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.
