So this Aussie Navy ship that was visiting us lately was putting out
enough power in its navigation radar to cause interference to internet
users and radio reception across a significant part of the country.

says the interference happened specifically on the 5GHz band.

And there is this interesting bit:

    The interference triggered in-built switches in the devices that
    caused them to go offline, ABC News reported – a safety precaution
    to prevent wireless signals interfering with radar systems in New
    Zealand’s airspace.

So there are safety cutoffs inside (at least some of) your wi-fi
appliances, so if radars encroach into a band they’re not supposed to
be using, you get pushed aside?
