[SOLVED] Trying to install and work the Broadcom wireless-BMC43142

I'm trying to install and make work the Broadcom wireless-BMC43142

I can't make it work the Broadcom wireless-BMC43142. I've messed up with various installation and activations of various modules and to be sure to start properly I removed every package.
I've search that I need to install the b43 from my device and I don't know witch should I install (b43-firmware, b43-firmware-classic, b43-firmware-legacy).

So on for now I have installed the iw for the wireless network management.

I installed the iw and when I use the iw dev the only I get is blank link, without a message.

I have messed in my head and I follow the wiki anymore. I've looked the following threads and I seams all greek to me.

Please follow the Broadcom page on the wiki. According to the links there your card is not supported by b43, so you may have to use wl.

Just to be sure, could you post the output of `lspci -vnn | grep -i net`

Thanks, as I suspected this card is only supported by the wl driver. But in your output now it shows that the wl driver is in use: is the wirless interface now showing up in your `ip a` output? If not, have you removed and blacklisted b43 and ssb modules as described on the broadcom page of the wiki?

Is tried to install the broadcom-dkms-wl drivers instead the broadcom-wl I've tried now and I think I make the work, since I had the modules already acivated.

Now I see it in the ip link command and now works.

To get this right. First I install the driver of my network wireless card, enable the necessary modules (wl and bcma, in my case) and activate the interface with the ip link (wireless) up?

Yes, but in a majority of cases the first two parts of that are not required: the linux kernel has built in modules for a vast majority of consumer hardware. Your broadcom card is a (current) exception to this which is why you needed to also get the wl driver.
