I have been here before with similar problems but recently it has been worse.
After recent NBN work outside my home, about two weeks ago, my DL speed has dropped to around 30Mbps . Something wrong there, as my modem wifi droped out very offen. My friends said recenlty optus had changed some of the old modem for their customer due to NBN updated.
Can you do something about this please? ID:6433858
