Here is a good video on this model:

The wifi cable should look like this:

Was this unit water damaged? It is possible that the BGA balls are corroded if there was liquid damage to the phone and the WIFI module is not visible to the logic board.

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

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.
