Sony Xperia XZ2 dual H8296 does not detect wireless network

Hello friends, good afternoon, how are you? I decided to write to them because I am having a problem with my Xperia XZ2 Dual device (H8296). The particular problem with the equipment is that I cannot move forward while trying to connect the wireless network in the initial configuration. The device was working normally until from one moment to another it stopped detecting the sim card (I tried with other sim cards in my computer and they don't work I tried mine on another phone and they work). Due to this problem I decided to repair the equipment with the Xperia Companion software to the latest version and the process was carried out without problems, but at the time of turning on the equipment and starting the configuration; it reaches the wireless network configuration part and looks for networks without being able to find any. Even if I manually add the network it does not detect that of my home. I have already tried several networks but I still don't succeed. Another problem that makes me in some moments, not always, is that when searching for networks the phone restarts without reason and returns only to turn on but always remaining in this configuration step. As this method did not work, I decided to apply another previous firmware and do it with the Flashtool program but the same thing happens to me, it remains in the initial configuration without connecting to a wireless network. I would like to know if someone had the same thing with a similar model. I don't know how to interpret the problem. If it is a firmware problem ... Why with two different problems does the problem continue? Could it be a problem with the wireless adapter that does not detect networks? ; If so, why does it restart? Will it be a battery problem? but ... why don't you take a wireless signal? Could it be that the android system is generating a problem? but that should at least let me take a signal in that case. Since I thank you for your comments with input to understand and solve my problem. Thank you very much, friends.

Thanks for your response Javier !! I ask you another question, if it is a hardware problem, what could it be? Do you have an idea of a similar problem? Thanks for your help.

That is more complex friend ... due to the compactness of the board and in the absence of a diagram of the Wi-Fi section of the board to check components ... sometimes by some blow some component is detached from the board or a flex out of place or excess of dirt in the circuits but sometimes it implies change of plate so if it does not work with the original software or with the latest version it is already an internal problem in the board

You have to check the wifi antenna that is surely failing!
