Was previously on optus cable - no problems. Had NBN for almost a month now, on the 100mb plan, and have done a speed test every day, as I'm not fully trusting of its 'capabilities'
Almost every test (at various times of the day) I get speeds of 80 - 90, but twice (on Saturday mornings) the spped clocked in at 19 and 31.
It all depends on how many people are using the line at the same time.
Fingers crossed the speeds stay high.
