problem with ubantu 10.04 and broadcom BCM4306 Drivers
 

I have installed the broadcom drivers but the wifi doesn't see my router. Are there new drivers for the broadcom cards? The light shows that the wifi is active.

This thread should help you get the troubleshooting started.

Let us know the output of some of the diagnostics, particularly the specific chipset, then post the results here, making sure to enclose them in "code" tags, which become available when you click "Go Advanced" down there at the bottom of the Quick Reply window.

TY Frank for your reply
 

This is the chipset

I installed the drivers. The wifi light is on. But doesn't see the router.

Installed the driver, but did it successfully install the firmware? I've seen cases where with no firmware the LED would still light. Wrong, but it happens.

If there are errors, should be listed there.

hi Goumba,
I tried it and got no errors
charles@charles-desktop:~$ dmesg | grep bcm
charles@charles-desktop:~$

Try using

For the Broadcom BCM43XX wireless cards you need to install the firmware-b43-installer and the b43-fwcutter packages:
http://askubuntu.com/questions/55868...s-card-bcm43xx
I did not even bother uninstalling the bcm-kernel-source package as it says there. Perhaps it was automatically uninstalled when I installed the b43 packages since I do not have it on my Lubuntu 12.10 system at present.
Those 2 b43 packages were all I need to get my Broadcom BCM4311 working.

To make sure the driver is installed and running, post the output of:
The aptitude command should show an "i" next to the firmware-b43-installer and the b43-fwcutter packages, and lsmod should show the b43 driver is running.

Running dmesg as root doesn't change it's output, but root privileges are required for viewing other logs.

That's the way it's done. The b43 kernel module is usually included in the kernel package, but the firmware must be installed manually usually from a non-free repository (I forget what this is called on Ubuntu).

Usually when the module attempts to load, and no firmware is present, there will be errors about not being able to find the firmware in the kernel log.

Not sure what I am looking for. On that link you posted It didn't say for Ubuntu 10.04. Do you think I should update? Would that help?

As I said, you do not need to run dmesg as root. Although it doesn't really hurt, output is the same either way (a point of contention among some that logs should only be visible to root, so this may change in the future).

I think TroN-0074 made a typo there, it's supposed to be grep.

Regardless it should have displayed a message about missing firmware with the command I gave you. Run this:

And you should be set. The fwcutter package alone will not install the firmware.

I ran the code and here are the results not sure what it means.

I know there is a firmware directory and it has a folder b43 in it but there is no installer there. I haven't used command lines since CPM years ago. just starting to learn the Ubuntu commands
TY Charlie

Goumba I tried it with the correction grep corrected I got---
charles@charles-desktop:~$ sudo dmesg | grep bcm
[sudo] password for charles:

Same as before.

Are there any files in /usr/lib/firmware/b43, or it it empty. If successfully done, you should see files like ucodeX.fw, where X is one or more digits.

Make sure you have all repositories enabled, like universe and multiverse (you can do this in Synaptic Package Manager: Settings -> Repositories, or add those two words to the end of the deb line in /etc/apt/sources.list), run:

then try it again.

keys_46,
Since Ubuntu 10.04 will reach end of life in April https://wiki.ubuntu.com/Releases perhaps you would be better off just doing a clean install of either Ubuntu 12.04 or 12.10, since the newer versions of Ubuntu will likely have better Broadcom driver support than 10.04 had.
Are you sure you are running Ubuntu 10.04? To be sure that you are, post the output of:
It will report back what version of Ubuntu you are using.
