1 – Check your wireless card:
First of all we need to be sure that your wireless card is one of the BCMXXXX-based hardware:

The return should be something like this:
08:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

In that line you can see that my wireless card hardware is BCM4312, so it is supported.

2 – Download the Driver:
You can access Broadcom’s website[0] and download it or use wget to download it through shell.
For 32-bits CPUs:

For 64-bits CPUs:

3 – Remove the other modules:
Check if b43, b43legacy, ssb and/or an older version of wl modules exist:

Remove them, if they exist:

Add b43, b43legacy and ssb to the blacklist, preventing them to be probed in initialization:

4 – Install the wl module:
Extract the tarball you downloaded and compile it, you’ll need to install the build-essential package to compile it:

If you have an older version of wl, which is usually in /lib/modules//kernel/net/wireless, you should rename or remove it, to avoid conflicts:

Copy the new wl.ko to /lib/modules//kernel/net/wireless and install it:

Add it to /etc/modules to load it at boot time:

After these steps your wireless network should be working.

Troubleshooting
I had another problem: after rebooting, ssb module was being loaded even after being blacklisted, and the recently added wl module wasn’t.

To check if this is happening to you run the command below:

If the command returns something, it means that the ssb module is being loaded, then you’ll have to:

1 – Remove ssb and wl modules:

2 – Back up the current boot ramfs, generate a new one and reboot system:

3 – Reinstall wl module:

And wl module will be loaded at boot time.

I knew that aptitude was an upgraded version of apt-get and i’m used to use it, but a i never knew what makes it better than apt-get and never needed to know why, but today, while reading Planet Debian (http://planet.debian.org), i saw Jan Hauke Rahm chatting with dpkg bot (http://jhr-online.de/54), in #debian on irc.debian.org, and at some point of the chat he asks to dpkg: “why aptitude?”,  and it answers:

dpkg > aptitude has more advanced conflict/dependency resolution and will often find a solution where apt-get gives up.  It can be used from the command line like apt-get plus an interactive resolver makes it much easier to recover from broken dependencies.  It has advanced search capabilities (see <aptitude search>.

Thanks to that chat, and the consequent blog post, now i’m enlightened =D.

I chatted a little with dpkg, too, but he wasn’t such a nice bot to me, he asked if i was smoking crack =/.

So i did this:
1 – Connected my Notebook to the 3G Broadband:
Just connected as I normally do.

2 – Connected my PS3 to my Notebook:
Created a LAN between them, through my notebook’s interface eth0.
I configured my PS3′s network connection as follows:
In the PS3′s main menu go to Settings > Network Settings > Internet Connection Settings, then, go through this sequence of choices: custom, wired connection, auto-detect, manual (the ip settings are shown bellow), automatic, do not use (in my case i don’t use any proxy), enable.

The Ip Settings are:
Ip address: 192.168.0.2
Subnet mask: 255.255.255.0
Default Router: 192.168.0.1 (This is my Notebook’s Ip)
Primary DNS: 208.67.222.222 (This is Claro’s primary DNS Server)
Secondary DNS: 208.67.220.220 (This is Claro’s secondary DNS Server)

3 – Set Notebook to IpForward
I found a Script in the internet that does everything it needs to ipforward, all i did was add the final line, which sets a fixed ip to the interface that is connected to the LAN. I don’t remeber who wrote the script, but the credits are his/hers.
All you have to do now is save the script bellow and run it everytime you want to connect your PS3:

If you did as it is described in here, then it should work just fine.

Just for the record, I’m sing BrDesktop Lenny Linux as Operating System (a Debian Pure Blend).

Note: Everytime I try to test the connect through PS3, my notebook loses the ip 192.168.0.1 and starts o search for another one, breaking the connection between them. So i recommend you not to use that feature when using the connection method described in here.

No último Sábado foi realizado o Debian Day 2009 Amazonas, evento que, como comentei em um post anterior, comemora o aniversário da distribuição Debian GNU/Linux.

O evento, na minha opinião, foi muito bom. As pessoas que compareceram ao evento se mostraram bastante interessadas nos assuntos das palestras ministradas, muitas delas me procuraram apóas as palestras para perguntar mais sobre o Debian-AM e sobre o Software Livre em manaus.

Um dos pontos maiores do evento foi a participação do criador e mantenedor do portal Viva o Linux (http://vivaolinux.com.br), Fábio Berbet, que fez duas palestras muito interessantes: “Como gerenciar um site com 8 milhões de acessos” e “Como ingressar no mercado com Software Livre”. Gostaria de deixar aqui meu agradecimento ao Fábio, desejar que o Viva o Linux continue crescendo e que possa leválo até a Espanha! hehehe, Quem estava no evento sabe do que eu estou falando.

Gostaria de parabenizar toda a equipe do Debian-AM, pela realização do evento, e a galera de manaus do Projeto Fedora e o representante do BrOffice em manaus, Carlos Lucoli, e a todos os patrocinadores e apoiadores, que nos ajudaram muito.

Como prometi, está aqui o slide da minha palestra sobre o Projeto BrDesktop:
