Chosen Solution
I recently replaced the loud speaker on a iphone 6s plus. Once I put it back together the wifi and bluetooth only worked intementantly and was weak. I took phone back apart and checked all connections and couldn’t see anything wrong. I started putting things back together and was able to get it working again. Now it’s been a few weeks and its back to dropping signal again. My thought is I may have damaged wifi/bluetooth cable, but I also notice several other “wifi” cables and I’m not sure where to begin. Nothing looked off so I’m struggling to figure it out. In the repair guides, I’m only seeing the one cable listed as both wifi and bluetooth so I’m thinking that’s it. Am I thinking correctly? Everything else including cellular is functioning properly.
Hi Jason My first guess would also be to check the wifi:bluetooth antenna is plugged in well. The coaxial connectors can be very tricky and might seem ‘clicked in’ while they are not. They are also very dust sensitive so best clean them with some rubbing alcohol. Look at step 47 of the repair guide. The connection is on the bottom of the motherboard so it’s easily overlooked that the antenna is dangling loose or not clicked in 100% iPhone 6s Plus Wi-Fi/Bluetooth Antenna Replacement
