Any hint?

I just made a fresh install of ubuntu 12.04

At first boot, the network manager showed the wireless card as present but not ready due to missing firmware, and its led indicator was orange.

I installed all the updates, then installed the additional STA and NVidia driver.

Now, after reboot, the STA driver has disappeard from the additional driver and the network manager no longer "sees" the wireless network card.

Could it be that the problem is the STA driver itself? What I should do if this is the case?

I don't know why the card appears and disappears but I am quite sure that the STA driver is not correct. Please do:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree

Reboot and let us see:

dmesg | grep b43

Thanks.

[El-ahrairah]

I've done as you suggested. The command

dmesg | grep b43

gave no output.

I hope I do not have to go through another fresh install...

[chili555]

Please try loading it and then see what the messages might be:

sudo modprobe b43
dmesg | grep b43

Thanks.

[El-ahrairah]

After rebooting now my laptop after a few days away from home, the wireless network card automatically turned on! This is gonna make me crazy...

So, let's try again:

dmesg | grep b43

It seems that this time the b43 drivers automatically loaded, the output was:

[    1.303410] b43-pci-bridge 0000:03:00.0: PCI INT A -> Link[LK4E] -> GSI 19 (level, high) -> IRQ 19
[    1.303422] b43-pci-bridge 0000:03:00.0: setting latency timer to 64
[   23.501404] b43-phy0: Broadcom 4311 WLAN found (core revision 10)

[   23.879066] Registered led device: b43-phy0::rx

[   24.349143] b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07)

And, if it could be of any use:

rfkill list all

Output:

0: hp-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Here I see a new phy0 entry which I've never seen before.

Some other various commands previously requested:

lspci -vvnn | grep 14e4
03:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)

lspci -nn | grep 0280
03:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)

I will now try to reboot leaving the lan cable detached to see if something changes.

[El-ahrairah]

So, I tried rebooting a total of 4 times:
- 2 simple reboots
- 2 complete system shutdown, turning the system on after a couple of minutes

After this 4 tests, all done with the lan cable not connected, the wireless card turned on only once.

I also tried manually loading the b43 module, but nothing changed.

I'll now try a reboot leaving the lan cable connected to see if something changes.



EDIT:

After a few more reboots with the lan cable connected, the wireless remains off, I even tried to put the b43 module in the /etc/modules file but to no avail.

I really cannot understand why it would work only a few times...

Ideas, anyone? Should I go, again, for a fresh install and completely avoid the STA drivers this time?

[chili555]

Please reboot and when it's not working, do:

dmesg | grep -e wlan -e b43 > info.txt
lsmod >> info.txt
iwconfig >> info.txt

Find the file info.txt in your user directory and attach it to your reply using the paperclip tool at the top of the reply box.

[El-ahrairah]

Here you go!

I also tried installing the following two modules using synaptic:
firmware-b43-installer
firmware-b43-lpphy-installer

I obviously tried them one at a time, with some reboots between the two tests, but still nothing changed.

[chili555]

Your thread mentions ndiswrapper, the STA driver and b43 firmware. Of these three methods, two are incorrect. Please do:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get remove --purge ndiswrapper

I even tried to put the b43 module in the /etc/modules file

It is not loaded in your info.txt. Let's look for blacklists:

ls /etc/modprobe.d

Let's check:

cat /etc/modules

Please do not add any new drivers until we can fix this!
