From: https://forum.openwrt.org/t/nftables-and-qos-in-2021/112013/530 =E2=80=9CI literally spent multiple days walking my friend through installi= ng OpenWrt on a gl-inet router, configuring several APs, connecting up powerline networking equipment and configuring cake in 2 or 3 spots on his network (both at the router towards the WAN and across the powerline segments to keep them from saturating). His wife was teaching anatomy classes, needed a camera on her face, a camera on her desk where she was showing images and drawing diagrams, and I think a camera on a microscope. All that just for her. They had something like a 600/60 DOCSIS connection, and in addition to all the interactive teaching she was doing, he was in video meetings all day and both their kids in online school, plus they were living with his parents during the stay-at-home period. so there were maybe 6 or so devices video streaming at any given moment throughout the day. The full download capacity of that internet connection was close to 10x the powerline speed... Expanding to 3 APs, ethernet over powerline, and cake to limit all the bottlenecks including over the powerline (which at best was getting something like 70Mbps reliably...) with Diffserv4 and prioritization and network segmentation and all that stuff... they could seamlessly walk through the house roaming from AP to AP with everyone getting 0 latency issues after a week of configuration.... Before all that work no-one could understand any of her lectures at all and she was literally in danger of losing her job." I imagine nearly every science teacher suffered this way, and few found enough help. --=20 :( My old R&D campus is up for sale: https://tinyurl.com/yurtlab Dave T=C3=A4ht CSO, LibreQos
