Wireless Not Enabled

Postby katyauser on Wed Aug 17, 2011 9:04 am

Hey, I just installed the latest version of Linux Mint (Linux Mint Main Edition 11 RC 64bit - DVD Install) on my Dell Inspiron 1545 laptop and while everything else is up and running good I'm having an issue with the wireless card. I installed the required drivers but the option "Enable Wireless" in the network connections is greyed out.

I tried "lspci -vvnn" in the terminal and got this back:
Code: Select all
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
   Subsystem: Dell Wireless 1397 WLAN Mini-Card [1028:000c]
   Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
   Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
   Latency: 0, Cache Line Size: 64 bytes
   Interrupt: pin A routed to IRQ 17
   Region 0: Memory at f69fc000 (64-bit, non-prefetchable) [size=16K]
   Capabilities: <access denied>
   Kernel driver in use: wl
   Kernel modules: wl, ssb

Anyone got any idea what could be wrong ?

Let's see what driver you installed. Please open a terminal and run and post:
Code: Select all
sudo modprobe wl
dmesg | grep -e wl -e b43
If there are errors or warnings, the result will be informative. Please post the terminal output here. Thanks.

Copied and pasted the above into the terminal and got this back:
Code: Select all
[   21.184260] wl: module license 'MIXED/Proprietary' taints kernel.
[   21.257032] wl 0000:0c:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

I believe wl is correct for your device and, according to the timestamp in dmesg, it loaded during the normal boot process. Let's check something else:
Code: Select all
rfkill list all
sudo rmmod -f dell-laptop
sudo rfkill unblock all
rfkill list all
Thanks.

Tried the above in the terminal and got this back:
Code: Select all
~ $ rfkill list all
0: brcmwl-0: Wireless LAN
   Soft blocked: no
   Hard blocked: yes
1: dell-wifi: Wireless LAN
   Soft blocked: no
   Hard blocked: no
~ $ sudo rfkill unblock all
~ $ sudo rmmod -f dell-laptop
ERROR: Removing 'dell_laptop': No such file or directory
 $ rfkill list all
0: brcmwl-0: Wireless LAN
   Soft blocked: no
   Hard blocked: no


After I tried the above, the wireless is now working. Thank you for your help. :)

Is there any chance you'd like to make it permanent?? It looks to me like all it took was:
Code: Select all
sudo rfkill unblock all
Would you please reboot and issue that single command? If that's it, we'll tweak one file to make it persistent. If not, we'll dig deeper.

I rebooted and the wireless works -- didn't even have to enter the "sudo rfkill unblock all" command in the terminal.

This is the first step that I see in the instructions
I. scanning WIFI PCI devices...

I`ve made the step told :
gabriel@altius ~ $ sudo modprobe wl
gabriel@altius ~ $ dmesg | grep -e wl -e b43
[ 23.263698] wl: module license 'MIXED/Proprietary' taints kernel.
[ 23.378371] wl 0000:06:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19
[ 23.378384] wl 0000:06:00.0: setting latency timer to 64
gabriel@altius ~ $ rfkill list all
gabriel@altius ~ $ sudo rmmod -f dell-laptop
ERROR: Removing 'dell_laptop': No such file or directory
gabriel@altius ~ $ sudo rfkill unblock all
gabriel@altius ~ $ rfkill list all

But as you see when I got to the second step I`ve obtained this message.

I wonder if you can help me. My linux version is linuxmint11

I don't believe wl is correct for your device. https://help.ubuntu.com/community/WifiD ... atty_11.04

Especially see:
CAUTION: This pci.id is also claimed by the Broadcom STA driver provided by bcmwl-kernel-source. Installation blacklists b43 and ssb. The driver bcmwl-kernel-source driver wl doesn't work well and b43 and ssb are preferred. To remove the incorrect driver and blacklist, do:

Code: Select all
sudo apt-get remove –purge bcmwl-kernel-source
sudo rm /etc/modprobe.d/blacklist-bcm43.conf
Post back if you need additional guidance.

Thank you for your help.
I've made what you told me and the result was this:

gabriel@altius ~ $ sudo apt-get remove –purge bcmwl-kernel-source
[sudo] password for gabriel:
Sorry, try again.
[sudo] password for gabriel:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package –purge


So wireless still not works
I've tried also to remove the drivers with software manager but still dosen't work

The text is a bit hard to read for me on the forum. It is not -purge. It is, instead - -purge, with no spaces between the two minus signs. Please try again.

Let's see:
Code: Select all
lsmod | grep b43
dmesg | grep b43
If the first command doesn't show that the driver module b43 is loaded, please do:
Code: Select all
sudo su
echo b43 >> /etc/modules
modprobe b43
exit
Now is it working?

If he has the exact same card, then yes.
-- Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
==> PCI ID = 14e4:4311 (rev 01)
If not, post the details in a new thread and we'll get you going.

Glad it's working!
