USB-powered WiFi adapter, TV dongle, and repeater — one compact device that adds wireless connectivity with no extra power supply or driver discs required. Key benefits Add WiFi to a desktop or laptop: connect the device to your PC using an RJ45 Ethernet cable; the USB head supplies power and the device receives WiFi from your router. No CD driver required. Use with a smart TV: set the adapter on a computer to connect to your WiFi router, then attach the network via Ethernet to any smart TV that needs a wired input. Extend wireless coverage: set the device to repeater mode to boost your existing WiFi signal. The USB head provides power, so no AC adapter is necessary. Functions and compatibility Functions: WiFi adapter for computers, WiFi TV adapter/dongle, and WiFi repeater. Connectivity: RJ45 Ethernet cable to the computer or TV; receives wireless signal from a WiFi router. Power: USB head used to power the device; no external AC adapter required.
