2560 Mega Wifi cannot initialize ESP module

I finally got it working again.   It seems like it wants 115200 to work.   The SSID information is in Arduino_WIFI.h.  With 1-4 ON and 5-8 Off, you need to change the switch to TXD3/RXD3 and change four lines from Serial1 to Serial3.

@scsiraidguru Yes, you have to match the serial monitor to the sketch for baud rate.

The notes on most sites had them 115200 and 9600.   I just glad to get it working again.  

@scsiraidguru As long as they match, I used to do 9600 out of habit, but for the last year or so I choose 115200.
