The IOGEAR GWU637 Universal Ethernet to Wi-Fi N Adapter is a game-changer for those looking to connect Ethernet-only devices to a wireless network. With speeds of up to 300Mbps on the 2.4GHz band, this adapter ensures that your legacy gadgets, printers, and even older laptops can enjoy seamless Wi-Fi connectivity.

One of the standout features is its ease of setup. The Push-button Wi-Fi Protected Setup (WPS) allows for a quick and secure connection. However, if WPS isn't available, users can set it up using Internet Explorer or Safari. Note that Chrome and Firefox may require a firmware update for proper functionality.

The adapter's dual antennas (2T2R) maximize transfer speeds, making it ideal for activities like video streaming, online gaming, and HD multimedia applications. Its compact design is 40% smaller than its predecessor, offering more placement flexibility without sacrificing performance.

Powered by USB, the GWU637 eliminates the need for an external power outlet, making it even more versatile. However, it's important to note that this device is not compatible with enterprise authentication or mesh networks and is designed to connect directly to a wireless router.

User reviews highlight both pros and cons. On the positive side, many users appreciate its solid connection and ease of use once configured. It's particularly praised for its ability to bridge devices onto the same subnet without creating isolated networks—a crucial feature for devices like Tivo tuners that require all connected devices to be on the same network.

On the downside, some users found the setup process challenging, especially when using browsers other than Internet Explorer or Safari. Additionally, the device tends to get quite hot during operation, which has raised concerns among some users.

Overall, the IOGEAR GWU637 is a reliable solution for those needing to connect Ethernet-only devices to a Wi-Fi network. While it may not be plug-and-play for everyone and lacks 5G support, its performance and versatility make it a worthwhile investment for bridging legacy devices into the wireless age.
