Re: Buffalo/Broadcom wireless N card

I'm trying to compile support for a wireless router into FBSD 7
using instructions off a FBSD help page I can't locate just now.
(I'm working on building a network bridge.)

none0@pci0:0:10:0: class=0x028000 card=0x03531154 chip=0x432914e4 rev=0x01 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'BCM43XNG 802.11n Network Adapter'
class = network

When it boots in the machine which has the card (I compiled
on another computer) it blows out with a kernel error (writing
not a non-existent page, I think) when the device shows up.
It shows as device bge0 but identified as BCM 5701 (iirc).

Can someone point me in the right direction? Has anyone
gotten this card to work?

With help from the List I got this to work:

The answer, maybe not the BEST answer, but the answer that
works, is to use the Windows XP driver and FBSD's 'ndis'. My
goal was to build a FBSD router with wireless access to my COTS
wireless router to provide network access in another part of the house.

Get the driver files (.sys & .inf) either from the CD that came with
the card or from the Buffalo web site:
http://www.buffalotech.com/support/downloads/

Then, per instructions from the Handbook (11.8.2)
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/config-network-setup.html
run 'ndisgen' on the driver files:

# ndisgen netg300n.inf cbg300n.sys

A .ko file will be generated: cbg300n_sys.ko. It can be loaded
using 'kldload ./cbg300n_sys.ko' but I wanted it loaded at boot.
So, as 11.8.2 says, copy this file to /boot/modules and add the
following line to /boot/loader.conf:

cbg300n_sys_load="YES"

Also, as I wanted WPA encryption, I added two other lines to
loader.conf:
wlan_ccmp_load="YES"
wlan_tkip_load="YES"
The wireless setup instructions are in the handbook section 29;
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-wireless.html

Then in /etc/rc.conf add this:
ifconfig_ndis0="WPA DHCP"
The device 'ndis0' is created by the ndis driver when it handles a
Windows driver. I guess if you have more than one Windows
device and driver you get to sort out the various ndis0/1/2/3/4/5/etc.
If you don't want WPA just use "DHCP" and you don't need the
two extra lines above in loader.conf.

For WPA you need to create the WPA config file:
/etc/wpa_supplicant.conf:
network={
ssid="<your wireless network name>"
psk="<your personal access key>"
}

Somehow, it all magically started working. (No doubt due to the
hard work of many FBSD coders.)

I hope I didn't leave out any major part. I'm posting this not only
so other can benefit if they run into a similar problem, but in case
this box burns (HD fails) I'll have a record of what I did to recreate
it. <g>

Thank you again to those that helped.
