The name of the network is that? If so, how is that a CoxWifi hotspot? The name should be "CoxWifi". Also, I searched that area and the closest AP is at Frausto’s Street Tacos across the street at 1910 N La Cañada Dr # 4, Green Valley, AZ 85614.
COULD Be, but the address provided is an apartment complex, so either they ARE trying to find a Cox Hotspot, or they are connecting to their pano modem, (BTW, the wpa/preshare key is posted on the bottom on the sticker if it IS your modem), and if it's someone else's wifi, then accessing it without their permission is a federal offense.
