Broadcom BCM4312 802.11b/g (14e4:4315 ) driver and issues

[Gia90]

Hi guys,
After reading and trying every solution suggested on the web, I'm here to ask your help to enable this wireless card hopefully without issues.

My OS is BackBox 3.13, which shoud be based on Ubuntu 12.04, and no available driver seems to be working as expected.
Hope you can help me,
Thank you.

Hi, indeed you do have some issues, let's see if
we can get it running. Please open a terminal ctrl/alt/t
then please COPY and paste one line at a time. This must
be done from a wired connection,connected to the internet.
please do, and ignore errors or file not found, do each line.

sudo apt-get update
sudo sed -i 's/^REG.*=$/&IT/' /etc/default/crda #set country code to europe/rome
sudo rm /etc/udev/rules.d/70-persistent-net.rules # names your eth0 and wlan0
sudo sed -i '/^blasklist b43/ d' /etc/modprobe.d/blacklist.conf #removes b43 from blacklist
boot

then let's clean up the wireless..again you must use a wired connection
please copy and paste and ignore errors ,,,

sudo rm /etc/modprobe.d/blacklist-bcm43.conf
sudo apt-get remove --purge bcmwl-kernel-source
sudo modprobe -rf ssb
sudo apt-get remove --purge b43-fwcutter firmware-b43-installer
sudo apt-get install firmware-b43-lpphy-installer
sudo modprobe -rf b43
sudo modprobe -v b43

next..please set your network mgr. IPv4 and IPv6 to look like the attached.

BOOT..disconnect the wired connection and test.

boot

It seems I don't have "boot" installed...
I ignored it and went on with the other commands.

I blacklisted the b43 adding a line in /etc/modprobe.d/blaclist.conf which your commands didn't remove, so I did it manually.
Then rebooted and it seems to be working.

I already tried installing "firmware-b43-lpphy-installer" and it was working till it randomly started to drop internet connection even if it kept connected to the AP with excellent signal.
To make it working again I could only put wlan0 down and then up again, wait some minutes or, eventually, reboot...
I hope your suggested config for ipv4 and ipv6 will help (even if I already tried them without success..).
Btw I will keep you updated on how it behaves.

Another question: Does b43 load the right firmware? I copy/paste from dmesg:

b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)

There are newer ones which (I think) should be more advisable for my os version...

Thank you for your help!!

UPDATE:
The connection drop issue descriped above is still here...
Suddenly web pages stopped loading and it couldn't ping any host.After a while it started working again, at first slowly and then at normal speed.

BOOT means "restart" "ctrl/alt/del" "system restart"
please do a restart and then run and post wild Mans script
file again please.
thanks

Did you run the command to purge bcmwl-kernel-source? The wl module still shows in the report
This is the command from Hadaka's post

sudo apt-get remove --purge bcmwl-kernel-source

Or did this command result in an error?

[Gia90]

Package bcmwl-kernel-source is not installed, so not removed

I think wl is still there cause I previously compiled and installed BroadcomSTA from the vendor site..

I will wait on someone else then as I have not dealt with this on 12.04, but my instinct would be to blacklist wl.
