Ever since I got connected to NBN(HFC) 3 weeks ago with TPG(25/5), my latency has been terrible. My ping while gaming on ADSL2+ was 19ms and now I'm constantly getting 80 - 150 - 250ms during peak time. Download speed is still good however it's almost impossible to play any game from 6pm - 12am.
Rang TPG to ask if I could switch back to ADSL2+ but was told I can't and I should upgrade to 100/40 plan. I'm skeptical as to if this will make a difference.
What should I do ?
I have yet to hear of an ISP that actually says "We didn't buy the bandwidth to allow all the customers we take money from to have an internet connection that works as advertised".
So I'd just go straight to TIO with the aim of changing ISP's at no cost to you. Why waste your money and time because they're happy that you do provided you keep paying them.
