Bug Description

My Laptop Compaq nx6325 equipped with built-in wlan adapter Broadcom bcm4311 cannot even switch on the wireless adapter in order to connect. I have found a work-around as described here: http://ubuntuforums.org/showthread.php?t=1745437 but that is not a proper solution for somebody with little experience in computers therefore I think you should look into it and correct your code in future releases as NONE of them no matter how many I have tried don't even switch on my wifi adapter without using the work-around described in the link above and also presented just below. This bug applies to ALL UBUNTU Releases not only my current one : 15.04

"I fixed my problem with the Broadcom bcm4311 drivers on 11.04 (Natty Narwhal)

Steps I took for fixing this problem: (I stole this method from http://ubuntuforums.org/showthread.php?t=1700897[user:nm_geo; post #5])

-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, [terminal]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)


hopefully this works for you all! "
