Welcome to the Community!
ADSL2+ and NBN speed varies with contributing factor that may affect the speed and there are factors outside of an ISP's control.
Your newly upgraded plan is configured on the TPG NBN100 speed tier with typical evening speed of 66.2Mbps. We expect speeds on this plan outside of these hours to be on par or better as there are typically less active users on the network at other times. Of course this is not a guarantee of speed and as previously stated there are many factors that can impact on speed and performance.
We have dedicated, experienced support and engineering teams to assist in diagnosing and resolving any technical issues related to a customer connection.
