wm0 is a wired driver (you can see what it is for by 'man 4 wm' - Intel ethernet cards). I suspect NetBSD doesn't support the network card on your laptop, most Broadcom wifi cards do not work. but if they do, it is with the 'bwi' driver which requires manually downloading the firmware (as it cannot be legally redistributed by NetBSD), and instructions are in the bwi man page. But that driver is mostly for older cards. I"ve personally replaced the card in my laptop with another one, and previously used a slim USB one, due to a similar issue. Sorry
