In General, in Jiayu G2 it's the antenna — suddenly disappeared communication, there is only 1-2 meters from the router. Software and connecting the dances with a tambourine do not give, so the conclusion is — it is in the gland. I want to try to replace it, pull, etc., but do not want random to unstick everything.
Plz help to find it? I enclose a few pictures of its innards from the Internet, for the first tsiferki marked in the existing aerial.
