iPhone x wifi not working

Hi iPhone x problem. firmware goes ok to iphone, no errors. The display is also broken. does not take any contact or very slow contact. I have not yet received new touch screen, but I think it solves the touch problem. the most important thing is the wifi problem. no wifi. 3utools can't read wifi data or serial number? the phone has fallen to the floor and then it has stopped working. what do you need to check on the wi-fi in the circuit diagram?
