my phone and stole my original parts? can you please help me?

More likely that a wire got dislodged or the antenna damaged by the person replacing the screen, or the fall itself. You might want to take it to a proper phone tech for a look. Of course that's after you have tried the reboot/cache partition wipe stuff first (although i doubt it's a software issue)...
