iPhone 4 – No WiFi Hardware Problem (Greyed out)

This is a very sad time. My iPhone was submerged underwater when I went Kayaking. I disassembled the iPhone and reassembled (see prior post). I thought all was well until I just now realized that my WiFi is not working. I get a grayed out option as if my iPhone isn’t equipped with a wireless device. I’m sure by now you have heard of the “Chill” Method or reset your network settings, but if you dropped yours in water, more than likely this will not fix the problem.

Ive tried both to remedy the issue and no luck. What I have done is purchase a new antenna for your iPhone and I will reinstall it. I’ll post with my luck on this adventure once I get the part. I really do not want to bring my phone into AppleCare only because I just dont want to re-up my firmware and deal with the issue of retweaking the phone the way i want it. Besides………. iPHONE 5 is coming out in September.

I noticed that I had the screws not correctly placed. In fact the “yellow” screw was initially not in the iPhone when I reassembled it. After replacing the Wifi Antenna with no luck, I purchased a screw set off ebay for 2.50 and replaced all the screws. We are back in business.

    Exactly the same with my iPhone – please post how you get on, I’m hoping it’s the antenna and not the motherboard, as everything else is OK

    I replaced the antenna for the iPhone which you could find on ebay cheap. This didnt fix the problem.

    The solution was that all screws in the cover plates and iPhone NEED to be placed in their respective locations. I believe there is continuity that runs through the iPhone to achieve signal strength and to complete circuits. When I reopened the iPhone I noticed that the iPhone was missing a screw in the bottom of the upper metal backplate. When I placed a screw in there and ensured contact on the base of the LCD screen. My wifi appeared.

    I guess I would say that make sure that all connections are clean. and each screw in its location is the correct screw. I totally underestimated this. Wifi shows now, however my service is intermittent or low.

    Did this work? I somehow think it won’t since the water has probably damaged the actual logic board and/or WiFi chip which is damaged. The same thing has happened to me, and I’m desperately trying to look for a fix. Weird how it get’s grayed out though…

    Same thing here, my son dropped it in a sink full of water, it dried out, everything works perfectly except the Wifi which is greyed out.

    Don’t know if I trust myself to open it up and try stuff, but to the OP, do you think you fixed the problem by replacing antenna AND reseating the screws, or do you think just fixing the screws alone did it?

    I don’t have AppleCare on this phone, does anyone know a ballpark figure of what Apple charges for these kinds of repairs?
