Chosen Solution
Hi! I am the only one in the house with this problem - When I go to my room, the wifi-signal on my iPhone disappears. I only have wifi-signal if I am in the room, where the router actually is. If I bring another iPhone or iPad to the room, they still have a good wifi-signal. And no, it has not always been like this. It started like 2 months ago. I have another problem - the bluetooth-signal is bad as well.. What to do?
You need to replace the logic board antenna.. Part: iPhone 6 Logic Board Antenna Flex Cable
Below are the three WiFi signal adapters. Usually bluetooth isnt effected by anything but the board connector, however, your wifi signal could be caused by multiple antennas. https://www.etradesupply.com/apple-iphon… https://www.etradesupply.com/apple-iphon… https://www.etradesupply.com/apple-iphon… If you replace these three antennas, and your issue is still not fixed, then you are looking at a Radio IC Failure. The IC used to process the WiFi, and the Blutooth both go through the same Chip on the board. in which case, you can replace the Logic Board, or take yours to someone with experience in SMT to fix the board you have.
