Hello. I currently I have a N300 Wifi Gigabit modem router, supplied by TPG some years ago, connected to my NBN FTTN service. The modem is getting pretty old now, and I continually suffer NBN service slowdown with spinning circle, and sometimes even dropouts. To rectify, I typically have to reboot the modem which fixes the issue for a period of time. What needs to be done to get a replacement modem, that is more up to date please?
Thanks in advance.
