Chosen Solution
Following a screen replacement, my iPhone 7 has greyed-out the option to connect to Wi-Fi. What would be the best path to resolution, as I’m not at all sure what to do?
It is hard to see how the Wi-Fi can become greyed out after a screen replacement. If the screen was replaced due to a drop it has probably damaged the Wi-Fi chip. The chip would have to be removed and reballed. This would be an expansive repair.
