Enjoy the freedom of Wi-Fi connectivity for any of your Ethernet enabled devices at home or in the office with IOGEAR's Ethernet-2-WiFi Universal Wireless Adapter.

Turn Legacy Gadgets, Printers, VOIP into High Speed Wi-Fi Enabled Devices

Older laptops, A/V receivers, network printers and other Ethernet only devices leave you at the mercy of a hardwired data connection. With IOGEAR's Ethernet-2-WiFi Universal Wireless Adapter, you can breathe new life into your legacy electronics by giving them Wi-Fi capability.

Maximize Transfer Speeds

Using dual antennas (2T2R), the adapter delivers data rates up to 300Mbps and boasts speeds twice that of IOGEAR's Universal Wireless-N Adapter (GWU627). The increased speed supplies sufficient bandwidth for faster file transfers, music downloads, video streaming, online gaming, and HD multimedia applications.

Compact Design - Maximum Versatility

Designed to be thinner and lighter to make applications clean and clutter free, the Ethernet-2-WiFi Adapter is 40% smaller than its predecessor, without having to sacrifice performance. The compact design gives you the freedom to place your home entertainment center practically anywhere and stay connected to your wireless network.

Powered by USB

No need for power from an outlet, this device is powered by a USB port giving you more freedom to place it anywhere. For instance, the prevalence of USB ports on TV sets allow for simple and fast connection of the Ethernet-2-WiFi Adapter to any USB enabled television using the included USB power cable.

Wi-Fi Protected Setup™ (WPS) Support

Instantly connect to your network with the push of a button. IOGEAR's Ethernet-2-WiFi Adapter supports Wi-Fi Protected Setup (WPS), giving you the capability of connecting to your Wi-Fi network with all your personal security presets without any extra configuration for the Wi-Fi connection.

Secured Wi-Fi Network

IOGEAR's Ethernet-2-WiFi Universal Wireless Adapter maintains the highest level of security across your network. This device supports WEP, WPA, WPA2, TKIP and AES encryption standards to keep your wireless connection safe from intruders.
