- Press the Power button to turn on the router. The Power LED should illuminate.
- (Optional) Connect a computer or other network device to one of the RJ45 LAN ports using an Ethernet cable.
- (Optional) Connect an analog or DECT phone to the RJ11 port for voice call functionality.
4.3 Initial Configuration (APN Settings)
After powering on, the router will attempt to connect to the mobile network. If it doesn't connect automatically, you may need to configure the Access Point Name (APN) settings manually.
- Connect your computer or smartphone to the router's Wi-Fi network (SSID and password are usually found on a sticker on the router).
- Open a web browser and navigate to the router's management interface, typically http://192.168.1.1.
- Log in using the default username and password (refer to the sticker or quick start guide).
- If the interface is in a language other than English (e.g., Finnish), look for a language selection option (often labeled "KIELI") and change it to English.
- Navigate to the network settings or APN settings section.
- Enter the APN for your mobile operator. Examples:
- SFR: websfr
- Orange: orange (username: orange, password: orange)
- Free Mobile: free
- Bouygues Telecom: Often auto-detects APN.
- Save the settings. The router should now connect to the internet.
- Note on IPv6: If you experience connectivity issues, especially with certain operators, ensure your connected devices are IPv6 compatible or configure the APN for IPv4 only if necessary.
