This method allows for more detailed configuration.

192.168.1.1or192.168.0.1) or the default domain name (e.g.,repeater.net) found in the quick start guide. - Follow the on-screen instructions to select your main Wi-Fi network and enter its password.

4. Operating Modes
The WONLINK 3503-4 supports multiple operating modes to suit various network requirements:
- Repeater Mode: Extends the coverage of an existing Wi-Fi network. This is the most common mode for eliminating Wi-Fi dead zones.
- Access Point (AP) Mode: Converts a wired network connection into a wireless one. Ideal for areas with only wired internet access, creating a new Wi-Fi hotspot.
- Router Mode: Functions as a primary router, creating a new private network from a modem connection.
You can switch between these modes via the web interface settings.
