iPhone 6 - Wifi 2.4Ghz Very Weak, 5Ghz Works Good BT too
# 5 Ghz works perfect # Bluetooth works perfect # GPS works perfect # '' 'WiFi signal 2.4 Ghz is very weak' '' I read quite all questions posted here, the more I could not solve my problem. I'm sure it is a hardware failure that has already performed all software testing I tried a few things I've seen posted here ... Images are illustrative and not real ... I tried to clear the Wi-Fi contacts that are located in the upper left corner of the board logic. Unsuccessfully. [image|875249] I removed all the logic board and tried to clean the contacts again, this time cleared the front and back ... also without success. Multiple users suggest scratch the Wi-Fi contacts for better conduct of the board, also performed unsuccessfully. And finally I checked if the plugs from the back of the logic board are four slots if they were correct, without success .... [image|875250] Already exhausted attempts, does anyone have any idea? Sorry my bad English ...
