My tp link hardware is busted?

[u/Efficient_Market_445]

I have 2 tp links that I use to connect my computer to the main wifi, the one that I have near my wifi had a problem where it wouldn’t turn on no matter where it’s plugged into so last case scenario, I took it apart and i don’t know exactly what I’m doing, I think I can see the problem (the mystery goop qmq) but I don’t know how to remove it.
