Found out the wifi being shut off then coming back on when the screen is active is not the problem.
The problem with the wifi appears after having the phone plugged into the usb port on the computer. After I am through charging it, moving files or whatever then the wifi acts retarded.
I have been charging it with the wall charger and car charger and the problem hasn't came back.
The GPS was still stuck last Monday when I tried to use it. It was still saying I was in the ocean
I waited patiently and a few minutes later it corrected itself and showed my actual location.
