5. Mod Operasi

The D-Link DIR-825M supports multiple operating modes to adapt to various networking needs.

• Mod Penghala (Lalai): In this mode, the device acts as a primary router, connecting to your modem to provide internet access to all connected wired and wireless devices on your local network. It performs Network Address Translation (NAT) and manages IP addresses.
• Mod Titik Akses (AP): This mode allows the DIR-825M to extend an existing wired network with wireless capabilities. It connects to an existing router via an Ethernet cable and broadcasts a Wi-Fi signal, essentially turning a wired network into a wireless one without performing routing functions.
• Mod Pengulang: Also known as Wi-Fi Extender mode, this allows the DIR-825M to wirelessly extend the coverage of an existing Wi-Fi network. It connects to an existing Wi-Fi signal and re-broadcasts it, helping to eliminate Wi-Fi dead zones.
• WISP Repeater Mode: Wireless Internet Service Provider (WISP) Repeater mode enables the router to connect wirelessly to a WISP access point and then share that internet connection with both wired and wireless clients on your local network. This is useful in areas where wired internet access is unavailable.
• Wi-Fi Client Mode: In this mode, the DIR-825M acts as a wireless adapter for a wired device. It connects wirelessly to an existing Wi-Fi network and provides an Ethernet connection for a single wired device that does not have its own Wi-Fi capability.

You can switch between these modes through the router's web-based management interface, typically found under the 'Operation Mode' or 'System Settings' section.
