802.11ax (Wi-Fi 6) when is it worth updgrading to ax routers

Devices with 866Mbps link rate before MU-MIMO activation drop to 580Mbps, sometimes to 433mbps with MU-MIMO. Don’t know why. So for the small eventual benefit MU-MIMO provides to some devices other devices actually slow down.

Another little secret widely known by industry insiders, but by few consumers, is that Broadcom's 2x2 MU-MIMO client-side devices fall back to 1x1 mode when connected to a MU-MIMO enabled router. This happens with both Qualcomm and Broadcom-based routers; the problem is on the client side.
