there might be a problem with your logic boardl, it seems to me that your motherboard hould be repaired or replaced. i've seen that you can reflow (resolder) the wifi chip which sometimes gets knocked loose. you can venture out and do it yourself.
if you look for repair guides online for a motherboard replacement you will find something. I work for company that does iPHone repair in NYC and we do this repair frequently.
