I have a Superhub 3, and up until a three days ago everything has been fine. The connection is fast and has decent ping (~8ms on speed tests) when it is working, but the connection regularly drops out with ping exceeding 100ms and jittering a few hundred milliseconds at a time. It then returns to normal. Every device in the house has been experiencing the same problems, and even when streaming videos the drop in quality is enough to make the video buffer for a minute or so. I can confirm that I have the same problems over wired connections to the router, and at the same time as the problems over WiFi. I initially tried reinstalling my network card drivers and I have restarted the hub multiple times, but these have not affected the experience. I have attached a broadband quality monitor that I already had running (although the ping I experience is worse than the maximum ping depicted) and my hub power levels. Thank you in advance for your time.
So the Ping spikes can be due to utilisation or you max out either or both download and upload and buffer in the hub. So I could say was you idle at the times when the spikes happen but the truth is no one really knows what their connection is doing unless you setup QoS on a router and tested your Bufferbloat. https://www.waveform.com/tools/bufferbloat
Here is my bufferbloat score. I tried QoS a while back when having some other issues, but I did not find it helped. There have been no new devices added nor has there been any change in internet activity - in fact, there has been less usage than normal as my brother who streams high quality video a lot and games isn't here. I highly doubt, especially considering that everything was fine before, that a bandwidth issue is causing my problems. It's 12am as I write this; I'm the only one using the internet and am still having latency issues.
