Vodafone nbn® connection troubleshooting guide
This support article will assist you with common Vodafone nbn® connection issues.
From time to time there may be planned maintenance by nbn® or unforeseen incidents that may cause an outage. Check out the nbn® website for maintenance updates and network outages.
Initial troubleshooting steps
If you’re unable to connect to Vodafone nbn® using your Vodafone Wi-Fi Hub™, TP-Link VX420-G2H or compatible modem, try these troubleshooting steps:
Turn your device off at the plug.
Unplug all cables then reinsert them into the correct ports. If you have FTTC, FTTP or HFC, make sure the ethernet cable is plugged into the red port labelled ‘WAN’ on your Vodafone Wi-Fi Hub™ or TP-Link VX420-G2H. If you have FTTN or FTTB, make sure the nbn® telephone cable is plugged into the port labelled ‘DSL’ on your nbn® connection device. These cables should make a faint clicking noise when correctly plugged in. You may have a spare cable in your modem box.
Wait 2 minutes and turn on the device. Wait for the internet light to turn solid or flashing green – this may take up to 15 minutes.
If you’ve tried these steps and still can’t connect to the nbn® network, please give us a call when you’re at home on 1300 801 122.

You’ll know when the nbn® network is active when the ‘internet’ light is activated and the ‘LTE’ or ‘4G’ light has turned off.
If your Vodafone Wi-Fi Hub™ or TP-Link VX420-G2H does not switch back to the nbn® network, you may be able to manually switch it back. There may be an issue with the nbn® connection device or the modem. If you follow these options and still haven’t reconnected to the nbn® network, please give us a call on 1300 801 122. Our team can then troubleshoot and arrange an nbn® technician if required.

Slow connection speeds
Connection speeds through the nbn® network will vary. There are many factors that affect the speed you'll receive.
If you're experiencing slower than usual connection speeds using your Vodafone Wi-Fi Hub™, TP-Link VX420-G2H or compatible modem, here are some troubleshooting steps.
Run a speed test
Head to the Speedtest website on your device and follow the prompts. It's best to test your speed at different times during the day.
Switch between the 2.4GHz and 5GHz signal
5GHz will deliver faster speeds but has a shorter range than 2.4GHz. Try using the 2.4GHz signal on some devices and others on the 5GHz signal.
Run a speed test again
Head to the Speedtest website again and follow the prompts to see if the speed improves.
Still experiencing slow speeds?
There may be an issue with your connection to the nbn® network. Connect your computer to the Vodafone Wi-Fi Hub™, TP-Link VX420-G2H or compatible modem with an Ethernet cable and run a speed test again using the Speedtest website. With the results, use live chat on this page and we can investigate.
