good morning,
Late last night I tried to install 13.1 on my old laptop. Long story short, I installed the wrong driver (b43-fwcutter & firmware) when I needed (broadcom wl). Using yast to uninstall the driver (b43) & Installing the correct driver over the previous did not work. Any suggestions other than re-installing.
lspci indicated bcm4321.
John
You mix something up here.
The firmware is no driver. It is loaded by the b43 driver to make your device work.
If you don’t use the b43 driver, it doesn’t matter if that firmware (or b43-fwcutter which is just a program to extract the firmware out of a binary driver) is installed or not.
Please post the output of “lspci -nnk”. There is more than one bcm4321 device.
And how did you install the wl driver?
If it’s the package from Packman, make sure you installed “broadcom-wl” and “broadcom-wl-kmp-xxx” (where xxx depends on your kernel).
“broadcom-wl” prevents the b43 driver from loading, if you don’t install it wl cannot be used because your card is already in use by the b43 driver.
rpm -qa | grep broadcom
uname -a
Installing ‘wl’ will blacklist b43 assuming you did properly

Thanks

packages installed:
Broadcom-wl
Broadcom–mw-kmp-default
I see one that says desktop, is that what I want to install, and uninstall -default?
Thanks
You’re using kernel-desktop, but have installed the driver for kernel-default, therefore it doesn’t work.
Remove broadcom-wl-kmp-default again (and kernel-default, which is also installed most likely) and install broadcom-wl-kmp-desktop.
sudo zypper rm kernel-default broadcom-wl-kmp-default +broadcom-wl-kmp-desktop
or use YaST for that.
ok I did that & rebooted. now I show:
Broadcom-wl
Broadcom-mw-kmp-desktop
Still no wireless.

Please post the output of “lspci -nnk | grep BCM4321 -A3”, that shows which kernel module is in use.
And please post again, which kernel you are using (“uname -a”).
What does the file /etc/modprobe.d/50-broadcom-wl-blacklist.conf contain? If it doesn’t exist, you have to re-install “broadcom-wl”.
sure: here is the output:

Please try
su -
modprobe -rv b43
Can you try the steps outlined in https://forums.opensuse.org/showthread.php/494525-Enable-Broadcom-BCM43142-in-OpenSuse-13-1
I’ve noticed that you have the Broadcom device that matches the STA drivers and I’ve been able to enable wireless on my Dell laptop.
You can remove any broadcom-* RPMs before you start, just to have everything cleaned up, also make sure you have all the dependencies ready:
zypper in make gcc binutils kernel-source
Please let us know how it goes for you!
Sorry, but I can’t really see how compiling the exact same driver himself would work better than using the RPM packages.
Especially as his system doesn’t even load the wl driver.
I think it should be:
su -
modprobe -rv b43-pci-bridge
but I’m not sure. Maybe try both.
And afterwards try to load the wl driver manually:
modprobe wl
Then post the output of this please:
dmesg | tail
lspci -nnk | grep BCM4321 -A3
Another idea:
You can configure which kernel module to use in YaST’s Network Settings. Maybe this somehow is configured explicitely to be “b43”?
If that’s what causes b43 to load despite of the blacklist, then the above procedure should work.
Enter YaST->Network Devices->Network Settings, select your wireless card and click on Edit. Then switch to the Hardware tab, that’s where you can select the kernel module, set that to “wl”.
And you should better switch to Network Manager for wireless on the “Global Options” tab.
ok tried all that, some of the command produced no output, 1 produced an error. I bolded the commands.

I also ensured the wireless is on in the bios. The FN-F2 key switch turns the light on and off. I know it worked before I put 13.1 on it (windows).
thanks again.
You made a typo there, therefore there’s no output. It should be “lspci”.
Maybe the modprobe worked and the wl driver is in use now? I see no error in the dmesg output at least.
I just spotted that typo too, I just checked and its the same output as before:

No wireless in network manager or iw config.
in network manager in yast, the edit button is greyed out an un-clickable.
also rebooted again, no change
thanks
Well, did you run that lspci after the modprobes and before you rebooted, or after the reboot?
It’s clear that after a reboot everything is like it was before, since that modprobes didn’t change anything in your system’s configuration.
In Yast the Edit button is greyed out if NetworkManager is running, that’s normal in this case.
Switch to “ifup” on the “General Options” tab, “Edit” your wireless interface and set the kernel module to “wl” and reboot.
Please post the “lspci -nnk | grep BCM4321 -A3” again then.
Maybe this would get “wl” loaded?
This was the correct code
thansk john
I think the device died (see last line): If you agree, would you know if I can put any wireless into a laptop (I have another dell that ran opensuse fine until the monitor dies, that wireless is a broadcom also)
