Universal Ethernet-to-Wi-Fi bridge

The IOGEAR GWU637 adds 2.4 GHz wireless networking to any device that only has an RJ-45 port. It supports IEEE 802.11b/g/n at up to 300 Mbps and handles 64-bit or 128-bit WEP, TKIP, AES, WPA and WPA2 security. The adapter suits HDTVs, game consoles, Blu-ray players and other legacy electronics that lack built-in Wi-Fi.

Bundled power and cabling

A USB power cable, USB power adapter and a three-foot Ethernet cable ship in the box so the unit can run without a spare USB port on the target device. The quick-start guide walks through WPS and manual setup, while the warranty card covers the hardware. No software disc or driver download is required because the bridge operates transparently at the network layer.

Plug-in installation

Connect the Ethernet cable from the device to the adapter, supply power via the USB adapter, then join the wireless network using WPS or the web interface. The only common hurdle is entering the correct Wi-Fi password when WPS is unavailable. The adapter runs from 0 to 50 °C and stores from -10 to 70 °C at 5 to 95 % non-condensing humidity.

Questions about this item

Does the GWU637 require any periodic maintenance or component replacement during its service life?

The adapter has no moving parts or user-serviceable components, so no scheduled maintenance or part replacement is needed.

What is the first performance limit reached when the GWU637 runs at full 300 Mbps throughput for extended periods?

Sustained maximum throughput will hit the 300 Mbps ceiling of the 802.11n radio before any other bottleneck appears.

How much heat does the GWU637 generate and what is its operating temperature range when powered continuously?

The unit operates from 0 to 50 °C with no fan; its low transmit power (under 17 dBm) keeps heat output minimal during all-day use.
