Additional Troubleshooting Steps for Telstra NBN Faults
These troubleshooting steps go beyond basic fault-checking and help improve your Telstra NBN connection stability and performance.
1. Check Telstra’s Network Status Page
🔹 Before troubleshooting, visit Telstra’s Service Status page or use the My Telstra app to check for known network outages or maintenance.
🔹 If there’s an outage, Telstra will typically provide an estimated time for resolution—this saves time by confirming whether the issue is on their end.
2. Restart Your Devices Regularly
🔹 Power cycling your modem and router can help resolve minor connection issues caused by software glitches or overheating.
🔹 How to restart properly:
- Turn off your modem/router and NBN connection box (if applicable).
- Wait at least 5 minutes before turning them back on.
- Allow a few minutes for the devices to fully reconnect to the network.
3. Upgrade Your Hardware
🔹 Old or incompatible modems/routers may cause connection issues, slow speeds, or frequent dropouts.
🔹 If your device is more than 3-5 years old, consider upgrading to an NBN-compatible modem/router.
🔹 Ensure your device supports Wi-Fi 6 for better speed and efficiency, especially in households with multiple devices.
4. Use a Wired Connection
🔹 Wi-Fi can be unstable due to interference, walls, and signal range issues.
🔹 A wired Ethernet connection (using a LAN cable) provides a more stable and faster internet experience, especially for activities like:
- Streaming in 4K
- Online gaming
- Video conferencing (Zoom, Teams, etc.)
- Large file downloads/uploads
5. Monitor Peak Usage Times
🔹 Internet speeds tend to slow down during peak hours (typically 7 PM – 11 PM) due to high demand on the NBN network.
🔹 If you experience slow speeds only at night, congestion is likely the cause.
🔹 You can:
- Run a speed test during different times of the day to compare results.
- Consider upgrading to a higher-speed NBN plan if congestion is a frequent issue.
