iPhone 6/6 Plus WIFI Module Fault Repair

Have you ever met the same weak WiFi signal or no WiFi signal situation on iPhone 6 or 6 Plus? In this article, we'll tell you how to fix the problem:

1. iPhone No WIFI

Carefully disassemble the iPhone by phone opening tools, remove the iPhone motherboard and check it, there are no obviously scars. Measure the C5202_RF with Fluke 15B+ Digital Multimeter to check whether there is 3.8V voltage, if not, use hot air gun to weld a jump wire from other side to C5202_RF. Measure the C5204_RF to check whether there is 1.8V, if not, make a short connection on R5208_RF.

Check and replace L5201_RF, C5201_RF, replace iPhone module IC.

2. iPhone Weak WIFI Signal

If the iPhone 6 or iPhone 6 Plus can connect with WIFI, but the wifi signal is weak, we need to check iPhone wifi antenna first. You can fix it by replacing filter FL5201_RF, and replace iPhone WIFI module.

NOTE:

1. If the iPhone suffers from water or falling damage, the PP_VCC_MAIN voltage it easy to disconnection and it cannot be reached to WIFI. In this case, you can weld the jump wire from other place to capacitor C5202_RF.

2. The resistance R5208_RF is easy to corrode after water damaged and then cause no WIFI issue. In this case, you can short connect it.

3. Damaged capacitor C5201_RF and inductance L5201 can cause no WIFI and auto reboot failure, just fix WIFI and then auto reboot error will be solved. More iPhone repair technical support you want to get, just visit on www.vipfixphone.com
