Hi maro:
I tried your suggestion: using b43 driver instead.
I used a vanilla installation, where firmware-openfwwf.tcz is default.
Unfortunately, it still does not work. :-\
Not even the wi-fi led is on!

Dmesg | tail -20 tells us why:
Code: [Select]
EXT4-fs (sdb1): mounting ext2 file system using the ext4 subsystem
EXT4-fs (sdb1): mounted filesystem without journal. Opts: (null)

]b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website .

I'm a little confused, so let me set the record straight:

  • I thought that this firmware-openfwwf.tcz was the info obtained by the b43-fwcutter.tcz, right?
  • If not so, then do I need to fetch additional info with b43-fwcutter-tools.tcz?

I've noticed, that there is another firmware-broadcom.tcz in the repos.  Could that be used instead.?  Are they mutually exclusive?

Your help will be highly appreciated.

Yes - see the linux wireless b43 site for details if required

Hi everybody:

I'm still trying to install the correct firmware for the BCM4312.  But now I feel I'm getting finally there!.

Managed to download and unpack the correct archive (broadcom-wl-4.150.10.5.tar.bz2) that corresponds to the b43-fwcutter (version 012).

But when I try to install the driver to "/usr/local/lib/firmware", I get the following error message:

failed to open file: Read-only file system.


Can I just install it to other directory ( i.e., /home/tc), and then just move all the files to the desired directory?

Then, once, I have all files in the correct directory, how can I keep them there after re-booting?

regards,

cefcom

The files in that location are just links to  /tmp/tcloop/firmware  which is read only. If the filenames
you are trying to copy over already exist there you will get that error.

Don't load the firmware extension if it does not contain the firmware you need.

I finally got it working. Thank-you all! :) :)

This is what I did:
  • Deleted all links in /usr/local/lib/firmware/b43,
  • Extracted all files into /home/tc/b43,
  • Copied (as root) all files in there to the directory in step 1,
  • Unloaded (as root) b43 and ssb from terminal,
  • Re-loaded b43,
  • Opened Wifi and led lighted up, selected network, entered wep-hex-key,
  • That's it!

This is how Dmesg | tail -20 looks like now:
Code: [Select]

wlan0: RX AssocResp from 00:24:17:92:c9:ec (capab=0x411 status=0 aid=1)

The only thing left to do is an extension, to save settings. ::)
