4.2 Initial Configuration (Pre-configured Kit)
The KuWFi N650 kit is pre-configured for ease of use. In most point-to-point scenarios, the units will automatically pair upon power-up. One unit acts as the 'Master' and the other as the 'Slave'.
If manual configuration or advanced settings are required, follow these steps:
- Connect to the WiFi Bridge: Connect your computer to one of the N650 units via Wi-Fi or Ethernet. The default Wi-Fi password is 12345678.
- Adreça IP fixa: Temporarily set your computer's IP address to a static IP within the same subnet as the bridge (e.g., 192.168.1.10, Subnet Mask 255.255.255.0).
- Accés Web Interfície: Obre a web browser and navigate to the bridge's default IP address, typically 192.168.1.20. Enter the default username (admin) i contrasenya (admin) per iniciar sessió.
- Configure Master Unit: En el web interface, navigate to Wireless Settings > Basic Settings. Set the 'Mode' to AP. This unit will function as the Master Bridge.
- Configure Slave Unit: Inicieu sessió a web interface of the second N650 unit. Set its 'Mode' to Estació. This unit will function as the Slave Bridge and connect to the Master.
- Restore IP Address: After completing all configurations, revert your computer's IP address settings back to 'Obtain an IP address automatically' to allow normal network access.

5. Modes de funcionament i aplicacions
5.1 Point-to-Point Topology
In a point-to-point setup, two N650 units establish a direct wireless link to connect two separate networks or extend a single network to a remote location. This is the simplest configuration and is commonly used for connecting a main building to an outbuilding like a garage or workshop.

- Ensure both units have a clear, unobstructed line of sight.
- Verify that both units are powered on and their indicator lights are functioning correctly.
- Check all Ethernet cable connections for proper seating and integrity.
- Confirm that the Master and Slave units are correctly configured (AP mode for Master, Station mode for Slave).
- Adjust the alignment of the units to optimize signal strength.
- No es pot accedir Web Interfície:
- Ensure your computer's IP address is temporarily set to a static IP within the bridge's subnet (e.g., 192.168.1.10 for a bridge at 192.168.1.20).
- Verify you are using the correct default IP address (192.168.1.20) and login credentials (admin/admin).
- Prova una altra web navegador o esborra la memòria cau del navegador.
