Hi Santos
I think you may have to add a  blacklist  boot code to your bootloader:
Code: [Select]
blacklist=bcma,ssb,b43

Hi Santos
I figured that from this:
Code: [Select]
b43-phy0: Broadcom 4312 WLAN found (core revision 15)
I think you may have to add a  blacklist  boot code to your bootloader: ...
Sorry, I got that backwards, you do not want that boot code. That's only needed if you use  wl-modules-KERNEL.tcz
which is not available for TC12. You will need to use  b43-fwcutter.tcz  to get the firmware yourself as mentioned here:
http://forum.tinycorelinux.net/index.php/topic,20402.msg127094.html#msg127094

Instructions for "cutting" the firmware can be found here:
http://linuxwireless.sipsolutions.net/en/users/Drivers/b43/#Other_distributions_not_mentioned_above

Skip the part about building and installing fwcutter, you have an extension available.

Follow the instructions labeled:
Quote
If you are using the b43 driver from 3.2 kernel or newer:

Change step #1 to:
Code: [Select]
mkdir -p package/usr/local/lib/firmware
export FIRMWARE_INSTALL_DIR="package/usr/local/lib/firmware"

Continue with step #2 through #4.

Add step #5 (you will need squashfs-tools.tcz installed):
Code: [Select]
mksquashfs package b43-firmware.tcz
Place the extension in your  tce/optional  directory.
Add  b43-firmware.tcz  to the beginning of your  onboot.lst  file.

Done. :)

Thank you for confirming it worked. Unfortunately that firmware is not redistributable, so each user that needs it has
to  "cut"  it for themselves.
