Hello!
I have the following wi-fi card on my Dell Latitude E6400:
siba_bwn0 at pci0:12:0:0: class=0x028000 card=0x000c1028 chip=0x431514e4
rev=0x01 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'Broadcom Wireless b/g (BCM4315/BCM22062000)'
class = network
Grepping for 0x4315 I found that my card is supported by bwn driver:
root at olimpico-freebsd 22:08:00 ~ # [0] grep -r 4315 /usr/src/sys/dev/
| grep -i bcm
/usr/src/sys/dev/siba/siba_bwn.c: { PCI_VENDOR_BROADCOM, 0x4315,
"Broadcom BCM4312 802.11b/g Wireless" },
root at olimpico-freebsd 22:08:01 ~ # [0 0]
I have recompiled my kernel (slightly modified 8.1 kernel) with the
following options set:
device siba_bwn
device bwn
device wlan
device wlan_amrr
device firmware
Then I installed bwn-firmware-kmod port and now I have the following
modules loaded:
root at olimpico-freebsd 21:57:25 ~ # [0] kldstat
Id Refs Address Size Name
1 9 0xc0400000 7bde40 kernel
2 1 0xc0bbe000 37248 if_bwn.ko
3 1 0xc0bf6000 2b770 bwn_v4_ucode.ko
4 1 0xc0c22000 2cb24 bwn_v4_lp_ucode.ko
root at olimpico-freebsd 21:57:27 ~ # [0]
These modules were created during bwn-firmware-kmod build using
firmware extracted
from broadcom-wl-4.178.10.4.tar.bz2 by means of b43-fwcutter tool.
I also noticed that bwn0 interface was created:
root at olimpico-freebsd 21:57:37 ~ # [0] ifconfig bwn0
bwn0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290
ether 90:4c:e5:21:44:ec
media: IEEE 802.11 Wireless Ethernet autoselect (autoselect)
status: no carrier
root at olimpico-freebsd 21:57:44 ~ # [0]
My problem, however, is that when I run
root at olimpico-freebsd 21:59:45 ~ # [0] ifconfig wlan create wlandev
bwn0 ssid olimpico wepmode on wepkey 0120119850 weptxkey 1 up
wlan0
root at olimpico-freebsd 21:59:54 ~ # [0]
I see the following in dmesg output:
wlan0: Ethernet address: 90:4c:e5:21:44:ec
bwn_v4_lp_ucode15: firmware image loaded, but did not register
bwn0: the fw file(bwn_v4_lp_ucode15) not found
bwn-open_v4_lp_ucode15: could not load firmware image, error 2
bwn0: the fw file(bwn-open_v4_lp_ucode15) not found
Am I missing something important?
Thanks!
