Vias and free pads do not pick up the (new) net assignment if they are not
directly connected to a component pad. Stitch vias would be an example.
Otherwise the Update command previously described should update free vias.

While that page does describe a process for recovering a file from gerber,
it does not give the most efficient way of doing so.
The process I would use is to start with free track and pads brought in
from gerber. (vias are plotted the same as pads, so they import as free
pads.) Save that file separately. I would then place the footprints so that
the pads overlay exactly. It is also possible to recreate a footprint by
copying the pads (through the clipboard) into a footprint (in the library
editor). Then I would delete all free track and pads. I would then import
the net list or run Update from the Schematic. Then I would open the
separate file with track and pads. I would use global edits to delete all
footprint pads, typically they would be different sizes from vias or free
pads. When I have the file with only track and free pads, I would use Tools
Convert to change all the free pads to vias (or those which are
appropriate, if there are other free pads on the board). I would then copy
this en masse to the PCB with the footprints. It will help if the block
copy reference is in the same location as a footprint pad. When a block is
copied, the default is that copied track and vias and pads pick up the net
from already-existing primitives
I haven't tested this recently; if the net assignments are not complete,
the Update Free Primitives process should complete it.
