Maximum NBN™ wholesale speeds are not guaranteed. There are several factors that can affect your NBN™ speed which are explained in more detail here but they can include:
|Weak WiFi signal||To rule out a weak WiFi signal, you should test your speed on a computer connected to your modem with an Ethernet cable.|
|Damaged or loose cables||Check that all cables are in good condition and plugged in securely.|
|Virus or malware infection||Run an antivirus/anti-malware scan using your antivirus software. If you need a hand with this, please contact your security software’s Customer Support.|
|Firewalls or other antivirus software settings||Test your speed while firewalls/antivirus software is temporarily disabled. Please contact your security software’s Customer Support if you need a hand with this.|
|Data congestion||To rule out data congestion, reduce the number of connected devices on your home network.|
|Network congestion||Test your speed at different times of the day, especially if your slow speeds only seem to occur around 5-8PM, which is a typical time for network congestion to occur.|
This article covers how to do this on iiNet modems supplied for NBN™ FTTC, which you must use with your NBN™ FTTC service.
On a TG-789 Broadband Gateway
On a computer that's connected to your TG-789 Broadband Gateway, open your web browser and go to http://10.1.1.1. After logging in, click the Broadband panel and then click + Show advanced options in the upper right-hand corner. Scroll down to Line rate - the speed listed next to the downwards arrow is your sync speed for downloads.
If your modem has a good sync speed but your speed test results on connected computers are significantly slower, continue to the next step to troubleshoot potential interference on your home network.
Note: There are different kinds of Ethernet cables. We recommend using a Cat 6 or Cat 5e cable. While a Cat 5 cable will work, it may not support the speeds of your NBN™ service.
