Step-by-Step Troubleshooting

1. Check for Known Outages:
Before troubleshooting, verify if there are any planned or unplanned outages affecting your service:

2. Restart your equipment:
Turn off your modem/router and NBN Connection Box for 2–3 minutes, then turn them back on.

3. Check all cables:
Make sure every cable (coaxial and Ethernet) between the modem/router and the NBN Connection Box is secure and undamaged.



4. Eliminate Interference

Wireless interference can cause connection instability.

5. Test a wired connection:

If you’re using Wi-Fi, plug your device directly into the modem/router with an Ethernet cable to rule out Wi-Fi issues.

6. Contact SpinTel Support:
