Greyed out Wi-Fi is defiantly a problem with the Wi-Fi chip or the big audio IC. On a working phone you can remove all the Wi-Fi antennas and it still will not be greyed out so you can rule out antenna problem. If you don’t want to get it repaired you could try and put a thin piece of packing under the Wi-Fi chip so it has a little more pressure on it. Sometimes this can get a couple of month’s usage before it completely fails.
