Yes, the email said TPG and NBN infrastructure can't be the problem. But TPG tech also tested my house wiring last week, swapped internal lines and put a new outlet socket in. Tech said that basically eliminates my house wiring as the source of the drop outs.
So I don't understand what the problem is ... that has been going on since connection over two months ago.
Regrettably, I wish I was the bearer of better news. Based on the remote testing done by our Engineering Team, all equipment within the TPG network is working and that the current level of service is the best that can be delivered to you on your current infrastructure.
We don’t have any further updates differing from what has already been communicated to you. If you wish to know more details about the fault's case progress, we can have one of our Engineers to discuss this over the phone.
With my hearing there really is no point in phone calls involving new and detailed explanations.
I have emailed back to Engineering and when I hear back I'll pop back and update here, for anyone watching.
After due consideration I accept TPG can't or won't do anything else for now and I'll just have to live with a crippled connection, for now. The drop outs continue ... without knowing why, maybe internal wiring since that seems to be the primary cause of issues with FTTN, but TPG engineering won't comment or advise what to do now.
If the ALP take power this election there is a possibility of a fix down the track, but I won't hold my breath. From here - https://www.smh.com.au/business/companies/no-bells-or-whistles-labor-keeps-it-simple-with-its-nbn-pl... - "Labor would also provide up to $125 million of funding to NBN Co to remedy interference issues with the fibre-to-the-node elements of the network caused by the internal wiring within premises."
If the ALP do get in I will probably get back on here to find out if anything has changed, re article above. The ALP also intend to mandate a Customer Service Guarantee, which I believe I had to relinquish any right to in order to sign with TPG.
