There is no iwmfw module.


Can you show us how you are trying to load the iwm firmware (when
built as a module) and what does dmesg -a | grep iwm say then?

Given you are not providing any error message but an obviously loaded
iwm driver it is hard to say where your actual problem is.

If you are using iwm(4) you need to detach that, disable it, or not
laod it in order to try iwlwifi.  And for loading iwlwifi and the
appropriate firmware please see the thread from yesterday here.
If you are not doing it from loader but rc.conf iwlwifi will pick up
the appropriate firmware by itself.

It'll highly likely be helpful to split your problems up into "iwm is
not working please help" or "I am trying to use iwlwifi please help"
and we'll probably be able to help you solve both.
