Wireless Broadcom doesn't function

[nick85x]

Hello guys,
I'm so excited for this new operating system (Linux), I come from Windows OS, but now I'm really satisfied.
Please have patience with me, because I'm still learning the basics of Linux.
I have a small/big problem. The wireless does not work.
I followed this little guide (which also corresponds to the one mentioned, but to no avail) :
http://community.linuxmint.com/tutorial/view/796

Because it corresponds exactly to my wireless card:
04:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
that is to say:
sudo apt-get install firmware-b43-installer
gave error, then I gave:
sudo apt-get install firmware-b43-lpphy-installer
and now he seems to see the wifi card, based on what iwconfig says:
wlan0....IEEE 802.11bg..ESSID : off/any
..........Mode:Managed..Access Point: Not-Associated...Tx-Power=0 dBm
..........Retry long limit:7...RTSthr: off...Fragment thr: off
..........Power Management: on
I also gave him:
sudo lshw -C network

I copied the complete answer of dmesg in dmesg.txt and is uploaded here: http://www.fileconvoy.com/dfl.php?id...cddbd722747744
My computer is an Hp pavilion dv4-1190el and I installed Linux Mint 14 Xfce 32bit all codecs (so it's an ubuntu like)(I use Mint because unbuntu, doesn't starts, all release, lots off error, I don't know why, anyway).
Thanks in advance, best regards.

This may sound crazy but did you try rebooting after installing the package? You may have installed the driver but it won't load until you restart sometimes.

Thanks, "mamamia88", but the rebooting was the first think I have done.

To show you, I tryed:
ciao@HP-Pavilion ~ $ dmesg | grep Broadcom

What you think happen if i give this:
sudo apt-get install pciutils
sudo update-pciids
update-pciids fetches the current version of the pci.ids file from the primary distribution site and installs it. This utility requires curl, wget or lynx to be installed.
Because I found it written that a person who has launched sudo update-pciids then after some time had problems with the wireless device and also with others devices.
For me, this here is the last resort. I do not know where else to go beat my head. Please be understanding for me.

Thanks in advance.

For "Artificial Intelligence": Where I can go? I had open a thread on linux mint forum, but no one helped me, answered. For me, this here is the last resort. I do not know where else to go beat my head. Please be understanding for me.

It's a standard message when the mods are moving threads.
You're welcome to use our forums, but note that non-ubuntu issues/questions are going to be posted in our 'Other OS/distro Talk' forum.
