How to get Broadcom BCM 43XX Wireless card working
- by Fer1805
NOTE - Although this question is for a specific version of Ubuntu and a specific Broadcom model, the answer to it is for most Broadcom models and versions of Ubuntu 11.04, 11.10, 12.04 and 12.10. If you have come here from another question, feel free to read the answer instead. The answer covers many problems with several solutions.
I'm having serious problems installing the Broadcom drivers for Ubuntu 11.04. It worked perfectly on my previous version, but now, it is impossible. I'm a user with no advance knowledge in Linux, so I would need clear explanations on make, compile, etc.
I was following the instructions on the following blog, with no luck.
How can I get Broadcom BCM4311 Wireless working?
Can someone help me?
Edit:
For the command: "lspci | grep Network", I get the following message:
06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
For the command: iwconfig, i get the following:
lo no wireless extensions. eth0 no wireless extensions.
When i follow the following steps (from the above link), there are a NO error message at all:
open the 'Synaptic Package Manager' and search for bcm
uninstall the bcm-kernel-source package
make sure that the firmware-b43-installer and the b43-fwcutter packages are installed
type into terminal:
cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl'
(you may want to copy this) and see if the term blacklist bcm43xx is there
if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf
put a # in front of the line: blacklist bcm43xx
then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly).
reboot 'End of procedure'
Before (not ubuntu 11.04), if i wanted to connect wireles, i just went to the icon at the upper side of the screen, click, showed ALL the wireless network available, and done.
Now, the only options i see are:
Wired Network
Auto Eth0
Disconnect
VPN
Enable networking
Connection information
Edit connection.
hope above info is enough for your help.
