Key Features

The IOGEAR GWU637 enables compatible Ethernet devices to connect to Wi-Fi, providing wireless access to any Ethernet-enabled device at home or in the office. Once configured simply connect an Ethernet cable from the GWU637 to your device.
Not Compatible with Enterprise Authentication or Mesh Networks — Designed to connect directly to a wireless router. Hotspots, repeaters, and access points are not guaranteed to function properly. This will not create a hotspot or a secondary network. Not compatible with open or hotel networks.
Maximize Transfer Bandwidth — Using dual antennas (2T2R), the adapter delivers data rates up to 300Mbps with sufficient bandwidth for faster file transfers, music downloads, video streaming, online gaming, and HD multimedia applications. The true bandwidth capability is limited by your internet bandwidth of 2.4 Ghz. This will not work with 5 Ghz networks.
Turn Legacy Gadgets, Printers (LAN), 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 or wireless bridge capability.
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. Due to the compact design it is normal for the adapter to reach temperatures of approximately 122 degrees.
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.
