Hi,
I signed up for the NBN when it was connected in my town from day 1 (June 2016). I opted for the 50/20 speed boost through which I was achieving consistent and reliable speeds of around 42/14 even during peak times. I was very happy with this speed and consistency.
However after around 2 months of being connected my speeds dropped overnight to around 26/4. After the usual exhaustive (3 weeks or more) process of telstra support, the issue was deemed to be caused by 'co-existence'. No one could offer me a satisfactory explanation for the sudden drop in speed, even though the techs that I spoke with were telling me that my line rate was still capable of much faster speeds.
Most recently my speeds are consistently around 28/2 (with even slower uploads of just over 1Mbps UP) and my Telstra Gateway is showing me slower max line rates as well. The download speed reduction is disappointing but the upload speeds are what I need improved and are not acceptable for my daily use. I fail to see how 'co-existence' could cause my upload speeds to drop from 14Mbps to mostly 1.5Mbps?
My question is, has anyone else had a similar experience or received a reasonable explanation as to why, on a perfectly capable line, the speed has slowed so dramatically? Is there realistically anything that can be done about the situation?
I am considering starting another ticket with Telstra support but the process is so frustrating with generally the same results.
