I had Telstra NBN FTTC installed about 2 months ago. Everything was great and every time I checked speed test I was getting 100mbps download and 18mbps upload speeds constantly. It’s been awhile since I checked my speeds but I randomly checked it at 2am in the morning and was surprised at my upload speed being decreased more than half. I even restarted NCD/modem and checked speeds throughout the day to see if anything changes but still the same issue. 100mbps download and 5mbps upload speed. Does anyone know why the sudden drop in upload speed? Am I being throttled to my old cable plan? Is there a way to fix this as this is not what I am paying for at all?
