4。 動作モード
The SecuFirst REP240 supports three distinct operating modes to cater to various network needs:
Figure 4.1: Visual representation of the three operating modes: Wireless Repeater mode, Wireless AP mode, and Client mode.
4.1. リピーターモード（デフォルト）
In Repeater Mode, the REP240 extends the coverage of your existing Wi-Fi network. It receives the wireless signal from your main router and re-broadcasts it, effectively eliminating dead zones and improving signal strength in areas with poor reception. This mode is ideal for expanding your Wi-Fi coverage without running new cables.
4.2. アクセスポイント（AP）モード
In AP Mode, the REP240 transforms a wired internet connection into a wireless hotspot. You connect the REP240 to your router or modem via an Ethernet cable, and it then creates a new Wi-Fi network. This mode is useful in situations where you have an Ethernet port available but need to provide wireless access, such as in a hotel room or a part of your home with a wired connection but no Wi-Fi.
4.3. クライアントモード
Client Mode allows you to connect a wired-only device (e.g., a desktop computer, smart TV, or gaming console) to your wireless network. In this mode, the REP240 connects wirelessly to your main Wi-Fi network and provides an Ethernet port for your wired device. This is beneficial for devices that lack Wi-Fi capabilities but need internet access.
