My connection is FTTC and i am currently on NBN100 plan. The ping is always close to 10ms in speedtest. I switched my plan from NBN50 to NBN100 but it didn't make any difference. I am using Archer VR1600v router supplied by TPG. I need less than 5ms ping to do certain type of work. Is there anything I can do to improve the ping? Any suggestions would be appreciated.
