The smallest Wi-Fi router, with dimensions smaller than half the size of a credit card, ideal for business travel and home use. Low power consumption, total power supply under 4W. Includes a dedicated dual-function cable combining power supply and Ethernet connectivity, reducing cable clutter and improving convenience. Supports intelligent Wi-Fi bridge mode with three operational modes: a) Wi-Fi AP Client mode (enables wireless-to-wired Ethernet connection); b) Wi-Fi Hotspot mode (suitable for hotel room use); c) Wi-Fi Repeater mode (extends Wi-Fi signal coverage). In intelligent bridge mode, supports automatic Wi-Fi hotspot scanning and hotspot memory function. Complies with IEEE 802.11b/g/n standards, delivering up to 300Mbps data transfer rate. Broad compatibility with smartphones, tablets, laptops, and other Wi-Fi-enabled devices. Functions as a Wi-Fi router, Wi-Fi bridge, and Wi-Fi repeater in one device. Features one WAN port and one LAN port—both ports are interchangeable. Compact design with dual Ethernet ports is uncommon for this size. Uses proprietary VDNS virtual domain configuration technology for simplified setup. Incorporates proprietary D/A temperature-compensated automatic frequency control (TAFC) technology for stable, uninterrupted Wi-Fi performance. Powered via USB (DC 5V). Interfaces: - One 10/100M adaptive Ethernet female port; - Dedicated dual-function cable (power + 10/100M adaptive Ethernet); - Ethernet port supports interchangeable WAN/LAN functionality.
