We are experiencing persistent internet drop out and exorbitant slow speeds durign the time the connection is up. This has been the case since mid January 2020. I have disconnected the modem to listen for noise on the network and was unable to hear any static. I have disconnected the phone for extended period of time and that hasn't changed the experience.
The actual speeds for ADSL2+ services will vary due to many factors including distance from the local telephone exchange, the quality of the customer's copper phone line, cabling and equipment.
Devices connected by Wi-Fi may experience slower speeds than those connected by Ethernet cable.
There are cases that the actual speed is no longer enough to accommodate the devices and its online activities and it may look like the connection is dropping out.
We'd recommend having a read of this community article, which may help you check if the speed you're getting at the moment is within acceptable range.
This also includes troubleshooting on how the speed can be improved.
In your case, we have identified a line fault causing the connection drop out and slow speed and a Telstra technician will come out to fix the issue.
Let us know if we can be of further assistance.
