New User - Broadcom BCM4322 issue

[pyro117]

I have just upgraded to the latest version of Kubuntu (removed and old Mac 10.5 OS off the macbook). My first attempt, I didn't have it hard wired as the installer couldn't see the wireless card. I read a lot of articles and tried to install the BCM drivers - no luck, Ndis wrapper - no luck, the STA - no luck.

I am new to Kubuntu (and linux in general). So I probably typed a lot of commands wrong. I then re-installed the Kubuntu instance with the hard-wired connection in place allowing it to upgrade.

This time the wireless card can be seen by Kubuntu but it won't find any networks to connect to. Here is the information about my Broadcom wireless card:

03:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)
Subsystem: Apple Inc. AirPort Extreme
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort+ <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 256 bytes
Interrupt: pin A routed to IRQ 23
Region 0: Memory at 93200000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: wl
Kernel modules: wl, ssb

If I am posting this in the wrong forum, please let me know. I wasn't sure where to post the question.

Possible a bug: https://bugs.launchpad.net/ubuntu/+s...l/+bug/1075407

Otherwise, in a Konsole:

sudo modprobe -r b43
sudo modprobe -r b43legacy

sudo apt-get update
sudo apt-get install b43-fwcutter

That should automatically download and install the firmware and turn on the wireless. Make sure your Mac doesn't have a mechanical wireless on/off switch that got mistakenly turned off. Ditto for a keyboard toggle.

This guidance should still be applicable to your BCM4322: https://help.ubuntu.com/community/Wi...Driver/bcm43xx

[GreyGeek]

As usual, I forgot something...

You should install "firmware-b43-installer", which will run the b43-installer app.
And that will only for for a BCM4322 IF the "lspci" command show the port as given by:
BCM4322 (only 14e4:432b)

I have read through the articles mentioned and some others and found that after the second install (when I had my laptop connected via the internet). The Broadcom STA drivers were already installed. I then went back and found some articles about the STA drivers not auto starting. I looked at the following file:

/etc/modules

I noticed that the wl.ko (the STA drivers, i think) was not in the file. So I found this command that adds it to the file:

echo wl | sudo tee -a /etc/modules

Now when I boot I get the wireless to work.

Thanks for your help.


BTW, anybody know how to stop the KDE daemon from asking for a password? I assume it is asking for this password so the network manager can gain access to my Wireless connections password.

One way: Network Management Settings, Other, Store Connections Secrets: In file (unencrypted)

That avoids kwallet.

You can also just disable KWallet in System Settings/Account Details/KWallet

Got it - thanks!

To my knowledge, the 'b43' driver does not support 4322 chips, so going with the 'wl' (broadcom sta) driver is probably the correct option.

[GreyGeek]

As I said:

And that will only for for a BCM4322 IF the "lspci" command show the port as given by:
BCM4322 (only 14e4:432b)

And that will only for for a BCM4322 IF the "lspci" command show the port as given by:
BCM4322 (only 14e4:432b)

I managed to miss that part. It probably is 432b since it's a/b/g/n capable (I assumed we were talking about 14e4:4322).

Easy to do. I missed a piece of info on another thread and posted info relating to what I thought was a similar sitution. The OP accused me of trying to hijack the thread.
