4. Setup Guide

Follow these steps to set up your DBIT AC1200 WiFi Router:

Unpack the Router: Carefully remove the router and all accessories from the packaging.
Connect the Hardware:
- Connect your modem's Ethernet cable to the WAN port (labeled "WAN") on the router.
- Connect the power adapter to the router's DC-IN port and plug it into a power outlet.
- (Optional) For wired devices, connect an Ethernet cable from a LAN port (labeled "LAN1", "LAN2", "LAN3") on the router to your computer or other network device.
Power On: Wait for the router's indicator lights to stabilize. This usually takes a few minutes. Refer to the router's LED indicators for status.
Connect to the Network:
- Wireless Connection: On your computer or mobile device, search for available Wi-Fi networks. Select the network name (SSID) printed on the label at the bottom of your router. Enter the Wi-Fi password (also on the label) to connect.
- Wired Connection: If you connected your computer via an Ethernet cable, it should automatically connect to the router's network.
Access the Web Interface:
- Open a web browser (e.g., Chrome, Firefox, Edge).
- In the address bar, type the default IP address for the router (usually 192.168.10.1 or similar, check the router's label or user guide for the exact address) and press Enter.
- Enter the default username and password (typically "admin" for both, or as specified on the router's label).
Initial Configuration: Follow the on-screen setup wizard to configure your internet connection settings, Wi-Fi network name (SSID), and password. It is highly recommended to change the default Wi-Fi name and password for security.

5. Operating Instructions

Once set up, you can manage your router's functions through its web interface:

Network Settings: Configure WAN settings (DHCP, Static IP, PPPoE), LAN settings, and DNS servers.
Wireless Settings: Change Wi-Fi network names (SSIDs) for 2.4GHz and 5GHz bands, update passwords, adjust channel settings, and enable/disable guest networks.
Parental Controls: Set up time restrictions and content filtering for specific devices or users.
QoS (Quality of Service): Prioritize network traffic for certain applications or devices to ensure smooth performance for critical tasks like gaming or video streaming.
Security: Manage firewall settings, port forwarding, and VPN pass-through options.
System Tools: Access features like firmware upgrade, system logs, backup/restore configuration, and reboot options.

6. Maintenance

To ensure optimal performance and longevity of your router, consider the following maintenance tips:

Placement: Place the router in a central location, away from obstructions, large metal objects, and other electronic devices that may cause interference.
Ventilation: Ensure the router has adequate ventilation to prevent overheating. Do not cover its vents.
Firmware Updates: Regularly check for and install firmware updates from the DBIT official website or through the router's web interface. Firmware updates often include performance improvements, security patches, and new features.
Reboot Periodically: Rebooting the router every few weeks can help clear its memory and resolve minor performance issues.
Cleanliness: Keep the router clean and free of dust. Use a soft, dry cloth to wipe the exterior.

7. Troubleshooting

If you encounter issues with your DBIT AC1200 WiFi Router, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
No Internet Access	Incorrect WAN settings, modem issue, cable disconnected.	Check all cable connections (WAN port to modem, power). Reboot both the modem and the router. Verify WAN settings in the router's web interface match your ISP's requirements. Ensure your modem is working correctly.
Cannot Change Wi-Fi Name (SSID) or Password	Firmware bug, outdated software.	IMPORTANT: Upgrade the router's firmware via the admin page. This issue has been reported and can often be resolved with a firmware update. If the problem persists after firmware upgrade, contact DBIT customer support for assistance.
Slow Wi-Fi Speed or Frequent Disconnections	Interference, poor signal strength, too many connected devices, outdated firmware.	Relocate the router to a central, open area. Adjust antenna positions. Try changing the Wi-Fi channel in the router settings to avoid interference. Limit the number of active devices or consider using wired connections for high-bandwidth activities. Ensure firmware is up to date.
Cannot Access Router Web Interface	Incorrect IP address, network configuration issue, router not powered on.	Ensure your device is connected to the router's network (wired or wireless). Verify you are using the correct IP address (e.g., 192.168.10.1). Try clearing your browser's cache or using a different browser. Reboot the router. If all else fails, perform a factory reset (see manual for reset button location and procedure), but note this will erase all custom settings.
