Frequent Dropouts on NBN HFC

SOLVED Go to solution
Level 2

I live in Qld. I switched from ADSL to NBN in October. Since then, I've been experiencing frequent dropouts. Dropouts happen range from a few minutes to an hour or two. Happens any time of the day/night (not just peak hours).

Even though my PC is connected through WiFi, I doubt the issue is due to WiFi, because the lights on the NBN black box goes out when the dropouts occur. Other than that, the VoIP light from the Huawei modem turns OFF when it happens.

My observation of the lights off sequence from the NBN box/Huawei modem is like this:

1. VoIP from Huawei modem turns off.

2. Four lights from NBN box turns off.

3. Lights slow come back on from NBN box: sequence is Power, DL/UL, online.

4. VoIP from Huawei model comes back on.

Every time the dropouts occur, I have to wait for 5-10mins for that sequence to complete.

I managed to find a log from the modem, showing frequent connect/disconnects with error message: ERROR_ISP_DISCONNECT or ERROR_ISP_TIME_OUT. (see attachment)

I called TPG tech support today and went through some troubleshooting, but still same result. Is anyone experiencing the same problem?

Hi @davchen,

 

I checked the account and learned that the case was already escalated to our Engineering team. A technician visit was booked for 08/Nov/2017 between 8AM - 12PM, to help us with the investigation to identify the cause of the problem. Updates will be given by your assigned engineer.

 

Cheers!

Hi @BasilDV,

 

TPG engineer visited today and apparently the NTD keeps on power cycling. We're now waiting for a NBN engineer to contact us. Hopefully they will replace the NTD and fix the issue. I shall update this post later. Thanks!

Hi @davchen,

 

Thank you for the update. I checked the account and our Engineers are still waiting for the response from NBN Co. Updates will be given by your assigned engineer once there was a schedule for an NBN technician to fix the issue on your NTD Box (Network Terminating Device). Cheers!

A NBN technician has visited today and found out that there are some old wiring out of the house which is causing the problem. He has replaced those worn out sections and it's now working fine.

Thanks so much for the help!
