I've tried anything wrote in the link but doesn't work. I think is a hardware issue. I still did not understand where the wi-fi chip is. I woul try a reflow in the case...Leave a comment:

The wifi cable looks fine to me. The phone has no liquid damage. Do you know where the wifi chip is located? If it is a BGA, like I think, must be visible on the board...Leave a comment:

I tried to hard reset but the problem Is still here, so I suppose it's and hardware problem.
So the problem could be the flat cable (te he G990U_FRC_R02?) or the commectors of It in the 2 board?
Both the flat' connectors and the mobo's connectors seam fine to me...Leave a comment:

Samsung S21 FE wifi not working
Hi everyone, I have a Samsung S21 FE with no wifi. I can't see the classic antenna cable so i suppose it is integrated in the circuit of the mobo. Can anyone help me with this?
I have very good skills in soldering and stuffs.

I test each led individually and each works fine. Now I don't understand.. can the problem be the two components at the extremity of the section that doesn't not work?
