Hi @Ruethai, Welcome to the community! There are different cause of Transfer/Speed Issue that you may experience.
Sync Speed Issue, this speed issue is caused by a line fault on TPG (If you're with ADSL2+ or TPG-FTTB) or NBN's network (If you're with NBN service). 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.
Wireless Transfer Rate Issue, 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.
Speed/Transfer Issues, this issue is caused by possible loose modem/router connection setup. This can be fixed by re-seating Ethernet cable if the device(s) is connected via LAN, re-seating the modem/router to the wall socket or changing the phone cable used from modem/router to the socket.
Note: You will need to test multiple speed test when you change Ethernet,Phone Cable to identify the caused of speed issue.
