Ok so I was just starting to feel like it may somehow be a bad heater core and I plugged in a new rapido hotend just to at least rule it out. And it worked!!
No idea if it sent it to the moon on initial test and burned the heater core out or something but It appears to have just been the heater itself!
Sheesh!
@phaedrux your a wizard man. totally a wire in the drag chain... as soon as the hotend moves to the far side of the bed the wire for the fan is bent and when it straightens out in the chain it comes back on. Thanks!

Ok so for ATT users not familiar with networking settings.... in your IP gateway the option for advanced settings is a small blue link at the top of the home network/ wifi page. And thats where you can separate the 2.4 and 5 ghz bands with separate ssid names.
Worked finally! Separating the bands into two separate networks was the key.
