Actually installing a .tar.gz. Broadcom BCM4312


Sorry if this sounds stupid, but I'm new. I found out ( By reading other posts on here) that I need a driver to work with my Broadcom BCM4312 Network Connector on my Dell Inspiron 1525 Laptop. I have already extracted the tarball, but I don't know what to do to actually install the driver. I am running Ubuntu 10.04.1 LTS, with Windows dual booting.

Thank you if you help,

Ray

Can you tell us what you read that lead you to the conclusion that you should take this approach? If not can you tell us exactly what you downloaded and from where?

I suspect the driver is already packaged for Ubuntu 10.04, so you shouldn't need to play around with tar balls. See for example http://ubuntuforums.org/showthread.php?t=1266620

And finally can you please post he output of the following commands
Code:
lspci | grep net
lsmod | grep b43
find /lib/modules -name b43.ko
iwconfig
Cheers,

Evo2.

Dear evo2,
I came to this conclusion after looking on some posts (Although I was not a member when I found it, so I can't find it again
-_-) So for that, I am sorry. I will switch over to Ubuntu right now and save all the outputs from the commands.

Dear xandercage,

I am not currently able to connect to wireless, but I will be able to soon... So right now I am trying to get it done without a connection.

Thanks,

Ray

Okay, so here are the outputs for those 4 commands:

lspci | grep net:
Code:
09:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8040 PCI-E Fast Ethernet Controller (rev 12)
lsmod | grep b43:
Code:
b43              163523   0 
mac80211         205146   1  b43 
cfg80211         126517   2  b43,mac80211 
led_class        2864     2  b43,sdhci 
ssb              38671    1  b43
find /lib/modules -name b43.ko:
Code:
/lib/modules/2.6.32-24-generic/kernel/drivers/net/wireless/b43/b43.ko
iwconfig:
Code:
lo        no wireless extensions. 

eth0      no wireless extensions.

               Retry  long limit:7   RTS thr:off   Fragment thr:off 
               Power Management:off
There you go! The driver I am trying to install is:hybrid-portsrc-x86_32-v5.60.48.36.tar.gz
I got it off of Broadcom's Website.

Hi,

it seems you already have the driver installed as part of your kernel and the device is recognized (output of iwconfig shows wlan0).


Although it seems I didn't suggest the correct argument to grep in the lspci command. Could you try the following just to confirm what the device is?
Code:
lspci | grep -iE 'broadcom|wireless'
The only thing that you may be missing is the firmware. To find out if you have it installed you can search in synaptic, or perhaps on the command line do something like:
Code:
dpkg -l '*b43*'
I think the package that you want should be called something like firmware-b43-installer

Are you able to get this machine on the net using the wired ethernet? If so you might find that easier than having to boot back and forth between Ubunutu and Windows while trying to get the wireless up and running.

As far as I can tell you should not need to download/install anything directly from the broadcom website.

Evo2.

When all else fails, read the instructions.

Okay, here we go:

lspci | grep -iE 'broadcom|wireless':
Code:
jetso@jetso-laptop:~$ lspci | grep -iE 'broadcom|wireless' 
0b:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
dpkg -l '*b43*':
Code:
jetso@jetso-laptop:~$ dpkg -l '*b43*' 
No packages found matching *b43*.
I hope this helps. I think the latter means that the firmware is not installed. Would the firmware have come with driver I downloaded, or do I need to download a seperate thing?

Thanks,

Ray

See the link in post #8, the official ubuntu.com instructions that will answer all your questions. b43 is *not* the correct driver for your card in Ubuntu 10.04, and must be removed (modprobe -r) for your card to function correctly.

Dear Snowpine,

Okay, so do these directions mean that I need to download the bcmwl file, put it on a cd, then install it through synaptic?

Cutted and pasted for your reading pleasure:

Quote:
Installing b43/STA hybrid drivers

9.10 (Karmic Koala), 10.04 (Lucid Lynx)

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 Synaptic Package Manager and search for the bcmwl-kernel-source package and install or in a 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 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 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

Back to top

b43/STA - No Internet access

If you do not have any other means of internet access on your computer, you will have to install bcmwl-kernel-source package from the restricted folder under ../pool/restricted/b/bcmwl on the Ubuntu install media. This may be done in the following manner depending on the installation media used:

CDROM/DVD

Step 1.

Install the bcmwl-kernel-source package using the Synaptic Package Manager. First select Add CD-ROM from the edit menu to enable the install media as a package repository, then click on Reload to refresh the available packages list, ignore any internet/download errors. Now search for the bcmwl-kernel-source package and install.

Step 2.

Under the desktop menu System > Administration > Hardware Drivers, the 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 Synaptic Package Manager to search for and install the bcmwl-kernel-source package. Refer to Step 1 and Step 2 of the CDROM/DVD 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

Okay, so after some thinking, I realized what the instructions were telling me. I inserted the disc I originally used to install Ubuntu, and loaded synaptic. I went to where you said Edit>Add Cd-Rom. When I did this, every time, even though it was in the computer, it said "E: Failed to mount Cd-Rom" So after trying that a thousand time, I just went to the location of the bcmwl file on the disc. When I got there, it showed the bcmwl file, as a .deb, which I know is easier to install. When I clicked install in looked like it was installing it, when An error message and alot of lines of code popped up saying that it was already installed. Thinking that it actually was already installed, I went to Hardware drivers, hoping it would show up, but it didn't. This is getting very frustrating for me, so it probably is for you too, and for that, I'm sorry.

Okay, Xandercage:

These instructions are for someone with ethernet, which I do not have . I'm sorry, but I don't (and can't) have ethernet for up to another week. Do you know of any way to get it without ethernet? Thanks,
