How to Troubleshoot NBN Connection Issues at Home or Work
Is your NBN connection constantly dropping out, running slower than expected, or showing no signal at all? Whether you’re working from home, managing a business, or just streaming your favorite show, a poor internet connection can be incredibly frustrating. The good news? Many common NBN issues can be identified and resolved with expert help—and that’s where CGC Sydney steps in.
As Sydney’s trusted telecom specialists, we’ve helped hundreds of homes and businesses fix their internet issues fast. Here’s what you need to know.
Common NBN Issues
Before diving into fixes, it’s important to identify the type of issue you’re facing. Some of the most common NBN problems include:
• Slow or inconsistent internet speeds
• Modem/router not syncing with NBN
• No internet despite being connected
• Dropped Wi-Fi signal throughout the property
• Connection dropouts during peak hours
These issues can stem from faulty internal wiring, outdated modems, poor placement of your router, or even problems with the NBN infrastructure itself.
Step-by-Step Troubleshooting
Here are a few steps you can take to troubleshoot your NBN connection:
1. Restart Your Modem and Router
Sometimes a simple reboot can resolve temporary glitches. Power off your modem and router, wait for 60 seconds, and then turn them back on.
2. Check Cable Connections
Ensure all cables are properly connected and undamaged. Loose or frayed cables can interrupt the signal and reduce speed.
3. Run a Speed Test
Use tools like Speedtest.net to check your internet speed. Compare it with the plan you’re paying for to see if it matches.
4. Try a Direct Connection
Connect your device directly to the modem using an Ethernet cable. If the speed improves, the issue might be with your Wi-Fi setup or router placement.
5. Check for Local Outages
Visit the NBN Co website or your ISP’s support page to check for planned maintenance or outages in your area.
