Instruccions de configuració
The IOGEAR GWU637 adapter can be configured using two primary methods: Wi-Fi Protected Setup (WPS) for quick connection, or a manual setup process via a web navegador.
WPS Setup (Recommended for compatible routers)
- Ensure your wireless router supports WPS and that the WPS function is enabled.
- Connect the IOGEAR GWU637 adapter to a power source using the provided USB cable and power adapter.
- Press and hold the WPS button on your wireless router to initiate the WPS pairing process.
- Within two minutes, press and hold the WPS button on the IOGEAR GWU637 adapter until the WLAN LED begins to flash. This indicates the adapter is attempting to connect to your router.
- Once the WLAN LED on the adapter becomes solid, the connection is established.
Nota: Pressing the WPS button on the adapter will erase and replace any previously saved configurations.

Manual Setup (For routers without WPS or specific configurations)
- Connect the IOGEAR GWU637 adapter to a power source using the provided USB cable and power adapter.
- Connect the adapter to a computer (PC or Mac) using the provided Ethernet cable. Ensure the computer's Wi-Fi is temporarily disabled to prevent conflicts during setup.
- Obre a web browser (Firefox, Internet Explorer on Windows, or Safari on macOS) and navigate to the adapter's default IP address (refer to the Quick Start Guide for the specific IP address, typically 192.168.1.252).
- Seguiu les instruccions que apareixen a la pantalla web interface to scan for available Wi-Fi networks, select your desired network, and enter the Wi-Fi password (security key).
- Save the settings and disconnect the adapter from the computer. The adapter is now configured for your Wi-Fi network.
Nota: Pressing the WPS button on the adapter will erase and replace any previously saved configurations, including those from manual setup.

Instruccions de funcionament
Once the IOGEAR GWU637 adapter is successfully configured to your Wi-Fi network, it functions as a bridge, allowing any Ethernet-enabled device to connect wirelessly.
- Ensure the adapter is powered on via its USB connection. It can be powered by a USB port on your device (e.g., TV, gaming console) or the included USB power adapter.
- Connect one end of the Ethernet cable (provided) to the Ethernet port on the IOGEAR GWU637 adapter.
- Connect the other end of the Ethernet cable to the Ethernet (LAN) port of the device you wish to connect to Wi-Fi (e.g., smart TV, Blu-ray player, network printer, desktop PC).
- The device should now have network access via the Wi-Fi connection established by the IOGEAR GWU637 adapter. No additional drivers or software are required on the connected device.

- Velocitat de connexió lenta:
- Ensure the adapter is within optimal range of your wireless router. Obstacles like walls can degrade signal strength.
- Minimize interference from other 2.4GHz devices (e.g., cordless phones, microwaves).
- Verify your internet service provider's speed and your router's capabilities. The adapter's maximum speed is 300Mbps, but actual speeds depend on your network environment.
- La configuració de WPS ha fallat:
- Ensure your router's WPS function is active and you are pressing the correct WPS button on both the router and the adapter within the allowed timeframe.
- If WPS continues to fail, use the manual setup method via a web navegador.
- L'adaptador s'escalfa:
- It is normal for the adapter to become warm during operation, reaching temperatures up to approximately 122°F (50°C). This does not indicate a malfunction.
