    Hi,

    I've got a 13" TouchBar MacBook Pro, and just this morning when I connect a External Hard Drive over USB, my WiFi seems to be unusable? It slows down and has on at least one occasion, disconnected from the WiFi altogether?

    I've so far only tried the left hand back USB-C port, and I am using a 3rd Party USB-A to USB-C adapter. Haven't had a chance to try the official Apple adapter yet.

    I remember reading about this happening when people first got their MPB's, but I don't recall if it was ever fixed or not?

    I have the latest Release version of Sierra - 10.12.2

    Cheers
    Stewart

    Edit - Only seems to be when I use my 3rd Party NoNDA adapter.

    Try connecting the drive to the RIGHT SIDE of the MacBook, then get back to us.
    Any difference?

    Change your wifi to 5GHz. Or wrap your adaptor in tin foil.

    I'm currently on a work connection, so no access to the WiFi settings. Guess I will use my Apple adapter for my USB 3.0 Hard Drives≥
