I am attempting to connect my laptop to the Epic Hotspot. My laptop is able to find SPH-D70002E (Epic) on my laptop's WiFi available net work list. When I click on that, I get a Window's error message: "Windows is unable to connect to the selected network. The network may no longer be in range. Please refres the list of available networks and try to connect again." The SPH-D70002E (Epic) is full bars strength. Any ideas?
