HFC Modem power cutting out

Level 2

Hi, my HFC modem (Arris CM8200) has been regularly completely cutting out, with no lights displayed on the front. The power often won't turn back on for a long period of time when I unplug and replug in the power cable to try to reset it. I'm not sure if this is a power supply issue, but it is becoming quite frustrating.

What steps should I be taking/who should I contact to deal with this issue?





Hi @bokchoybrendo


There are different types of dropouts that you may experience:


1. Network dropouts, this dropout is caused by a line fault on TPG or NBN's network. Affecting all device(s) LAN/Wireless connected to the modem/router this may require a real-time test and investigation by our Technicians and Engineers.


2. Wireless dropouts, this issue only affects the device(s) connected via Wi-Fi which can easily be fix by doing adjustment to the modem/router's settings.


3. Dropouts caused by ongoing outage in your area. 


In the event that you experience dropouts via Wireless/Wi-Fi connection, we recommend having a read on the following articles:

The best way for us to check the status of the line is real-time or when you are experiencing the issue.
