iPhone 6 WIFI button is grayed out, how to fix?

The iPHONE 6 WIFI button is grayed out, which means iPhone 6 WIFI cannot be used, it's important to know how to fix it.

According to our experience, the WIFI grayed out issue mostly caused by  iPhone 6 WIFI module IC not working.

Disassemble the iPhone 6, take off the iPhone 6 motherboard. Test whether the main power supply 4.2V has been delivered on C5202_RF, if not, it can be supplied from any place with main power supply, or directly replace WIFI module.


Before disassembly, we need to do some protection to avoid blowing other chips. The WIFI module is surrounded by glue. We must first preheat and remove the glue, and pay attention to small components, especially small resistors. you must to solder it again if some of the components are lost.

The WIFI module on line is relatively thin, do not use solder iron back and forth on iPhone solder pad, testing resistance again after cleaning.

As shown in figure 14-5-3, the lower right-hand corner is easy to break, and the normal is infinite. Therefore, it is necessary to measure whether it is connected to the external connecting elements, if not, it's necessary to solder jumper wire.


There are two kinds of WIFI modules in the market: high temperature and low temperature. We use low temperature and control at about 240 degrees, then install to test the iPhone device. First use the DC power supply to add electricity, Generally if IC involved in the main power supply circuit, do not directly use the battery to boot after replacing IC as to avoid the motherboard burning.

Finally, install the iPhone 6 well and then get into IOS to test, now the iPhone 6 WIFI button can be turned on, the WIFI can be used smoothly.
