    All computers are on the same Wi-Fi.
    All computers used in same locations.
    Samples consistent over several years.
    Network settings the same on each (same DNS servers etc.)

    These are alright
    HP Laptop (i5/8Gb) > 20Mbps
    MacBook Air (i5/8Gb) >20Mbps

    These are hopelessly slow and regularly lag or cut-out
    HP Laptop (Celeron/2Gb) < 2Mbps - a known problem with Broadcom BCM 43142 drivers
    MacBook Pro (i5/8Gb) < 2Mbps

    The MacBook Pro was purchased in 2018. It has no third party software and is used only for Safari, Apple Mail, and Apple Numbers. Why might the MacBook Pro Wi-Fi connection be as slow as it is? (it actually uploads faster than it downloads!)

    Is the MacBook Pro running on wireless ac or 5 GHz?

    How are you testing the download speed?

    Tried resetting the router?

    Is the MacBook performing other tasks while testing? Drive is full?

    Compatibility issue between MacBook and router?

    MacBook Pro is getting a good signal?

    I'm not sure exactly what would be causing the issue.

    Thanks Audit13 - your first response put me on the path to fixing it..

    I don't know if you were two steps ahead or not, but I have now created separate SSIDs for the two bands, which means there can be no opaque automatic switching going on.
