The IOGEAR GWU637 Universal Ethernet to Wi-Fi N Adapter is a versatile solution for converting Ethernet-only devices into Wi-Fi-enabled ones. With speeds of up to 300Mbps on the 2.4GHz band, it supports WEP, WPA, WPA2, TKIP, and AES encryption for secure connections.

Users have praised its ease of setup, especially with the push-button Wi-Fi Protected Setup (WPS). However, some noted that setup can be tricky with certain browsers like Chrome and Firefox, recommending Internet Explorer or Safari instead.

The adapter's compact design and USB power option make it highly portable and easy to place anywhere. It’s particularly useful for older devices like network printers, A/V receivers, and legacy gadgets that lack built-in Wi-Fi.

While the device performs well within its range (about 50 feet), some users reported it gets extremely hot during operation. Additionally, it only supports 2.4GHz wireless bands, which may limit speed compared to 5GHz options.

Overall, the IOGEAR GWU637 is a reliable bridge for Ethernet devices needing wireless connectivity, though non-technical users might find the setup process challenging.
