Hi @elikagurning
Check that both co-ax antenna cables are securely connected at the main board end and the charge port board.
Here's the ifixit [guide|133543] guide that will help. See the images in Step.11 (blue and white cables mainboard) and Step.15 (blue and white cables charge port board).

Hai @elikagurning
Periksa apakah kedua kabel antena co-ax tersambung dengan aman di ujung papan utama dan papan port pengisi daya.
Berikut panduan ifixit [guide|133543] yang akan membantu. Lihat gambar di Langkah.11 (mainboard kabel biru dan putih) dan Langkah.15 (papan port pengisi daya kabel biru dan putih).
