I recently upgraded to NBN 50 from the basic 12/1 NBN package. Everything was fine before but since upgrading I have been experiencing frequent connection problems - particularly on my smart TV. Sometimes it complains of not being connected when I launch an app... other times with something like Netflix or YouTube it will say that it has lost the connection after a couple of minutes or I might just see the infamous Java spinning wheel on the screen (showing me that it is unable to stream the data fast enough).   As I said, I never had this problem before and have had it frequently since upgrading to NBN 50. Is it possible that I need a newer modem to really take advantage of the higher speeds available to me? My current modem is the AC 1200. I can achieve 50/18 on my PC according to speedtest.net, but for some reason I can't sustain a connection to the TV for very long before something goes wrong. Same TV as before, everything in the same physical location as before...   TIA. ... View more
