6. Troubleshooting

6.1 No Internet Connection

• Check Cables: Ensure all cables (power, DSL/WAN, Ethernet) are securely connected.
• LED Status: Verify the Power, DSL/WAN, and Internet LEDs are solid green. If the DSL/WAN LED is flashing, there might be an issue with your internet line or connection type. If the Internet LED is off, check your ISP settings in the router's web interface.
• ISP Credentials: Confirm that your internet service provider (ISP) username and password are correctly entered in the modem router's configuration.
• Restart Devices: Power cycle the modem router and any connected devices (computer, NBN/UFB NTD) by unplugging them for 30 seconds and then plugging them back in.

6.2 Wi-Fi Connection Issues

• WLAN LED: Ensure the WLAN LED on the front panel is solid green. If it's off, Wi-Fi might be disabled. Check settings in the web interface.
• Correct Password: Verify you are entering the correct Wi-Fi password (network key).
• Signal Strength: Move closer to the modem router to check if signal strength is an issue. Obstacles like walls and large appliances can interfere with Wi-Fi signals.
• Channel Interference: In congested areas, changing the Wi-Fi channel in the router's settings may improve performance.

6.3 Slow Internet Speed

• Number of Devices: Too many devices actively using the network can reduce speeds.
• Interference: Other wireless devices (cordless phones, microwaves) can cause interference.
• Firmware: Ensure your modem router has the latest firmware installed.
• ISP Issue: Contact your internet service provider to check for any network issues in your area or with your service plan.
