The default in netbsd-10 and -current is to have powersave disabled.
With powersave you often see latencies of ~100ms.

RPI has a weak antenna, so "other devices" may not be a good reference.

I'd suspect a firmware bug. I should reactivate my RPI3 for a test.

N.B. I don't see issues with a RPI0w, a RPI4 and a BPI M2 Zero
which comes with a bwfm compatible chip.
