I have the I Pad air and the Square stand to take crdit cards. How do I sync the ATT connection on my I Pad to provide the WIFI connection I need to make sales in another location?
Let me see if I understand what you are asking. You are usig AT&T for you internet provider and want to be able to connect another iPad. Is you iPad in the square stand a cellular iPad with AT&T service? If so you just need to turn on the personal hot spot on that iPad and then connect the other iPad to it. You would do this like you connect to any WiFi just look for the name of your main iPad.
Let me know if this is not what you are asking.
