Smile Broadcom BCM4312 wireless not working in Debian


Hi,

I am not getting wireless in my laptop. I am using Dell vostro 1520, with Debian Lenny Installed. How could I make it working. Kernel version is 2.6.26-1-686

lspci output

Code:
08:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
0e:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
Heard that from 2.6.xx version onwards, support for this driver is included. What should I do? Also I have some questions to ask.....

1) Even if driver is no there, whether lspci shows the the hardaware information with name?


Please help

The driver is there but you still need the firmware. Take a look at bcm43xx - Debian Wiki - http://wiki.debian.org/bcm43xx

Have you got "Fast Ethernet Switching" or something similar set in the BIOS?

This disables one nic if the other is set up (to save power). Unset it if you have

That thread is 4 years old. Why didn't you use the wiki link? I have a Broadcom 4306 card and the wiki instructions have always worked fine for me.

See the recent thread started by LQ member "kamon".

I wonder if the wiki mentioned above is a comprehensive tutorial including the option of using the windows driver with NDISwrapper? (I would check for myself, but I don't have a horse in this race.)

EDIT: kamon thread here: http://www.linuxquestions.org/questi...-linux-804957/

Hello,

This is the thread pixellany is referring to. In the meantime I've found some mentioning that that specific NIC should work with b43 but cannot try it out for myself. I only got it working in the past using NDISwrapper.

Kind regards,

Eric

Broadcom, b43/ b43legacy devices

The modules using this firmware are
b43 b43legacy
To install the firmware
apt-get install b43-fwcutter
You can confirm you have installed the firmware by checking for the following files

* /lib/firmware/b43/b0g0bsinitvals5.fw
* /lib/firmware/b43/b0g0initvals5.fw
* /lib/firmware/b43/ucode5.fw


The sidux manual has a nice page on how to install the firmware if the computer you are using can't get online.
sidux Manuals - Hardware and Graphics Drivers - http://manual.sidux.com/en/hw-dev-hw...-free-firmware

They even have a nifty script that will tell you if you need firmware and what it is.

I think Xavier was referring the thread linked in the OP. It's last post was just over two years ago.

The "kamon" thread is recent.

Exactly - there are a few commands in the linked thread that are unnecessary and could even introduce unneeded complications.
