The nbn™ network is designed for super-fast broadband. But even on the fastest network, speed issues are possible. Is your nbn™ service performing slowly? We’ve got a few troubleshooting methods to help you solve the problem.

First, take a look at this list of 8 Factors that Can Affect Your nbn™ Experience. The answer to your speed issues might be found in this blog post. While there are optimal speeds you can generally expect from nbn™, your overall experience will vary based on a huge variety of factors. Once you’ve assessed the factors above, go ahead and try our troubleshooting options.

1. Complete a Power Cycle

The most basic fix for nbn™ speed issues is to perform a power cycle. All you need to do is shut off your modem at the wall. Wait for a period of 5 minutes then turn everything back on again. This is a kickstart action that can refresh your connection and have it working up to speed.

2. Complete an Isolation Test

If the power cycle didn’t fix your speed issues, try an Isolation Test next. To accomplish this disconnect all equipment from the phone sockets within your premises. This includes all phones, modems, faxes, splitters and filters.

Leave this equipment disconnected for approximately 15 minutes. Then, plug the modem directly into the main phone socket. Re-test your Internet connection and see if the speed problems have improved.

If your speeds are fixed when the modem is connected directly to the main phone socket, your speed issue may be with the splitter or the phone line itself.

This didn’t solve the problem? No worries. Leave the modem in isolation and complete the next test.

3. Complete a Speed Test

The final troubleshooting test for your nbn™ speed problems is a Speed Test. To perform this, connect your modem directly to your primary computer using an ethernet cable.
