Frankbell, i thought this was one of those forum where they ignore the newbies questions and I did not this forum is well kept. I know you guys are volunteers and i am very thankful for the time, dedication and patience you guys have towards us, newbies. Thank you very much for your help.
The links you have provided me with were the ones I tried first with negative result. The first one
http://wiki.debian.org/bcm43xx, came with an error on the firmware-b43-installer and I couldn't install it. Then i tried the second link,
http://wiki.debian.org/wl, no success. At that point I tried ndiswrapper since I had the win-driver for BCM4312, no success. I came hero to post more to get more help and since I got no answer quick enough I went and did a clean install and tried everything again. Late night I saw your post giving me the links.
Now, at this point is worth mention that I found a solution to this problem. How? Here it is.
When I tried the first link,
http://wiki.debian.org/bcm43xx, and got the same error with the "firmware-b43-install". I left it there and went to the second link to tried it at the installation of 'module-assistant and wireless-tools' the command line told me that firmware-b43-install is partially install and if I want it to reinstall it. Yes, Same error than before. So i used Synaptic to completely remove firmware-b43-installer and followed the rest of the second link,
http://wiki.debian.org/wl, steps. And yes it work I have wireless connections available. I declare this post solve. Thanks, Frankbell.
