I am attempting to enable my wireless interface in Slax Linux, so far, I know the driver I need is brcmsmac, since I have a broadcom card; and this work in Slackware.

The driver is available and does not show any errors when I load it with:

# modprobe brcmsmac

But no new interface is loaded.

Here is I've tried:

# lspci | grep Network

03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

# ifconfig -a

eth0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Any suggestions?

I am sorry @slm, here's dmesg output

# dmesg | grep brcmsmac

brcmsmac bcma0:0: mfg 4bf core 812 rev 24 class 0 irq 16
ieee80211 phy0: brcmsmac: fail to load firmware brcm/bcm43xx-0.fw
ieee80211 phy0: brcmsmac: Failed to find firmware usually in /lib/firmware/brcm
brcmsmac: brcms_bcma_probe: brcms_attach failed!

I hope this help!

Can you show us some output from dmesg after running the modprobe command? Also what does /var/log/messages show after your system boots as far as this hardware goes? – slm Apr 7 '13 at 4:42
Thanks for your advice, I am compiling a Slackware package just now, so I am going to post dmesg output later, gee! I am sorry – slackmart Apr 7 '13 at 5:02
So, I am here again. Help me, please. I've added dmesg output, as @slm suggest me. – slackmart Apr 7 '13 at 23:09

Given the output from dmesg I would suggest downloading the firmware from the broadcom site. Check out that link, there are pretty detailed instructions on how to download and install the firmware that the dmesg error message is mentioning.

general steps

1. download firmware file: http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git

2. copy brcm/bcm43xx-0.fw and brcm/bcm43xx_hdr-0.fw to /lib/firmware/brcm

3. Use the nvram file installed in your system and copy it to /lib/firmware/brcm/brcmfmac-sdio.txt The firmware can be found in the linux-firmware repository.


For 4329: cp brcm/brcmfmac4329.bin /lib/firmware/brcm/brcmfmac-sdio.bin
For 4330: cp brcm/brcmfmac4330.bin /lib/firmware/brcm/brcmfmac-sdio.bin

4. Run modprobe brcmsmac (or something like that)

I may be missing steps but it will be something along those lines. Again consult the broadcom link I mentioned above for further details.

Going to try... – slackmart Apr 8 '13 at 0:12
All is fine now. A little note: since my wireless card is BCM4313, I've skipped the three step. Thanks Sam! – slackmart Apr 8 '13 at 4:13
