Broadcom Wireless Driver does not work

[Raz0r]

Hi guys,

my wlan driver isn't working

Output on lspci

03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

Output on iwconfig

lo no wireless extensions.

eth0 no wireless extensions.

Then i tried to figure out how to fix this and found that tutorial
http://wiki.debian.org/wl

Now i have this in my additional drivers



But my wlan still won't work so what I am doing wrong?

[TBABill]

Did you restart? If not, open a terminal and

Code: Select all

sudo modprobe wl

Wait a few then try again to connect.

[Raz0r]

I did it already.

[Clawinus]

I found the solution in another thread. You find it by searching the Newbie for the words: precious & sudo.
Good luck!

[Raz0r]

Didn't work for me. Still no solution. Btw my wireless does not even show up in network.

[AlbertP]

Please uninstall the STA driver again.

Then please run this from terminal:

Code: Select all

gksudo gedit /etc/modprobe.d/blacklist.conf

Please add this on a blank line:

Code: Select all

blacklist b43

Then please save and reboot.

[Raz0r]

So now I have to install the driver again?

[AlbertP]

No. Please don't install that driver again; by blacklisting b43 you should have out-of-the-box wifi without needing to install the STA again.

[TBABill]

OP, can you post the output of "lsmod" in a terminal? That's LSMOD in lowercase and it lists your active drivers. Curious if you possibly have bcma active and wl at the same time causing a conflict. I've seen others with a BCM4313 with an issue like that so you may need to also blacklist bcma in addition to the b43 AlbertP suggested above. Process is the same. Only do so if you see bcma and wl active in your lsmod output.

[Raz0r]

Nothing changed with the blacklist. I tried installing it again but still no solution.

Here is the output of lsmod

To be honest I don't know anything about networking on Linux I never had an issue using a wireless card till now.
So both are in so I'm gonna blacklist that bcma

Edit: bcma is still there huh?

This might be helpful either

rfkill list
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no
2: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no

[TBABill]

A couple things to try. First, open a terminal and

Code: Select all

sudo rfkill unblock all

That may allow you to use the wireless. I also see you have both bcma and wl active. If the first attempt does not help, then try to remove bcma from being active without modifying the system. Just

Code: Select all

sudo modprobe -r bcma wl

Then

Code: Select all

sudo modprobe wl

Wait a few moments and see if you can connect. If that works and you can connect, then you need to make it permanent. To blacklist the bcma, just

Code: Select all

gksudo gedit /etc/modprobe.d/blacklist.conf

Add "bcma" without quotes to the end of the list, save and restart.

[Raz0r]

The Problem is still the same bcma still shows up in lsmod even if in blacklist.conf.
Edit: After using sudo modprobe wl I can see my wireless but I am not able to activate it via the slider it simply resets. After rebooting it also disappears again.

iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

eth1 IEEE 802.11 Access Point: Not-Associated
Link Quality:5 Signal level:0 Noise level:0
Rx invalid nwid:0 invalid crypt:0 invalid misc:0

rfkill list
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no
2: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no
3: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: no

And this might be the reason why it doesn't work.

iwlist scan
lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

eth1 Interface doesn't support scanning.

[AlbertP]

Please purge the wl / STA driver. It didn't work for you. Then please remove the file /etc/modprobe.d/blacklist-bcm43.conf and blacklist b43. Then you should have brcmsmac loaded (in lsmod). If not, please try sudo modprobe brcmsmac. You also need bcma that way so please don't blacklist it.

[Raz0r]

K finished that. I found out that using iwlist scan as root gives me that

eth1 Failed to read scan data : Invalid argument

[AlbertP]

@Raz0r: if you get eth1 in your iwlist instead of wlan0, you're still using the STA (aka wl) driver. Please purge that driver (apt purge bcmwl-kernel-source) as I told you in my last post.

[Raz0r]

Exactly that what i typed in. Still eth1.

[AlbertP]

Please run this in terminal and post the output:

Code: Select all

lshw -C network

Note that it'll take some time before the output appears.

[Raz0r]

So first of all iwlist scan now shows my network on eth1 after using (slider still keeps resetting / closing connection):

sudo modprobe -r bcma wl
sudo modprobe wl

This is the output;

lshw -C network

[AlbertP]

It says driver=wl0 at the wireless. You still have some kind of Broadcom STA ("wl") driver installed. Perhaps you manually compiled it?
