replace the 5GHz Wi-Fi antenna
Did you buy the housing with flexes already installed? In the early days with another supplier I found the housings always had poor quality or faulty parts installed. I had this issue on a 5C housing I replaced once, and it was the lightning port flex on the new housing. So I simply transferred the original one over to the new housing. The cellular antenna is on the back of the speaker, but connects to the motherboard via the lightning port flex and cable. Wifi antenna is at the top of the phone, and nothing to do with cell reception.
