Chosen Solution
The antenna interconnect cable that plugs into the socket on the logic board has come apart. The socket pulled loose from the logic board. I lost the socket. How do I fix it ? Can I purchase this socket ? If so What is the name and part number to this socket ?
Those antenna connectors are not easy to source. It seems like there are quite a few different sizes being used. Your best bet is to get one from a donor board. If you don’t have an Air donor, look at other iDevices to see if you can find one that matches.
