Hey BasilDV, Thanks SO much for getting back to me. (Couldnt get through on the phone due to wait times). I tried what you suggested (I'd already tried that about a hundred times but I gave it another shot nonetheless)  :)  Still doesnt work. I've attached a photo of the NCD. All lights are on but no internet. As mentioned, it worked fine right up until Friday afternoon - the EXACT same time my neighbours NBN also stopped working. And we both share the same pit on the street. Suspicious hey. You mentioned that your assessment of the DPU isnt getting any power. Interesting. I was under the impression that the DPU is powered FROM my end of the connection (by my NCD). Is that not the case? My neighbour (not TPG) has heard from his ISP and they said they have heard of connection mis-mapping whereby my NCD is no longer paired to my address? Something about if the exchange end (or whatever is on the other end) somehow doesnt have my NCD mapped to my port then it wont authenticate and hence wont allow any handshaking. So if there was another new NBN connection somewhere near me that meant some config was altered to support said new connection then the engineer might have screwed something up and ruined mine (and my neighbours) pairing (as it USED to work fine). He also said his ISP, whilst debugging the problem, reckoned they could ping his NCD. However he had totally disconnected it to test this fact (even sent them a photo of it disconnected). Soooo, its like somewhere in the network it thinks my NCD isnt where it is and someone elses might be where it thinks mine is. (This is not the droid you are looking for kinda stuff).  :) Im sure these things arent actual hardware issues - can we get an NBN engineer that knows the process to check the config/mappings/etc? Im sure the next step is to send someone out. But I dont think that will resolve anything except to show that its not something on this end.  ;)  So yes - if you could escalate this that would be brilliant!!! (As I often work from home and I cannot do this now without an internet connection). ... View more
