Hi Hannah,NBN provide layer 2 connectivity, ISP's provide layer 4 IP services. I can see the issue being deeper in the network than my router and its peer, so restarting my router will have little effect as proved by my restarts over the weekend.AGL's speed test records 49ms of jitter, this should be 30 or less.I tried Chat, but the virtual assistant ran out of ideas and now looking for a Human to take up the thread.
