WiFi broken after launching without the case

[warmon]

During the HDD replacement I launched my Mac Mini late 2014 without an aluminium case. WiFi worked for some 15-20 minutes but suddenly stopped. Mac sees all the networks, knows it's strenght, but can not connect. An error telling that I have to come closer to router appears (I was in 2 feet close to strong signal router).

Looks like I damaged some module.

Any advice will be apperetiated.

Thanks for help!

I took off the black plastic cover and pulled a little the black wifi block. And it all worked! The wire is correct, I can only assume that the module was under electrostatic and I took it off ...
