Consumer-grade Wi-Fi is also a major problem when it comes to latency & jitter. It doesn't even have to be game streaming, any real-time application such as calls suffer from it as well, despite not actually requiring much bandwidth at all.

Unfortunately there is no user-friendly tool to test for this. Most tests focus purely on speed, which can be tricked by various packet-loss-compensation algorithms, so you can score a "perfect" 1Gbps speedtest despite the connection cutting completely for a second.

speedtest.net used to have a sibling "pingtest" site that measured your jitter. I'm not sure why they don't exist anymore.

I remember it using a Java applet. I think the reason none of the online test sites support it is because it’s hard to test latency & jitter in the browser as the lower layers try hard to compensate for it.

Oh. It was Flash.

Sometimes I forget that was ever a thing!

Speedtest for random server (servers listed on Ookla is quite random) is useful but ping for random server is a bit useless. Just ping for targeted server that runs service you use.
