I’m so confused to what to replace in my iphone 6s plus. I recently changed housing. Did everything from the ifixit guide but in the end everything was working fine but WiFi was like awful. My WiFi is good only in 5~meters or lower in range of a router. I don’t know which flex i might have damaged. I tried to inspect my device but i came in no luck. It’s not the housing because i reverted back to OEM and i still have this issue. I have three options: 1: iPhone 6s Plus Top Left Wi-Fi Antenna 2: iPhone 6s Plus Wi-Fi/Bluetooth Antenna 3: iPhone 6s Plus Wi-Fi Diversity Antenna Which replacement part should i choose? I did some research on what might be, yet i didn’t find the satisfaction of my question. Is the diversity antenna a LONG RANGE WiFi and top left WiFi Antenna is SHORT RANGE? So in my case i have problem with Diversity Antenna? This is why im confused. Although i managed to some kind electrocute my board(forgot to disconnect battery) while i was trying to identify the issue. The electrocution part was on the right top where the lcd flex’s are set while trying to connect the(Not replacement) WiFi Diversity Antenna. It was a 1 second of orange light on the board where WiFi diversity connects. This is after the problem popped up not before, it wasnt booting for 5 minutes but after a short power cycle it’s back but still with the annoying WiFi issue!! Sorry for my bad English, trying my best.
Personally I see most wifi problems Solved by replacing the Top Left Wi-Fi Antenna and have done many of these successfully restoring full wifi function.
I am able to fix Low WI-FI signal problem.I changed both antenna flex but still same then finally got a solution that one filter is damaged.I am able to fix 3 more by this.This may help you to solved that problem.
