My LG G3 is disconnecting from wifi, I have already tried Safe Mode, rebooting our router and modem, I have took out the battery, and I have now done a factory reset and NOTHING has worked. I even have tried the Verizon Repair Assistant and it says the phone is fine. I had to get a new SIM card last week because the phone couldn't "find" my SIM card. Just today it has showed "no SIM card" twice. I have never had any problems with my phone until last week, and just happens to be when my last payment on the phone was made. Coincidence? Everything else in the house that is connected to WiFi is working fine, its just my phone.
Can anyone point me in the direction on how to have this fixed?
