WiFi Greyed out iOS 6.1.3

"I've seen this issue quite a bit.

It's definitely not software related, but hardware related.

What you need to do is:

1) remove the back glass and unplug the battery and remove it.

2) Remove the Emi shield that covers the LCD connector

3) inspect the board and you will see a black big chip (the wifi IC). Looking straight down with the charging pins closer to you, it'll be on the right next to the LCD connector.

4) THE FIX - you need a hot air type of tool. I'm not sure if a hair dryer will do the trick, but I use a heat gun. You need to apply slight amount of heat. NOT a lot. Just enough to get it hot but not too hot (too hot = you can't touch) like I said, slight heat.

5) put the phone back together and voila. Works!

I've seen roughly 3 phones already same issue same fix. No warranties so far."

"I can confirm that YoloRepair's fix does work. I did it on my phone today that had the greyed out Wifi issue. I want to add and clarify a few things that might help the next person:

Watch this video before doing anything: http://youtu.be/ZHH-zbNgJx0 You don't need to follow all the steps, just the ones on how to open the phone, disconnect the battery, and remove the EMI Shield. That's all you need to do to disassemble. You will need a pentalobe screwdriver to open the phone and a spudger definitely helps with prying and whatnot. You can buy them both of course on iFixit.

I disassembled and using a hot air station, put hot air on the wifi chip and heated the surface to almost 400 deg F. I used a heat sensor to read the temperature as I was heating it up. It only took maybe 5 seconds. I would strongly recommend this method over a heat gun as the air temp is easier to control and put down on the chip. You don't want to heat anywhere else, and you don't want to overheat and potentially blow the chip or other components off the board. That is it; i reassembled and wifi turned on and has stayed on and has stayed connected thus far."

do a hard reset, just hold the "Sleep/Wake" button on the upper right of your iPad along with the circular "Home" button on the lower middle part of the device's bezel. After 10 seconds, you should see the Apple logo. That's the sign that you've successfully pulled off a hard reset with your iPad.

I did the freezer thing and it worked for me. I left mine in the freezer for about 15 mins (have the phone turned off) then after the 15 mins I turned it back on and did a reset network settings straight away. I did this a day and a half ago and I still have my wifi.

Freezer thing is temp fix. i tried it .. first it worked for a day. then it lasts only for 15-30 min... so then i took it to service shop. they opened it and then heated the wifi module with blower. he said this is very common and the fix works as permanent. if incase even this fails, need to to replace the wifi module chip which costs $60. for the the hot blower thing works.. its been and day and its steady.
