Thank you for viewing! 【2-in-1 & Both Parent and Child Devices】 This wireless LAN adapter can be used as both a parent and child device. In station mode (child device), it allows old computers that require a wired cable to receive Wi-Fi. In AP mode (parent device, Windows 10 and later systems), it can provide Wi-Fi to smartphones, tablets, laptops, etc. However, when used as a parent device, the wireless LAN needs to be registered on the network access equipment. 【USB 3.0 Port & High-Speed Communication】 USB 3.0 is 10 times faster than USB 2.0, providing the best throughput performance and a more stable internet connection for Wi-Fi adapters. This wireless LAN adapter supports ultra-high-speed connections of up to 5GHz band (867Mbps) + 2.4 GHz band (300Mbps), with a maximum communication speed of 1200Mbps. It enables the transfer of large amounts of data in a short time without frustration. 【11ac Technology & Dual Band】 High-speed communication with dual-band; communication speed decreases as the number of connected devices increases. If the Wi-Fi USB is close to the router, or if you are watching videos or playing online games, the 5G band is recommended. If the wireless LAN adapter is far from the router, or if you want to surf websites, the 2.4G band is recommended. Note: You need to install the driver before connecting to the internet. 【5dBi Antenna & Wide Range】 The 360-degree omnidirectional 5dBi high-gain antenna ensures high RF power. It strengthens the radio waves compared to conventional 2dBi/3dBi antenna type Wi-Fi adapters, and can extend the radio waves over obstacles such as walls to a wider range. The 5dBi antenna helps to connect even when the signal is weak. It can be easily installed where you need to pick up the optimal signal.
