5.2 Managing Connections (Primary and Guest)
The H100 supports both a primary and a guest Wi-Fi network. This allows you to provide internet access to guests without sharing your main network password or access to your primary connected devices.
- Primary Network: Your main Wi-Fi network, typically with full access and higher priority.
- Guest Network: A separate Wi-Fi network with its own password, often with limited access or bandwidth, ideal for temporary users.
Navigate the H100's on-screen menu using the navigation button (often the power button or a dedicated navigation button) to view and manage settings for both networks.
5.3 Using the Display
The color display provides crucial information at a glance. Use the navigation button to cycle through different screens, which may include:
- Network status (4G LTE, signal strength)
- Battery level
- Connected devices (Primary and Guest)
- Wi-Fi SSID and password
- Data usage
5.4 Network Settings
Advanced network settings can typically be accessed via a web interface. Connect a device to the H100's Wi-Fi, then open a web browser and enter the IP address displayed on the H100's screen (e.g., 192.168.1.1). Log in using the default credentials (usually found in the Quick Start Guide or on a sticker inside the device) to configure settings such as:
- Changing Wi-Fi SSID and password
- Setting up security protocols
- Managing connected devices
- Firmware updates
