Uso ubuntu da 3 anni e questo ha consentito al vecchio vaio vgn-sz del 2005 di sopravvire perfettamente performante (mai arrivato alla corda, accensione in 15 secondi, spegnimento in 7) con il solo aggiornamento da 1 a 3gb di ram, hd da 160 a 250, una batteria (cinese durata pochissimo).
Oggi è arrivato il dell latitude e6400 (euro 400)

ovviemente vista ha preso il volo in pochi secondi.
In attesa di montare un hd da 500 gb 7200, non voglio spingermi molto in la con l'istallazione su questo da 80.
Appena arrivato il pc ho provato il live 10.04 direttamente da hd usb, tutto ha funzionato da subito tranne il wifi, una brutta e conosciuta bestia.....: Broadcom Corporation BCM4322 802.11a/b/g/n.
L'avevo istallata 2 gg fa nel pc di Matte, un hp di 4 anni fa, che aveva ancora su ubuntu 8.
Comunque detto fatto, connessione lan, google ed ecco la soluzione dal sito di ubuntu community documentation:
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
nel caso le rimuovessero, ma non credo, eccola qui sotto:
Identifying Your Card/Driver
In a terminal the command lspci will display information about all PCI devices attached to your computer.
To display only devices manufactured by Broadcom (including wifi cards), apply a filter for "14e4" as follows:
~$ lspci -vvnn | grep 14e4
The following is an example of the information required to identify your card type and typical lspci output.
- CHIPSET - BCM4322
- PCI-ID - [14e4:432b]
Note: the PCI-ID is of particular importance.
03:00.0 Network controller [0280]: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)
Unsupported cards
If you are unable to use the b43 kernel driver or the b43/STA hybrid driver, you will need to go for ndiswrapper - this will allow you to use closed source drivers to activate your wifi card.
Installing b43/STA hybrid drivers
9.10 (Karmic Koala), 10.04 (Lucid Lynx), 10.10 (Maverick Meerkat)
Supported models, mostly found on Dell hardware, include:
BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225
b43/STA - Internet access
Step 1.
Install the b43/STA hybrid drivers/firmware from the restricted repository using the Software Centre or the Synaptic Package Manager (Under the desktop menu System > Administration > Synaptic Package Manager) and search for the bcmwl-kernel-source package and install or in a terminal (under the desktop menu Applications > Accessories > Terminal) issue the following commands:
~$ sudo apt-get update ~$ sudo apt-get install bcmwl-kernel-source
Step 2.
Under the desktop menu System > Administration > Hardware Drivers, the STA drivers can be activated for use.
Note: A computer restart may be required before using the wifi card.
LiveCD/LiveUSB
For temporary use with the LiveCD and LiveUSB environments, simply use the Software Centre or the Synaptic Package Manager to search for and install the bcmwl-kernel-source package. Refer to Step 1 and Step 2 of the instructions above.
Step 3.
Instead of a computer restart, in a terminal issue the following commands:
~$ sudo modprobe -r b43 ssb wl ~$ sudo modprobe wl
Note: Allow several seconds for the network manager to scan for available networks before attempting a connection.
b43/STA - No Internet access
If you do not have any other means of Internet access on your computer, you will have to install the bcmwl-kernel-sourcepackage from the restricted folder under ../pool/restricted/b/bcmwl on the Ubuntu install media.
Step 1.
Navigate the install media and double click to install or navigate the install media and install these packages consecutively in aterminal (under the desktop menu Applications > Accessories > Terminal):
../pool/main/d/dkms
:/dkms/$ sudo dpkg -i dkms*
../pool/main/p/patch
:/patch/$ sudo dpkg -i patch*
../pool/main/f/fakeroot
:/fakeroot/$ sudo dpkg -i fakeroot*
../pool/restricted/b/bcmwl
:/bcmwl/$ sudo dpkg -i bcmwl-kernel-source*
Step 2.
Under the desktop menu System > Administration > Hardware Drivers, the STA drivers can be activated for use.
Note: A computer restart may be required before using the wifi card.
LiveCD/LiveUSB
Note: The install media contents are mounted under /cdrom of the filesystem.
Step 3.
Instead of a computer restart, in a terminal issue the following commands:
~$ sudo modprobe -r b43 ssb wl ~$ sudo modprobe wl
Note: Allow several seconds for the network manager to scan for available networks before attempting a connection.
Installing BCM43xx drivers
8.04 (Hardy Heron), 9.10 (Karmic Koala), 10.04 (Lucid Lynx), 10.10 (Maverick Meerkat)
Supported models include:
BCM4301 BCM4306/2, BCM4306/3, BCM4311, BCM4312, BCM4318, BCM4320
The Ubuntu kernel in versions 8.04.x (Hardy Heron) and higher do provide the b43 drivers, however due to copyright restrictions not the proprietary firmware which is required to run your card. See here for a list of known PCI devices and their available modes as well as supported/unsupported chipsets.
The following instructions explain how to extract the required firmware.
b43 - Internet access
If you have some other kind of Internet access on your computer, you can download the firmware by simply installing the b43-fwcutter package which does the download and setup for you automatically.
Step 1.
To install b43-fwcutter issue the following command in a terminal (under the desktop menu Applications > Accessories > Terminal) and follow the prompts:
~$ sudo apt-get install b43-fwcutter
Step 2.
Under the desktop menu System > Administration > Hardware Drivers, the b43 drivers can be activated for use.
Note: A computer restart may be required before using the wifi card.
LiveCD/LiveUSB
Step 3.
For temporary use with the LiveCD and LiveUSB environments, instead of a computer restart, in a terminal issue the following commands:
~$ sudo modprobe -r b43 ssb ~$ sudo modprobe b43
Note: Allow several seconds for the network manager to scan for available networks before attempting a connection.
b43 - No Internet access
If you do not have any other means of Internet access on your computer, you will have to install b43-fwcutter and patchpackages from the install media. After that you will need to setup firmware manually (without the firmware automatically downloading and being set up).
Setp 1.
b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under../pool/main/p/patch/ or both in the official repositories online.
Double click on the package to install or in a terminal (under the desktop menu Applications > Accessories > Terminal) navigate to the folder containing the package and issue the following command:
:/b43-fwcutter/$ sudo dpkg -i b43-fwcutter*
Step 2.
On a computer with Internet access, download the required firmware files from http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o and http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
Step 3.
Copy the downloaded files to your home folder and execute the following commands consecutively in a terminal to extract and install the firmware:
~$ tar xfvj broadcom-wl-4.150.10.5.tar.bz2 ~$ sudo b43-fwcutter -w /lib/firmware wl_apsta-3.130.20.0.o ~$ sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o
Step 4.
Under the desktop menu System > Administration > Hardware Drivers, the b43 drivers can be activated for use.
Note: A computer restart may be required before using the wifi card.
LiveCD/LiveUSB
Note: The install media contents are mounted under /cdrom of the filesystem.
Step 5.
For temporary use with the LiveCD and LiveUSB environments, instead of a computer restart, in a terminal issue the following commands:
~$ sudo modprobe -r b43 ssb ~$ sudo modprobe b43
Note: Allow several seconds for the network manager to scan for available networks before attempting a connection.

per il resto sembra funzionare tutto, dai tasti del volume alla regolazione della luminosità.
Aspetto però il nuovo hd per un test più approfondito.
