No Wifi/BT, try everything without success but put in a freezer returns WiFi



Hi all, two weeks ago bought a Nexus 5. Came with Android 5.0.1. Well out of the box I have no WiFi access. I saw no WiFi, while my laptop saw it. I was on a business trip in a hotel in Miami. Suddenly walking through the corridors of the hotel, detect a few WiFi AP but I could not connect. Back home, I put 3G data and immediately I get the OTA to Android 5.1.0. From there, the WiFi worked and I could connect to my account and download applications. Moments later, came a new OTA to Android 5.1.1 moment in which everything stopped working.

Using Nexus Root Toolkit I have tried all official image, place the router on 2.4, low channels, clean cache and what all Forum recommends. Finally try to put the phone in the freezer. Leave it for ten minutes. When I power on, I went back to see all networks and connect to my WiFi for 15 minutes approximately. Once the phone returned to temperature environment, the WiFi disappeared and I went back to the same situation. If I put it in the frezer it works, until it takes ambient temperature.

I can turn on or off the WiFi, but I do not see anything, I can see the MAC Address, when turn on the wifi the button turns blue, everything its works fine but without any success. Currently the phone has Android 5.1 image LMY47I and the M8974A-2.0.50.1.16 RADIO (did a downgrade thinking that could improve something). Currently I have OTA to migrate to 5.1.1. I dont know if I will give a try to this upgrade.

I would like to know if there is any way that the phone does not validate the temperature or something similar because when he leaves the refrigerator "cold", everything works for a few minutes until it returns to a temperature environment.

Any thoughts?
