i may of possible found a fault in some sockets they could or may affect your nbn signal,if you had the old socket that used to be for the wall phones your notice an extension socket you can buy so you can run the ADSL cable to the NBN modem , well my old one i notice two metal strips only on the male side that plugs into the female side,also i notice the hole where the NBN socket from the modem goes in had only two bits of copper wire, where the new one got 4 bands where the hole is where the NBN side goes in from the modem, immediate my speed was a little faster, because there was more copper wire meeting the modem side. its just ten bucks from jb hi-fi or an electronic shop its not a NBN fix but it helps when you notice you got slower speed
