WiFi stopped working - option greyed out

Thanks for the prompt response.

Should have mentioned in the original post, that there’s no WiFi MAC address displaying in the about section. (I guess that confirms the WiFi chip is kaput?)

I wasn’t sure if the logic board was linked with the touchID - is the screen linked to touchID?

Touch ID is paired with the logic board. The screen is not paired to anything.

Thanks for that.

Say I wanted a technical challenge, and really wanted to try the exercise of swapping out the logic board. I assume the procedure is then to swap both logic board and TouchID - will that work, or is there any inbuilt protections that would prevent that? (I.e something restricted to authorised repairers)

I assumed they were mutually linked at the factory, if you swap logic board without touchID then you’re stuck with pin entry, right?

Thanks for the follow up answers

Yes, the procedure when doing logic board swaps is to keep the same home button with the same logic board to retain touch ID functionality.

Otherwise if another home button was used instead of the original one that came with the logic board you'll be stuck with pin entry and basic home button functionality.

Lovely stuff, thanks Ben for the confirmation!
