    Is Orthogonal Frequency-Division Multiple Access (OFDMA) enabled on all AX Routers in both ways, like uplink and downlink between Router/AP and client devices on both bands?

    No, not at all. Only very select routers with specific firmware.

    Select routers such as and on what plattforms (Qualcomm, Broadcom) if so why not as standard on both bands then?
    And what chipset (Qualcomm, Broadcom) has that support on both bands and the clients has to support (OFDMA) it as well?

    Please read the article linked above.
    OFDMA support has problems on both platforms. There are problems with getting OFDMA to show the promised benefits of higher multi-STA total throughput and lower latency. But the larger problem appears to be compatibility problems with older legacy devices that have not had driver updates. Some devices don't understand the new information in beacon frames, so they either don't associate at all or don't stay associated.

    There are more problems with 2.4 GHz devices than 5 GHz, but both bands have problems. Routers makers are very reluctant to enable OFDMA and break their customers' Wi-Fi.

    So in other words the same sh*t like we see with the MU-MIMO, much is promised but delivers very little.

    Yep... and another feature that can have benefit in certain use cases, but generally...

    And yet, they are pushing hard for these benefits in advertising for their routers!
