Hi @sithco952 ,
Welcome to TPG Community!
The firmware of your router is specialized to work with TPG NBN service, which is why you are unable to upgrade it. Your router currently has the latest firmware.
May we know what is the issue that you are experiencing with your service? If you are experiencing slow speed issues, you may visit an article that we've created to guide you on how to resolve it. Check this link.
Thanks for the information.
We've run a remote test and was not able to detect any fault within the NBN network.
We'll arrange a call from our Tech team to look into it further. Please shoot me a private message with your best contact number and most convenient time to receive a call today.
