What is something that I can make fail, either audibly or visually? Showing my grandmother ping statistics isn't going to work (;-)) Video call over 2.4 GHz wifi, then start the microwave. Glitchtastic every time.
I'm not sure the Linux networking changes help with that (;-))

Joking aside, is there a famously _bad_ video or audio site, one that everyone hates?
Or a setting for a service that makes it fail?
Here's an idea - no clue if it's a good one. Get yourself access to a low bandwidth connection: if the following table is correct (dubious source and video compression always varies depending on content) then you can easily saturate a 10Mbps DSL line with a 4K video: Resolutions Required Bandwidth Required H264 H265 1280×720(HD) 3Mbps 1.5Mbps 1920X1080(FHD) 6Mbps 3Mbps 3840×2160 (UHD) 25Mbps 12Mbps 4096×2160 (4K) 32Mbps 15Mbps (source: https://www.synopi.com/bandwidth-required-for-hd-fhd-4k-video/ in case the table got mangled into unreadability. ) Maybe you have a way to fractionalize your own network connection if you don't have access to 10/1 DSL. With YouTube, you can select the resolution (although it's not very granular at the top end). If you can toggle CAKE on/off, see if the saturated line becomes unsaturated. If not, reduce the video resolution and repeat. YouTube's "Stats for Nerds" may also be helpful? -- Giles https://www.gilesorr.com/ gilesorr@gmail.com
