Broadcom WiFi

richardpl · Apr 21, 2010

Read the handbook dude, that should be your first move anyway.

On 8.0 you need to create wlanX first and use wlanX instead of ndisX.

gnemmi · Apr 21, 2010

You should probably read: rc.conf(5), wlan(4), wpa_supplicant(8) & wpa_supplicant.conf(5) .. or section 31.3 of the FreeBSD Handbook

help

help! i'm battling with my brodcom 4315 and ndis bcmwl5_sys driver - it's not going well- i'm unable to run wpa_supplicant freezes, kernel panics if i put module in boot/loader.conf

is there ANYONE with 4315 that can give me a hand? thanks.

richardpl · Apr 22, 2010

Never put module in loader.conf before you test it via kldload(8).

unsobill · Apr 22, 2010

strangeness enough kldload loads bcmwl5_sys.ko without issues - however when i add same module to /boot/loader.conf i get kernel panic...

also i'm not sure if my issue in the driver itself or wpa_supplicant... as any time i try to use wpa_supplicant iÐµ freeze and give me errors such as

Code:

ioctl[SIOCS80211, op 26, arg 0x0]: Operation not supported
Failed to disable WPA in the driver.
ELOOP: remaining socket: Ð¸ Ñ‚Ð°Ðº Ð´Ð°Ð»ÐµÐµ

here is my wpa_supplicant.conf

Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

network={
ssid="Ð¼y AP"
key_mgmt=WPA-PSK
psk="topsecretpassword created from running wpa_passphrase"
}

here is how i run it

Code:

sudo wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf

richardpl · Apr 22, 2010

Regarding panic during boot, problem is already reported, second time in this thread.

For second issue you must use -Dndis switch, I stopped to count this one.

More info you will get using forum search feature.

unsobill · Apr 22, 2010

help please? i got ndis driver bcmwl5_sys.ko - device is broadcom 4315.
when i run wpa_supplicant i get kernel panic

Code:

$ sudo /usr/sbin/wpa_supplicant -Dndis -iwlan0 -c/etc/wpa_supplicant.conf

unsobill · Apr 23, 2010

Can i use different working module/driver for Broadcom 4315 while hopefully current ndis driver being fixed ???

richardpl · Apr 23, 2010

Where is panic output, I don't see it.

Post # pciconf -lv for that card, and I will see what I can do.

unsobill · Apr 23, 2010

Code:

strangely enough i get no kernel panics anymore since i ran update to stable at night

richardpl · Apr 23, 2010

Perhaps you need to use ap_scan in wpa_supplicant.conf because scanning may be tricky with some drivers.

8.0 RELEASE have bug with scanning(net80211 related, reproducible via ifconfig only), it is resolved in 8.0 STABLE and in CURRENT.

unsobill · Apr 23, 2010

here is my wpa_supplicant.conf - perhaps something is missing here?

Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=1
network={
        ssid="mynetwork"
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP WEP104 WEP40
        psk=********************************
        priority=2
        }

richardpl · Apr 23, 2010

What is panic message? Please post full backtrace.

unsobill · Apr 23, 2010

hard to get panic message if keyboard/mouse down and reboot kicks in almost immediately.
similar to this image of kernel - but that's not my picture - i will come back from work and update with exact picture of kernel

unsobill · Apr 24, 2010

Sorry for the wait, just got back from work - here is kernel panic that i get... Thank you much !!!

richardpl · Apr 24, 2010

There is no backtrace, please define your dump device.

unsobill · Apr 25, 2010

how can i do that?

richardpl · Apr 25, 2010

Look in /etc/defaults/rc.conf, make your swap to be dump device.

hermes · Apr 27, 2010

FYI, bwn(4) has been MFCâ€™d to 8-STABLE (and is working nicely with WPA2 over here

). No more need for NDIS.

richardpl · Apr 27, 2010

It is far from stable for me.

chunky_monkey · Apr 30, 2010

This sounds promising. While I was able to load the ndis modules bcm43xx54.cat.ko, bcmwl564_sys.ko and set up and interface and association, my system would freeze on dhclient wlan0.

So I thought I'd try compiling the bwn modules... until I hit:

Code:

[root@machine /home/bwn/net/bwn-firmware-kmod]# kldload if_bwn
kldload: can't load if_bwn: Exec format error

Any ideas on how to fix this?

unsobill · May 1, 2010

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.

hermes · May 1, 2010

@unsobill: Umm, nope. Thatâ€™s actually no longer the way to do it. Instead, just csup a recent 8-STABLE and recompile kernel and world.
