iPhone 6 Plus's WIFI signal is very poor, how to do it?

Our customer sent us an iPhone 6 Plus. This iPhone 6 Plus can open the WIFI icon, but the WIFI signal is very bad. If the iPhone is a little far from the router, it has no signal at all. How to solve this iPhone WIFI problem? The following is the solution, you can refer to it.




First, open the iPhone and test it. Open the WIFI icon to search for the WIFI address, the WIFI address that can be searched is very small, and the signal is very poor, but the iPhone with good conditions can search for multiple WIFI addresses, which means that the iPhone 6 Plus is abnormal.

Use phone opening tools to disassemble the iPhone, first we need to check the iPhone WIFI IC. In order to test whether the iPhone WIFI IC works normally, we can solder a jumper wire to replace the antenna circuit on the periphery of iPhone WIFI chip.

Check iPhone schematic diagram via WUXINJI Dongle, we can solder a jumper wire as the antenna from C5213_FR than next to WIFI.




After soldering the jumper wire, power on iPhone and test it, now there are many WIFI address can be searched, and the iPhone signal is normal.

According to our repair experience, the iPhone WIFI signal back to normal after soldering the fake antenna is because of the iPhone WIFI signal filter FL_CELL_WIF_RF is damaged. Usually, we can fix it by removing the iPhone WIFI signal filter, because during the use of the iPhone, without this filter will not have any impact on the iPhone. We can directly solder the jumper wire and ignore this filter.

After soldering the jumper wire, apply some green UV oil to fix it, and then install the iPhone. Test the iPhone, now the iPhone WIFI function is back to normal.
