We're on ADSL2+ offnet on Springwood NSW exchange. Over the past month or so, our service has become increasingly unreliable, with frequent "unable to connect" errors and super-low speeds as shown in the test below (conducted with NO other devices connected to the line), especially in peak periods. There appears to be no interruption to the service to our premises, as our D-Link modem shows constant connection (unlike previous occasions where we've had multiple dropouts due to phone line faults) and our account usage stats confirm this.
I know that lines have been/are being upgraded in our area in preparation for imminent availability of NBN, but can't see how this could affect our speeds without affecting the integrity of the connection; therefore, I can only assume that the problem lies in the quality of service being made available by TPG via our Telstra line. This is really not filling me with confidence to take up the NBN via TPG when it becomes available.
Would appreciate it if this problem could be investigated!
