3. Setup Guide
3.1 Initial Hardware Connection
- Connect the broadband cable from your modem to the WAN port (blue port) of the router.
- Connect the provided power adapter to the router's Power Connector and plug it into a power outlet.
- Wait for the router to power on and boot up. Observe the indicator lights: they will initially be constantly red, then flash green, blue, and red alternately. Once successfully booted and connected to the internet, the indicator light will turn green and remain constant (blinking during data transmission).
3.2 Connecting to the Default Wi-Fi Network
- On your mobile phone or computer, search for available Wi-Fi networks.
- Connect to the default Wi-Fi network named "WR1200S-XXXX" (where XXXX represents the last four digits of the router's MAC address).

3.3 Router Configuration via Web Interface
- Open a web browser (e.g., Chrome, Firefox, Safari) on your connected device.
- In the address bar, type "192.168.100.1" and press Enter.
- You will be prompted for a username and password. Enter "admin" for both the username and password.
- Click the "Login" button to access the device setup wizard.
Note: If your phone prompts "WR1200S-XXXX cannot access the Internet. Allow WLAN Assistant to switch to a better network?", click 'Disallow' or 'No' to continue with the router setup process. Otherwise, the setup may not complete.
- Follow the on-screen instructions in the "Setup Wizard – WiFi" page. You can modify the Wi-Fi name (SSID) and password for both 2.4GHz and 5GHz bands.
- Click 'Next' to proceed to the "Setup Wizard – Network" page. Choose the correct internet connection type (e.g., Dynamic IP, PPPoE) and configure parameters based on information from your internet service provider.
- Click 'Next' to view the "Setup Wizard - Summary" page, which displays your configured Wi-Fi and network settings.
- Verify the information is correct, then click the 'Apply' button to save the configuration. A dialog box "Setup Wizard Saved Successfully" will confirm the settings.

4. Operating Modes and Features
4.1 Multiple Operating Modes
The FENVI AC1200 router supports various operating modes to suit your network needs:

- Router/AP Mode: Transforms your wired network into a wireless network, acting as the primary access point.
- Repeater Mode: Extends the coverage of an existing Wi-Fi signal from your main router, ideal for bridging signals to dead zones.
4.2 Dual-Band Integration (Smart Connect)
The router supports dual-band integration, allowing the 2.4GHz and 5GHz Wi-Fi networks to share the same name (SSID). This feature is disabled by default. When enabled, your devices will automatically connect to the faster Wi-Fi signal available.
To enable Dual-Band Integration:
- Connect your device to the router's Wi-Fi.
- Open a web browser and enter "192.168.100.1" to access the router's management page.
- Navigate to the [Wireless] -> [WiFi] management page.
- Enable the "Dual-band Integration" feature.
- Click the [Apply] button to save the settings.
- You can change the name and password for the integrated dual-band network. After saving, your devices will automatically connect to the new Wi-Fi network with the updated password.
If you wish to connect specifically to the 5GHz Wi-Fi, you can disable the dual-band integration feature and set different names for the 2.4GHz and 5GHz networks. Your device can then manually select the 5GHz network.
4.3 WPS (Wi-Fi Protected Setup) Connection
WPS allows for easy and secure connection of compatible devices to your Wi-Fi network without manually entering the password.
- For first-time usage, log in to the router's management interface (192.168.100.1) and go to the [Wireless] -> [WPS] page to enable WPS.
- Lightly press the WPS button on the router.
- Within two minutes, enable the WPS connection feature on your mobile device or other Wi-Fi device. This will initiate the standard WPS negotiation and connect your device to the router's Wi-Fi network.
Note: Some mobile devices support this feature. Search for "WPS" in your device's settings.
5. Maintenance
5.1 Optimal Placement
- Place the router in a central location within your home to ensure the widest possible signal coverage.
- Avoid placing the router near large metal objects, thick walls, or other electrical equipment (like microwaves, cordless phones) as these can cause signal interference and reduce Wi-Fi performance.
- Ensure adequate ventilation around the router to prevent overheating, which can affect performance and longevity.
5.2 Factory Reset
A factory reset can resolve various issues by reverting the router to its original settings. All custom configurations will be lost.
- Ensure the router is powered on and has fully booted up.
- Using a pointed object (e.g., a paperclip), press and hold the RESET button on the router for more than 5 seconds.
- Release the button when the indicator light goes off.
- The router will restart. Once it has rebooted and established a connection, the factory reset is complete.
Note: After a factory reset, you will need to reconfigure the router using the setup guide (Section 3).
