WIFI issues Broadcom

Postby tyatyi on Tue Nov 20, 2012 11:57 am

Hello dear All,

I am absolutely lost and I would like to ask advise. After upgrading my Broadcom WIFI driver stopped working.
I tried ndiswrapper with a windows driver, I also tried activating the driver as in previous comments, I tried also different distributions, but the driver is not active and wifi is not working. My expert friend also blacklisted the driver and reactivated, but no change.

These are the details:
Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

It shows : wireless disabled by hardware switch. However I triple checked and the physical switch in ON. I switched ON/OFF not working. On some distros it is not even showing this, it just not showing any wireless options.
Else : networking works fine from ethernet cable and 3G stick.

I freshly reinstalled Mint and run a command suggested and this is the result
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no
2: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: yes

What exactly is Hard blocked: yes means? Can it mean that my physical switch might be faulty? It is switched on for sure..

THANKS IN ADVANCE


Does anybody have any idea??
THANK YOU IN ADVANCE.

As a test reboot and enter your BIOS setup, set to defaults and exit. After the reboot is there any difference?

I get the impression that it was working before you did the so called "upgrade" of the broadcom drivers? If so I don't know if what I am about to write will work for you. IF NOT then there is a standard work around for resolving broadcom issues -- It is as follows:

Do the following in terminal in your "/home/*user*/downloads/" directory...

sudo apt-get install b43-fwcutter
Download the a file from following link to the 'download' directory you are working in:
depending on which version of the drivers you need, download one of these files:
http://mirror2.openwrt.org/sources/broa ... .5.tar.bz2
(OR)
http://mirror2.openwrt.org/sources/broa ... .4.tar.bz2

Usually you will need the 4.178.10.4 version drivers

Depending on which drivers you have downloaded, type the following in terminal:
tar xf broadcom-wl-4.150.10.5.tar.bz2
(OR)
tar xf broadcom-wl-4.178.10.4.tar.bz2

Depending on which drivers you extracted:
cd broadcom-wl-4.150.10.5/driver
(OR)
cd broadcom-wl-4.178.10.4/linux

Then type the following in terminal
sudo b43-fwcutter -w /lib/firmware wl_apsta.o
modprobe b43


I edited as administrator the "/etc/modules" file and found that the "b43" module was in fact spelled in Upper Case letters ("B43), so I put the letter "B" in lower case and saved, it loads everytime.

@mister_lister, I would disagree that the actions you propose are a standard workaround on ubuntu based distros. I also don't believe this is simply a Broadcom driver issue as the device is initialised, hardblocked issues are often down to wmi.

I am not here to argue with you, but what I posted solved all of my Broadcom issues back when.

If your situation is truely a hard block and not simply an incorrect driver, bios issue, or physical switch issue, then you might want to try my solution.

In this case the hardblock was only reported by the Broadcom driver, the ideapad_wireless was not blocked so no wmi issue, rather a Broadcom driver problem indeed.
By the way, for Ideapad the driver is not called -wmi but ideapad-laptop. And it hardly causes any problems (as opposed to acer-wmi which was a frequent source of problems on Mint 12).

That's quite possible Albert, not quite sure of the cause, was wondering a little why there were 2 wireless adapters showing and wondering whether the ideapad one was the cause of the blocking on the broadcom when there is only 1 physical adapter afaics.

That's nothing special. Most modern laptops also have some kind of BIOS interface for reading the wifi & bluetooth switch, that's the ideapad thing in rfkill. So you're seeing it twice. Both "hard block" statuses should be the same since it is the same switch. In this case the Broadcom driver was reporting something different, while ideapad-laptop correctly reported that it wasn't blocked.
