Chosen Solution
My Iphone 7 constantly connects and disconnects to the wifi internet, for each 10 seconds connected I am 10 seconds disconnected (My 4G internet, celular signal to make calls, and my bluetooth are working normally and well) If I were to replace the wifi antenna I dont understand if I need to replace the “ Top Right Antenna“ or the “Wi-Fi Diversity Antenna” , or both? Which part needs replacement?
Would try both
these are the parts I found available
