Refer to the documentation for your device for generic configuration instructions:

• Connect to the router’s Wi-Fi network using your computer, tablet or smartphone. Note: The default Service Set IDentifier (SSID) and wireless network encryption key should be indicated on your hotspot. NOTE: iOS devices (iPhone, iPad or iPod Touch) have a feature called Auto-Login which is enabled by default, and can cause your iOS device to be disconnected from the hotspot’s Wi-Fi network. To turn Auto-Login off:
• On your iOS device, go to Settings / Wi-Fi.
• Find the hotspot’s Wi-Fi network name in the list of networks, and tap the (i) to the right of the name.
• Turn off the Auto-Login setting.
• Connect to the router's admin interface. For example, open http://192.168.1.1 in your web browser. The url for your device may be different.
• Click the “Log In” link: e.g. Username - admin, Password - admin. Username and password for your device may be different.
• Verify that the Profile (APN) setting is set to "gigsky" (without quotation marks). You will have to create a new profile if one doesn't already exist for GigSky:
• APN type = Static
• APN name = gigsky
• Leave the User name and Password fields blank.
• Verify the Network Settings:
• Auto select network
• Auto connect to network
