Broadcom BCM4312 card not working on Dell Vostro 1520 runninmg Jaunty

[Mark2322]

This is how I got wireless driver to work on a dell inspiron600m laptop. Keep in mind I am a noobie but this may help a little. I am using the broadcom 4311 drivers so hope this helps. This was on a fresh install too. Okay, after some tinkering around I was able to get them to work. I will try to recite the procedure to the best of my knowledge as I didn't write it down. I first used an ethernet connection and opened the terminal and entered sudo apt-get install ndisgtk. I entered my password for the sudo command and it automatically installed ndiswrapper-utils-1.9. Then I had to blacklist native drivers by entering the following commands in the terminal:
echo -e "blacklist bcm43xx\nblacklist b43\nblacklist b43legacy\nblacklist ssb"
then entered:
sudo tee -a /etc/modprobe.d/blacklist
Okay then without closing the terminal, I opened another and entered:
sudo ndiswrapper -i ~/drivers/drivername.inf
Now I had already downloaded the drivers for my wireless card and opened
the .exe file in archive manager and extracted the .sys files and the only.inf file
to a folder on the desktop which I named drivers
So in my case I entered sudo ndiswrapper -i ~/drivers/bcmwl5.inf
then went to windows wireless drivers in system/administration/windows wireless drivers
and chose to install new driver. I pointed it to the .inf file in the folder I named drivers
and installed. It gave me an error message saying that hardware was not present but the windows
wireless drivers window said hardware was present so I rebooted and was able to connect to my gateway
I hope this helps because I know I am not the only on with this problem. However I am using a dell
inspiron so it may not work for everyone but it should point you in the right direction if you are having trouble

bit@tau:~$ lsmod|grep -e b43 -e ssb -e wl -e ndis

This is showing ndiswrapper and wl running at the same time. Which one are you trying to use? If you are using ndiswrapper, try the following:

sudo modprobe -r b44 ssb ndiswrapper wl
sudo modprobe ndiswrapper
sudo modprobe b44
sudo iwlist scan

If you are trying to use the Broadcom STA (wl) module, try the following:

modprobe -r b44 ssb ndiswrapper wl
sudo modprobe wl
sudo iwlist scan

organadino and cadcamjim-
If you are using the Broadcom STA option, can you check and see if the following command produces a wl.ko file:

ls /lib/modules/2.6.28-13-generic/volatile/wl.ko

If it does not, please try the following:

sudo /etc/init.d/linux-restricted-modules-common start
sudo depmod -a
sudo modprobe wl
sudo iwlist scan

Still no wireless. the ndiswrapper one stopped eth1 from working and using wl produced

However, when I try to connect using wicd it never gets past "obtaining IP address"

I upgraded my Ubuntu 9.04 box today with the latest updates, and now my wireless won't work (A Broadcom BCM4312). I think it might have to do with an updated kernel.

If in the past you've had success with wifi on Jaunty with BCM4312, and find that it recently has stopped working, you may wish to check my comments in this topic:

http://ubuntuforums.org/showthread.php?t=1189752

BTW, I'm running kernel 2.6.28-13. Once I backed-out the recent hal-related updates (0.5.12~rc+git20090403-0ubuntu3), my BCM4312 began working automagically again. YMMV.

You are quite welcome, I'm happy to have been of help !

I ended up with a different solution. It would appear that something went awry during the install of a package or something. I ran:

sudo /sbin/lrm-manager
sudo modprobe wl

The FATAL message I was getting, was apparently an indicator that that command had not been run successfully after the install (or so I guess, since I don't understand what that command does ).

This worked for me. Wireless has been sketchy for the last couple days but an ubuntu-mobile update (kernel modules) killed it today. This fixed it. THANKS!!!

I downgraded the HAL libraries (from xxxUbuntu3 to xxxUbuntu1 and block the version in synaptic) but when ubuntu loads whit kernel XXX-13 still the wifi adapter do not work.. but when I boot whit kernel XXX-11 its detected and works properly with kernel XXX-11.

This what I get with kernel XXX-11:

oscar@oscar-laptop:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

eth1 IEEE 802.11 Nickname:""

this is what I get with kernel XXX-13:
