I've managed to locate your account and remote tests showed that your internet is now working for almost 9hrs.
Feel free to let us know should you still require further assistance.
Hi @lukeselmes, can you check the speed using only one device directly connected to the modem via ethernet cable?
If it's not possible for you to check the speed via wired connection, please connect only one device to the Wi-Fi and make sure that there are no programs running on the device background so we can get an accurate result.
Please check the speed here: https://www.speedtest.net/
We'll wait for the screenshot of the speed test result. Thank you.
The test result that you've sent is taken using a device that is connected to the WiFi. Do you have any computer that can be connected via Wired for comparison?
This will help narrow down the issue if it's within the WiFi or within the NBN connection itself.
