SOLVED :Mint12 lets me connect ones by Wifi and then no more

Post by meandyesi » Wed Mar 28, 2012 5:42 am

To be able to use Wifi with Mint12 a found in the forum that I had to install the following;
bcmwl-kernel-source
b43-fwcutter
firmware-b43-installer
which I did and immediately I was able to configure and use the wlan0 connection.
So far so good, but after shutting down and later logging in again Mint12 seems to be unable to recognise the wlan0 no more.
Hereafter I give the output from mintWifi :
-------------------------

I had the identical problem with Mint11 although Mint10 gave no problem at all with the same hardware.
Any help is much appreciated.

Regards.

You actually installed two drivers, STA (bcmwl) and b43. Installing them both does not make sense. For Broadcom to work you need either bcmwl-kernel-source or the b43 packages (b43, b43legacy or b43-lpphy) - not both STA and b43.

Each driver supports different Broadcom cards. The STA driver does not support your BCM4306 card, but b43 does (however for old revisions you need firmware-b43legacy-installer). Please uninstall the driver as it might be blocking b43. You can purge the bcmwl-kernel-source package in Synaptic Package Manager.
After uninstalling that package, I think the wlan0 interface will come back.
If it still says firmware missing when clicking the network icon, you probably have an old revision that needs firmware-b43legacy-installer to be installed.

Thank you for the swift reply.
Unfortunately after removing the bcmwl-kernel-source and keeping firmware-b43-installer and b43-fwcutter the wlan0 is still nowhere to be seen.
Further searching the www I came across a site mentioning that in the new kernel the b43-fwcutter no longer finds what it needs...
What still puzzels me is that the very first time I installed all 3 the packages things were OK only to disappear at a new login ?

Regards.

The b43 packages work immediately but bcmwl only becomes active after a reboot. That's what happened.

Probably the file blocking b43 (I'm looking up its name) which was installed by bcmwl, is still present. This happens sometimes when uninstalling it.
I'll lookup the filename and post a command to remove it.

This is the description of bcmwl-kernel-source, making clear that it's not for BCM4306:
This package contains Broadcom 802.11 Linux STA wireless driver for use with Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-based hardware.

Please run this command to remove the blacklist file made by the bcmwl package:

Code: Select all

sudo rm /etc/modprobe.d/blacklist-bcm43.conf
After that b43 should be working again.

I did what you proposed and this is the result :
sudo rm /etc/modprobe.d/blacklist-bcm43.conf
[sudo] password for owner:
rm: cannot remove `/etc/modprobe.d/blacklist-bcm43.conf': No such file or directory
On the www I also read that no longer the blacklist can be manually altered.
Further help is still very much appreciated.
Regards.

Please run lspci -k and look for the "Kernel driver in use:" or "Kernel modules:" text under the Broadcom wifi card.

Following your directions and searching through appropriate files in /etc I noticed that indeed something much needed ( bcm4306 ) was been blacklisting although I could not alter it.
Therefore I reinstalled Mint 12 and immediately went for the two b43 files and indeed now all is OK and the wlan0 keeps coming on after booting and stays that too.

So this is SOLVED thanks to your help.

PS:

I will be looking for this issue to get the label SOLVED, but so far I don't know yet how to do just that.

Besides the fact that I love Mint ( using it since version 9 Gnome,Xfce, LDE, ... ) I now had the pleasure to experience the wonderfull help of the forum, just marvelous.

You can edit the first post to change the topic title.

By the way if you want to change system files you need root access. You can run sudo nautilus from terminal to open a file manager with the right permissions.

Yes I use gksudo Nautilus but in this case its was mentioned that the subject file was autogenerated and not to be edited manually.
Nevertheless all your comments were to the point.
