Ports collection and drivers

I have a weird question -- I just installed FreeBSD on a new machine and I'm using a WiFi card that I pulled from another machine. When I installed FreeBSD on the old machine the installer saw the card and I was able to use it from install forward, but I installed ports at the time. The new machine I did not install ports because I decided to grab the latest via cvsup but it only saw my ethernet card. The machine does see it though because I've found it in pciconf.

Thoughts?

Code: 
$ pciconf -lv
hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'BCM4312 802.11b/g LP-PHY'
    class      = network
mskc0@pci0:9:0:0:	class=0x020000 card=0x02aa1028 chip=0x435411ab rev=0x13
 
wblock -- yeah I was working on that last night, I'm not in front of my PC right now so I can't give the exact messages (I will later).

But I did compile bwn into my kernel, I added it into my /boot/loader.conf I can see bwn0 in ifconfig but I can't configure it. When my machine powers on I see a message along the lines of
Code: 
bwn0: can't load fw (some more specific text here) file

Before I left for work I found a post (which I'll add when I edit this later) that told me to download some files and recompile, which I'll try.

This driver requires firmware to be loaded before it will work. The net/bwn-firmware-kmod port needs to be installed before ifconfig(8) will work.

Taken from bwn(4).
 
Hmm. I thought there was a pkg-message that told what to do with those ports. Please notify the port maintainer.

Anyway, those ports build kernel modules with the firmware. The right one of those modules has to be kldload(8)ed for bwn(4) to work. (How to know which one is right? Try one and look at the output in /var/log/messages. Error messages will be shown if it's the wrong firmware.)

Thanks wblock, I let the maintainer know and I'll try this when I get home tonight and post my results.

To use the kernel module created in net/bwn-firmware-kmod, you will need to load the module:
Code: 
# kldload ssb
# kldload bwn_v4_ucode
# kldload if_bwn

or in /boot/loader.conf:
Code: 
bwn_v4_ucode_load="yes"
if_bwn_load="yes"

Note: If you are a LP (low power) PHY user, use the bwn_v4_lp_ucode module instead.

These instructions worked for me

to get ur card working follow this...

1) Install the siba driver
go to:

http://svn.freebsd.org/base/head/sys/dev/siba/

pick the the files there and put them in /usr/src/sys/dev/siba <- must create
it !

then go to:
http://svn.freebsd.org/base/head/sys/modules/siba_bwn/
pick the Makefile and put in /usr/src/sys/modules/siba_bwn <- must create too.

then:
Code: 
cd /usr/src/sys/modules/siba_bwn
make && make install

2) Install the bwn driver
Similar to 1), go to:

http://svn.freebsd.org/base/head/sys/dev/bwn/

pick the three files there and put them in /usr/src/sys/dev/bwn <- must create
it !

then go to:
http://svn.freebsd.org/base/head/sys/modules/bwn/

pick the Makefile and put in /usr/src/sys/modules/bwn <- must create too

then:
Code: 
cd /usr/src/sys/modules/bwn
make && make install

3) Install bwn firmware:
Code: 
cd /usr/ports/net/bwn-firmware-kmod && make install clean

4)Add the following to /etc/rc.conf:
Code: 
network_interfaces="AUTO"
wpa_supplicant_enable="YES"
wlans_bwn0="wlan0"
ifconfig_wlan0="WPA DHCP"

5)and /boot/loader.conf:
Code: 
if_bwn_load="YES"
bwn_v4_lp_ucode_load="YES"
Note that, depending on your card, you may have to use the non-lp module bwn_v4_ucode_load="YES", but not both.

Now reboot and you should be online.

After all of that work I ended up being so fed up with the poor Broadcom performance I removed the card and went and got another.
