6.2 Resetting the Router

If you encounter persistent issues or forget your login credentials, you may need to reset the router to its factory default settings. Locate the reset button (usually a small pinhole button) on the router. With the router powered on, use a paperclip or similar pointed object to press and hold the reset button for approximately 5-10 seconds until the indicator lights flash. The router will then restart with factory default settings.

6.3 Cleaning

Clean the router periodically with a soft, dry cloth. Do not use liquid cleaners or aerosols. Ensure the ventilation openings are clear of dust to prevent overheating.

7. Troubleshooting

• No Power:

  Ensure the power adapter is securely connected to the router and a working electrical outlet. Check the power outlet with another device.

• No DSL Connection (DSL light off/flashing):

  Verify the DSL cable is correctly connected to the router and the wall jack. Ensure your telephone line is active. Contact your Internet Service Provider (ISP) if the issue persists.
• No Internet Access (Internet light off):

  Check if the DSL light is solid green. If not, resolve the DSL connection first. Log into the router's web interface and verify your ISP's connection settings (username/password). Restart the router and your modem (if separate).

• Wi-Fi Connection Issues:

  Ensure the 2.4GHz and/or 5GHz lights are on. Check your Wi-Fi password. Move closer to the router to improve signal strength. Try restarting the router.

• Slow Internet Speed:

  Restart the router. Check for interference from other electronic devices. Ensure your devices are connected to the appropriate Wi-Fi band (5GHz for faster speeds, 2.4GHz for wider coverage). Contact your ISP to check your line speed.
