Unable to get wifi working in my dell inspiron 1440

I am a newbie in linux and have installed opensuse 12.1 and the installation went successfully. No I am having difficulty in getting my wifi work.
I’ve installed the driver of broadcom adapter.

This is driving me crazy…:frowning: Someone please help me…:frowning:

Did you do

sudo /usr/sbin/install_bcm43xx_firmware

You need an active wired connection
If you don’t have a wired connection, let me know.

The above command has caused a system crash (it’s a known bug) but nothing to worry about. Just wait a minute and force a reboot.

linux-shwo:~ # uname -r

Is 12.2 not 12.1

Apart from the fact that caf4926 is already trying to help you (yes, there are some nice people here), please next time try to improve on your thread by:
. using the most appropriate forum for your problem, Wireless looks as the best one to me. And in the first few “sticky” threads there you will find a lot of help already and also what technical information you are required to post to make you helpers helping more efficient.
. using CODE tags around your computer texts to make them better readable and to let them stand out amongst the story telling of a post. Use the # button in the toolbar above the post editor.


Hi, thanks for your help. I’ve run the following command and rebooted the system

sudo /usr/sbin/install_bcm43xx_firmware

Still wifi is not working… Do I need to activate something ? The network settings are now controlled by “Networkmanager” and my wired connection is working fine. But when I try to turn on wifi using the wifi switch in keyboard, only bluetooh gets activated.

Please try the following:

sudo /sbin/modprobe -rv b43

sudo /sbin/modprobe -v b43

If it still doesn’t work, post result of

rpm -qa | grep broadcom

And now also
Please install rfkill, like this

zypper in rfkill

Then post result of

/usr/sbin/rfkill list


fixed the issue… cheers…!!!:):):slight_smile:

Welcome :smiley:
