The ciewia USB-A 2.0 Female to RJ45 Male Adapter (Pack of 2) allows you to use a standard USB cable as an Ethernet cable by connecting two adapters between devices. Designed for specific professional applications including ADSL modem-to-computer connections and surveillance camera setups. Lightweight and portable.

⚠️ Important: This adapter has ONLY 2 supported use cases (see below). It will NOT provide direct internet access from a router to your laptop or PC. It does NOT work with USB 1.1 (printer-style USB). A PoE data switch is required for network data transmission. Please read the full description before ordering.

• 【Only 2 Supported Use Cases】
  1. Connect a USB ADSL modem or USB-interface router to a device with an RJ45 port (requires PoE data switch).
  2. Connect a professional surveillance camera (RJ45/LAN) to a regular USB camera for simultaneous operation on the same network.
• 【Pack of 2 — Use as Ethernet Cable Replacement】 Use both adapters together with a USB cable (not included) to bridge two Ethernet ports: one adapter connects to your computer's RJ45 port, the other connects to your modem's RJ45 port. The USB cable acts as the Ethernet cable between them.
• 【USB-A 2.0 Female to RJ45 Male (8P8C)】 One end is a USB-A 2.0 female port; the other end is an RJ45 male plug (8P8C). Passive physical adapter — no drivers required for supported use cases.
• 【VoIP & Telephony Compatible】 Can also be used with VoIP and telephony applications to connect and transfer data between networks (requires PoE data switch).
• 【Lightweight & Portable】 Compact design, easy to carry. Suitable for field use, home networking, and professional AV/surveillance setups.

How to Connect (Pack of 2 Setup)

1. Insert the RJ45 male end of Adapter 1 into your computer's RJ45 network port.
2. Insert the RJ45 male end of Adapter 2 into your modem's RJ45 network port.
3. Connect both USB-A female ends together using a USB cable (not included). The USB cable now acts as the Ethernet cable.
