I see on 2014-05-13 it says: "This bug was fixed in the package bcmwl - 6.30.223.141+bdcom-0ubuntu3"
Why wasn't the updated package, from 9 months ago, included in 14.04.2's install? That would have fixed the issue easily. For anyone having this problem, rather than do code editing and compiling and everything mentioned above, you can grab the bcmwl-kernel- source package for Utopic (14.10) from here: http://packages.ubuntu.com/utopic/bcmwl-kernel-source Download the amd64 or i386 version, whichever you need, and install it (note: you will still need dkms installed on your system to install it). I just double-clicked it and let Ubuntu Software Centre do the install. That got my wireless interface on and working as expected. Can we get the updated package put into the Trusty repositories, or have the Utopic one added to the backports? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1307744 Title: bcmwl-kernel-source 6.30.223.141+bdcom-0ubuntu2: bcmwl kernel module failed to build [error: too few arguments to function ‘cfg80211_ibss_joined’] Status in bcmwl package in Ubuntu: Fix Released Bug description: installation of the kernel 3.15-RC1 on trusty...
