I have an Acer V5-171 laptop, with a BCM43228 802.11a/b/g/n wireless network adaptor. In Ubuntu 12.04 and 12.10, I had absolutely no issues with my wireless connectivity. I upgraded to Ubuntu 13.04, and the wifi device dropped out.
I fixed the wifi by performing the following command (found via this forum post):
sudo apt-get install --reinstall bcmwl-kernel-source
I’d had a few issues with my Ubuntu install – mostly due to tinkering, so I thought I’d give a few other distributions a shot. Unfortunately, the state of the support of this driver was even worse on the others I installed.
Sabayon 13.04 (note, this is from memory!): You need to edit /etc/modprobe.d/blacklist.conf and uncomment the blacklisting of the b43 module. You need to comment the blacklisting of the 5 or so modules above it (mostly to enable the “wl” module). While this brought the NIC up, it didn’t survive an upgrade of packages, and by this point I’d spent about 2 days on it, so I was getting ratty, and wanted to try something else.
Fedora 18: Also didn’t work – I checked this distro because of my issues with Sabayon, but I figured that as it wasn’t working, perhaps there was something fundamental going on – probably either installing a package, or blacklisting a module would have solved this – I won’t know now!
OpenSUSE 12.3: I finally settled on installing OpenSUSE after I’d realised my issues were just with the module and not the distribution. I’d considered running OpenSUSE for some time and thought I’d give it a shot. I found a post (which I’ve subsequently lost) which showed that the package wasn’t installed by default to support this adaptor, so I found this page which listed both the relevant kernel module (in my case the x86_64 12.3 package) and the matching software package. As I was doing the install semi-offline (I can’t tether my phone to the laptop right now, and had no wired access) I transferred the relevant RPMs over, and installed them using rpm (the RedHat/Fedora/OpenSUSE/etc package manager). Wireless came up, but I’m missing certain APs – probably a configuration item that I’ve not yet fixed. It’s not disastrous, but is annoying :)
