Wlan in PClos connection problem


Ok... when I boot pclos and open network centre, my wlan network is already highlighted, however when I try to connect I get a connection failure. Now if I run the rmmod -f b43 in the terminal window and re-open network centre, my network is not highlighted, and when I select it and connect, it is successful... every time.

Is there a reason for this, or can I enter some script that will run every-time before I open NC, ensuring a connection, I realize this would be a workaround and not ideal, but I can't find what's wrong.

Hi,

Looks like unloading the b43 module (or eventually not loading it at all) solves your connection problem.

Then, add "b43" to the file /etc/modprobe.d/blacklist. This way, b43 will not be loaded by default, so you'll always have a working connection.

... it didn't like that, lost my wlan access (only Ethernet, good ol ethernet ) came back when I # the statement. Where does the mod b43 live, or get installed to?, I am downloading the command line book, but what does the '-f' do?

That's weird. Removing the module during its operation fixes the connection but not loading it at all breaks wlan. Ok, I guess you run rmmod -f b43 everytime you want to connect to wifi then.

b43 is a kernel module. If you are running a generic kernel, b43 will probably be part of a kernel-modules package and b43 is loaded at boot.

To know more about the command (or any other command), the man pages are usually a great place to start:
Code:
man rmmod

... that's how one uses 'man' thanks aragorn. I will learn more about the kernels and see if I can find the problem. The OS (PcLos 2016)is operating under 32 bit, so there might be some incompatibilities there... plod on McDuff

Oh, does the kernel get automatically updated each time I use Synaptic Package manager, or is this a separate update?

No, not each time. But if you have set automatic updates on your system, then once in a while when there is an updated version of your kernel, the system will either update the kernel during regular system upgrade or it will ask you if you wish to update the kernel, depending on how you set up things.

I guess you can also look for updates once you are in Synaptic and decide if you wish to update or not.
