how does mesh wifi work and how is it different from old school extenders?

Also worth noting: Repeaters are even worse. They repeat the signal between you and the original AP, which reduces the throughput by 1/n with n being repeaters plus end device and increases latency by factor n. With repeaters you’re talking to the original AP directly, but your message needs to be passed along several times.
With extenders and mesh you’re talking directly to the approximately closest device. It itself will then send on its own request, be it by cable or by WiFi, which will increase latency, but in and of itself not decrease throughput. If the extender/mesh supports two separate frequencies, it can talk to you on one and the original AP/next hop on another so it won’t interfere.
