Hello everyone, I replaced the screen recently after cracking it while leaning against a metal railing. I don’t recall the problem started after the cracking or after the screen replacement, but the wifi doesn’t not work and the wifi option is grayed out. Troubleshooting I have done:

  1. Replaced both the antenna chip and the logic board flex cable.
  2. Reset network settings The problem persists. Is there anything else I can do outside of taking it in to an Apple Store or a 3rd party technician to repair the logic board?

It is very possible that you damaged a component on the logic board when you leaned against it. My guess is it would be the logic board because you have replaced the antenna chip and flex cable with no success. iPhone 6 Logic Board iPhone 6 Logic Board Replacement
