Dell Inspiron 1545 wireless driver not working in Ubuntu 12.10 64-bit

wireless drivers dell broadcom

Your device, 14e4:4315 uses the Broadcom STA driver. Please get a temporary wired ethernet connection and do:

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

Assuming the wireless switch is on, your wireless should now be working; check:

rfkill list all

I have used Mythbuntu, Ubuntu 12.10 32-bit OS, and they have all worked properly with the wifi driver which is apparently the Broadcom 4312. Then I deleted the Linux partitions, rebooted with Ubuntu 12.10 64-bit because that was the only 64-bit version I could find. I did it through USB boot, installed alongside my Windows 7.

I noticed before installing that it couldn't detect wifi connections so I used ethernet. It installed as quickly as the 32-bit version of 12.10. I finally got to the desktop environment after rebooting, and I noticed that I still couldn't connect to my wireless internet. I've browsed for hours and hours to get it working, but I still have found no answer. I hope someone can help give me a working yet simple solution. If not then I guess lay it down on me the hard way.

  What is the exact identity of your Broadcom? Run this terminal command and pick out the Broadcom wireless. Edit your question to add all the details: lspci -nn

  I still don't see the numbers. Did you add the -nn flag to the terminal command? lspci -nn I just hate to guess and give you a frustrating and wrong solution.

'kernel source missing' indicates that linux-headers was not installed or installed incorrectly. Please try again: sudo apt-get install linux-headers-generic and then do sudo apt-get install linux-headers-$(uname -r) and then try again: sudo apt-get install --reinstall bcmwl-kernel-source ; sudo modprobe wl

It looks like you typed bcmwl kernel-source; it is actually bcmwl-kernel-source.

chili555 about 11 years

Run each command one at a time and post the result: sudo apt-get install linux-headers-generic. How does this go?

We really ought to update before we continue: sudo apt-get update && sudo apt-get -y upgrade. Please post any errors or warnings. The whole output is unnecessary unless there is something alarming.

Please restart all running instances of firefox, or you will experience problems.
chili555 about 11 years

I think we're OK so far. Now the next one: sudo apt-get install linux-headers-$(uname -r) Result, please? It may, I hope, say it's already installed.

I assume you said Y. If not, please do so and then please go on to the next one: sudo apt-get install --reinstall bcmwl-kernel-source We're close, Warren!

So now is your wireless working after you detach the ethernet?
warren about 11 years

ahhhh :"D ITS ALIVE!!!!! thanks,you're the best,do i require rebooting? ,oh and before i got rid of 32 bit version,i got rid of it because it was only a read only file system,would i worry about this in 64 bit?
chili555 about 11 years

I would do nothing but enjoy your wireless. Update Manager will probably want to install whatever was skipped above. Please accept my answer above and have fun! I doubt you will have any read-only issues but post a question here if so.
