Even though "man 4 bwn" and "man 4 bwi" list several Broadcom devices,
your particular model 4313 doesn't seem to support those drivers (but
models 4312 and 4319 do). It might be possible to use the "NDIS wrapper"
port to load the "Windows" driver for the device.

This problem has been discussed and, as it seems, solved 5 years ago:

I just downloaded the drivers on my Windows computer,
extracted the driver files, and transferred the necessary
ones (bcmwl5.inf, bcmwl564.sys, bcm43xx64.cat and
bcmwlcoi64.dll, since I am running amd64) over to my
FreeBSD machine using a USB memory stick.

I then had to convert the files to FreeBSD kernel modules
by using ndisgen, however, since one of the driver files
was encoded in UTF-8 ndisgen required converters/libiconv,
so that had to be installed first:

# cd /usr/ports/converters/libiconv && make install clean

All I had to do next was to run ndisgen and follow the
instructions. I should mention that, for some reason, I had
to run ndisgen from another directory than the driver files
were located in, otherwise ndisgen failed to build the kernel
modules.

Once ndisgen had finished I ended up with three .KO files,
which I placed in the /boot/modules directory. I was unable
to load these files using /boot/loader.conf, so I ended up
making a /etc/rc.d script which can be found here. Save the
script to /etc/rc.d/bcm4313 and run:

# chmod a-w+rx /etc/rc.d/bcm4313

Done!

Re-including list, hope that's okay.

Yes, that is correct (at least certain parts of the /usr/src
subtree are needed).

This can easily be done with freebsd-update (which I assume you
have been using to get to 10.3-RELEASE-p7): In /etc/freebsd-update.conf,
make sure you have "src" in the line

Components src world kernel

This will install or update the sources when you run an update.
If I remember correctly, you can perform this as a "partial update"
where only the missing component will be installed.

Hi,

Tried the above steps, successfully converted the files but when I try to
load the .ko driver I get a stackoverflow and the OS reboots pls what do I
do? This has not allowed me to load the successfully converted windows
driver using ndisgen.

Help!!!!!

I cannot find 10.3 kernel source package online.
Start by looking at

I suggest you include more explicit information when requesting help.

You say you tried to "load the .ko driver" you got from ndisgen.

From what I remember, there should have been 3 .ko's generated by
ndisgen, which have to be loaded in this order :

kldload bcm<N1>.cat.ko
kldload bcm<N2>.dll.ko
kldload bcm<N3>.sys.ko

So what exactly are you trying ?

I can not help you beyond a point because I do not have that card
myself. And as I said earlier, Broadcom open source support for its NIC
is virtually non-existent. Perhaps Atheros would have been a better choice.
