I am sad to know that the D-Link modem/router did not connect to your TPG NBN. Do you still have the supplied TPG modem/router? If so, you may use it to access the internet while waiting for the repair/refund.
Contacted the Tpg technical and they were unable to fix the connection issue and they referred me this post I hope they talk to D-Link and also remove this router from their recommended list,
I am now left in limbo and because of lockdown in Sydney cannot take it directly to the place of purchase for repairs or refund.
Unfortunately, it would appear that this router does not play well with TPG for some reason. I didn't go as far as getting my account reset, but I did change my password as it was quite short and had been in place for some time. This didn't work either though.
I was never able to get the router to accept my TPG login and password when setting it up manually, so there may be something to that. I don't know if there is a minimum character limit expectation (or character exclusion) set in the login process.
I was able to get the router to connect on a couple of occasions using the wizard but it was never stable and dropped out.
I like many of you bought the D-Link DIR-X5460 based on TPG recomendations on their site. I rang support. They couldnt do anything. So I just reported them to the ACCC based on the below website. My partner works in telecommincations and if they get enough complaints then TPG will start being monitored under ACMA watchdog which will start to cause them grief. If TPG can state in their website "Our team has tested the following modems. Those with a tick are recommended for optimal use on our NBN Home Superfast or NBN Home Ultrafast plans." and I purchase a mdoem based on that recommendation, then they need to fix it with better support or pay me for my modem. I have two months to go with TPG on a contract because we moved but after 10+ years with the company I will be moving on to someone who actaull cares about their customers. Please report them if you have had issues.
I was able to confirm that our Network Engineering Team, successfully tested the DIR-X5460 on our NBN services.
it is possible that D-Link may have made firmware and/or hardware changes to the model we tested that may have resulted in this problem.
Our team will coordinate this with D-Link for further investigation, we'll provide an update when it becomes available.
