Setup

Step 1: Connect the Gateway

1. Connect one end of the provided DSL phone cable to the DSL port on the rear of the C3000A gateway.
2. Connect the other end of the DSL phone cable to your wall phone jack. If you have a phone connected to the same line, use a DSL filter (not included).
3. Connect the power adapter to the 12V==2A Power Input on the rear of the gateway and plug it into an electrical outlet.
4. Wait for the gateway to power on. The Power LED should turn solid green.

Step 2: Verify DSL and Internet Connection

1. Observe the DSL 1 and DSL 2 LEDs. They should turn solid green, indicating successful synchronization with the DSL line. If only one DSL line is active, only DSL 1 will be solid green.
2. Observe the Internet LED. It should turn solid green, indicating a successful connection to the internet. This may take a few minutes.

Step 3: Connect Your Devices

• Wired Connection: Connect an Ethernet cable from one of the Ethernet ports (1-4) on the gateway to the Ethernet port on your computer or other network device.
• Wireless Connection:
  1. Find the Wi-Fi network name (SSID) and password (WPA/WPA2 key) located on a sticker on the gateway.
  2. On your wireless device (laptop, smartphone, tablet), search for available Wi-Fi networks.
  3. Select your gateway's SSID (e.g., "CenturyLinkXXXX") and enter the password when prompted.
  4. Alternatively, press the WPS button on the front of the gateway and then activate WPS on your device within two minutes to establish a connection without entering the password.

Step 4: Access the Gateway Interface (Optional)

To configure advanced settings, open a web browser on a connected device and navigate to the gateway's default IP address (commonly http://192.168.0.1 or http://192.168.1.1). You will need to enter the administrator username and password, which are typically found on the gateway's sticker or in your ISP's documentation.

Operating Instructions

Connecting to Wi-Fi

The C3000A supports dual-band Wi-Fi, offering both 2.4 GHz and 5 GHz networks. The 2.4 GHz band provides wider coverage and better penetration through walls, while the 5 GHz band offers faster speeds over shorter distances and less interference. You can connect your devices to either network based on your needs.

• 2.4 GHz Network: Ideal for devices further away from the gateway or for general browsing.
• 5 GHz Network: Recommended for high-bandwidth activities like 4K streaming and online gaming, especially for devices closer to the gateway.

Using the USB Port

The USB 3.0 port on the rear of the gateway can be used to connect external storage devices (e.g., USB hard drives or flash drives) to create network-attached storage (NAS). This allows all devices on your network to access shared files. Refer to the gateway's web interface for configuration options.

Guest Wi-Fi Network (If Available)

Some configurations of the C3000A may allow you to set up a separate guest Wi-Fi network. This provides internet access to visitors without giving them access to your main network resources. Check the gateway's web interface for this feature.

Maintenance

Firmware Updates

The C3000A gateway's firmware is typically managed and updated remotely by CenturyLink to ensure optimal performance and security. You generally do not need to manually update the firmware. If you encounter issues, your ISP may push an update.

Resetting the Gateway

If you experience persistent network issues or forget your administrator password, you can perform a factory reset. Locate the recessed Reset button on the rear panel. With the gateway powered on, use a paperclip or similar pointed object to press and hold the button for approximately 10 seconds until the LEDs flash. The gateway will restart with factory default settings. Warning: A factory reset will erase all custom configurations, including Wi-Fi names and passwords.

Cleaning

Keep the gateway clean and free from dust to ensure proper ventilation. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or abrasive materials.

Troubleshooting

• No Power:

  Ensure the power adapter is securely connected to the gateway and a working electrical outlet. Check if the Power LED is illuminated.

• No DSL Synchronization (DSL 1/2 LEDs off or blinking):

  Verify that the DSL phone cable is securely connected to both the gateway's DSL port and the wall jack. Ensure no phone is sharing the line without a DSL filter. Contact CenturyLink if the issue persists.
• No Internet Connection (Internet LED off or red):

  Check if the DSL LEDs are solid green. If they are, the issue might be with your ISP's service. Power cycle the gateway by unplugging it for 30 seconds and plugging it back in. If the problem continues, contact CenturyLink support.

• Slow Wi-Fi Speed or Frequent Disconnections:

  Ensure the gateway is placed in a central location, away from obstructions and interference sources (e.g., microwaves, cordless phones). Try connecting to the 5 GHz network for closer devices. Reduce the number of active devices or bandwidth-intensive activities. Consider a factory reset if issues persist after other troubleshooting steps.

• Cannot Access Gateway Interface:

  Ensure your device is connected to the gateway via Ethernet or Wi-Fi. Verify the correct IP address (http://192.168.0.1 or http://192.168.1.1). If you forgot the password, perform a factory reset.
