I have the Huawei HG659 but it has issues if there is around 14 devices connected to it, causing loss of connections and having to disconnect certain devices from wi-fi and restart others in order to try and get them to connect.  This seems to be a common problem and it's also causing havoc with my Sonos system.    Searching for answers I came across this post - https://community.tpg.com.au/t5/Modems-and-Devices/Replacement-modem-router-for-TPG-FTTN-NBN/td-p/128097   I am also a long time TPG customer having been with you for 10 years so I would like to get a replacement modem router also please. Please let me know what I need to do.  Thank you ... View more
