The Totolink A2100UA is a 1267Mbps wireless dual-band USB adapter with a USB3.0 interface that allows you to easily connect to your router via USB. It supports sharing of the simultaneous 2.4GHz and 5GHz wireless signal with other wireless terminals from the Wi-Fi source, which makes it an ideal LAN card for your computer. Meanwhile, an external Omni-directional antenna greatly improves wireless reception sensitivity and Wi-Fi performance.

The Totolink A2100UA supports simultaneous 400Mbps on 2.4GHz and 867Mbps on 5GHz dual-band Wi-Fi, delivering wireless speed up to total 1267Mbps, which easily satisfies the demand for high-speed internet, such as online gaming, streaming videos online or streaming music.

The A2100UA has a built-in FEM module (Power amplifier + Low noise amplifier), which has a stronger Wi-Fi signal receiving ability. This creates a stronger signal and wider signal receiving range. Thanks to an external Omni-directional antenna, it greatly improves the wireless reception sensitivity and enables you to receive wireless signals from 360ø direction, which improves the wireless network coverage for the users.

The complied USB3.0 interface provides faster and more efficient data transfer rates while helping to transmit the wireless signal to your computer up to 2x faster than the traditional USB2.0 AC USB adapter. A secured wireless connection can be established with only one push on the WPS button, no need to input the tedious passwords anymore. Compatible with Windows 10/8.1/8/7/XP(32/64-bit) to meet the requirements of various desktop and laptop users for wireless internet connections.
