Upgrade Broadcom bcm43xx_firmware

Hello, I am curious to know if is there any safe way to upgrade the Broadcom 4311 firmware.

By reading some documentations, I noticed that opensuse 11 is using a custom script to download and install the correct driver from Index of /sources

I was guessing that, perhaps, by editing the script to point toward the latest driver, it would be possible to upgrade.

I.E. (original script) /usr/sbin/install_bcm43xx_firmware:

#!/bin/sh

install_bcm43xx_firmware

This script tries to download and install the firmware needed to run

WLAN cards using Broadcom’s bcm43xx chips.

firmware for b43

URL1=http://mirror2.openwrt.org/sources
FILE1=broadcom-wl-4.150.10.5.tar.bz2
FIRMWARE1=broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o

Modified line:

FILE1=broadcom-wl-4.150.10.5.3.tar.bz2
FIRMWARE1=broadcom-wl-4.150.10.5.3/driver/wl_apsta_mimo.o

Anybody attempted something like this?

Should work, see no reason for it not to

You can modify the script to download and extract the firmware from ANY
Broadcom driver that is supported by b43-fwcutter. I’m not sure what problem you
are trying to solve. My experience is that the firmware from the “standard” file
is as good as any other for the cards that b43 supports.

Hello Larry; nothing to solve, just the idea to update the current driver to a newer release.

I’m not sure the newer driver has newer firmware embedded in it. As long as
b43-fwcutter can extract the firmware, it will work, but not necessarily make
any difference.
