Chosen Solution
Hey, I have an iphone 8 plus that has wifi grayed out, but will still connect to cellular. Any ideas? I have already reset it entirely and it still didn’t work.
Broken wifi chip which requires board level repair, that’s it. Wifi and cellular are unrelated.
That sounds like WI-FI chip is damaged or dry soldered.There have two factor that you can solve by this way. Sometime WI-FI chip dry soldered throw over heat that remove PCB from board and re-hot WI-FI chip on 240 aprox 1 min then check most of the cases are solved.If the problem is still same remove the WI-FI chip then re-ball and fix. If you have to change the WI-FI chip that need to unbind the Nand chip too.So,you need the Nand programmer to unbind WI-FI address or WI-FI address unlocked.If you have to know further this may help you.Have all process 7,7Plus and 8,8Plus have same process.
Sounds like you are having issues with your wifi antenna. Your in good luck it’s really cheap. iPhone 8 Plus Wi-Fi Diversity Antenna
Can confirm it is board related. Have ran into this issue and it was still occurring after replacing all antennas.
