WIFI Reset?

I just received my board today

I plugged it in and the blue light blinked. I was able to see the ssid on my iphone but not on my computer.

I proceeded with the procedure on my iphone. Connected and went to IP address. Did the reboot and now I don't see the ssid. 

I have tried to reset the wifi. But when I hold down the reset button the blue light just blinks 3 times and turns off. 

I was planning on running through the procedure at one location and then taking to another location (different wifi) to install.

How do I reset back to blink in network discover mode?
