Slow NBN connection Speed

Level 3

I have an NBN connection performing poorly. Upload speed hovers around the 18 - 20 Mbps range. Download speed is an amazing 0.5 Mbps.


I've performed a couple of speed tests and occasionally can get 1.5 Mbps.


I've tried restarting both the NBN box thing and the TPG supplied router. I've tried physically connecting to the router also. I've unplugged every device but my laptop. Nothing seems to make a difference.


Could you do some tests on your end and make sure it's all good?


Last time I had this issue I had a large number of images trying to sync to the cloud, but I'm not doing that this time. If you're able to see, can you tell me if there's any large upload or downloads on my connection that might be causing an issue?

Level 3

I've received no replies from anyone, but the speed seems to have improved over the course of the day.


I'm now getting 12 Mbps which, while 24 times better than yesterday, is still just below the minimum acceptable speed for the NBN 50 plan I am on (


I'm still very interested in a technician taking a look at our connection or letting me know about any ongoing network issues.



Hi @Jeremy


We have been notified by NBN Co and it appeared that the issue was caused by a scheduled activity as part of a program of work being implemented into the HFC network to assist with the facilitation of the DOCSIS3.1 software update.


During this work, technicians will be replacing the Band Pass Filters (BPF) at designated HFC exchanges as a pre-requisite for the software update.
During this scheduled outage, each user will be completely offline for 5 minutes or less. Following the work, all users are expected to automatically re-connect to the network.


At the moment, it already shows that your modem is connected for almost 4hrs. Should you still experience issues with the connection, let us know so we can have someone from our Technical team to contact and perform troubleshooting along with you.

Thanks for the reply Smiley Happy

I'm not sure the maintenance accounts for all the difficulties I've been having recently, but it does seem to be on the mend today.


I'll keep an eye out and let you know if it required further investigation.


Thanks for the update, 


We're glad to hear that connection's fine now, @Jeremy
