I broke a little piece of the Logic Board, near the 4,8mm Philips Screw, and since that moment my Wifi connection has become terrible, i had to be near the wireless router in order to get connected.
I tried to change the EMI shield, but with no success.
Could that little gold piece have damaged the wifi reception ?
Is this fixable ?
Thank you very much for the support.
Is this a good question?

Andrea, yes it could be a big issue. That "little gold piece" is part of your "ANTENNA MATCH AND FEED" circuitry. It is reference designator SP2_RF and check the attached schematic. The only way to fix it would be to somehow get a contact point to connect to the logic board and the opposite mating area.

Basically if you have an absorption problem is related to wifi antenna is in black and at its end there is a connection silver color.
You can easily recognize it, what keeps the silver connector, it is the longest screw in the black antenna (looks like a black Plata is also pressuring the connection screen) and a long screw that holds the silver connection is very small, he may have fallen or have not closed the screw hard enough.

HI, thank you for your reply, I just submitted the image where there is the broken horn.
I do have the EMI shield with the silver connection, i replaced it twice and I didn't solve the problem.
