Hello,
I could have my wireless connection on Acer Aspire V3-471G with the card BCM43228 all in good order after upgrading from Trusty Thar to kernel Wily 4.0.4 by installing the package bcmwl - 6.30.223.248+bdcom-0ubuntu3.

To achieve this, I downloaded http://launchpadlibrarian.net/206246268
/bcmwl-kernel-source_6.30.223.248%2Bbdcom-0ubuntu3_amd64.deb and used
the command dpkg in the Terminal to build the module on my machine.

Thank you !

Title:
  Bcmwl-kernel-source doesn't compile against 4.0

Status in bcmwl package in Ubuntu:
  Confirmed

Bug description:
  With a 4.0 kernel provided by http://kernel.ubuntu.com/~kernel-
  ppa/mainline/v4.0-vivid/ , bcmwl-kernel-source fails to compile.
  /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/make.log is attached, key
  problems excerpted below:

  /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c: In function ‘wl_cfg80211_get_station’:
  /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:1444:20: error: ‘STATION_INFO_TX_BITRATE’ undeclared (first use in this function)
     sinfo->filled |= STATION_INFO_TX_BITRATE;

  /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:1444:20: note: each undeclared identifier is reported only once for each function it appears in
  /var/lib/dkms/bcmwl/6.30.223.248+bdcom/build/src/wl/sys/wl_cfg80211_hybrid.c:1457:20: error: ‘STATION_INFO_SIGNAL’ undeclared (first use in this function)
     sinfo->filled |= STATION_INFO_SIGNAL;

  
  The need to run a 4.0 kernel is because the 3.19.0 kernel in Vivid will corrupt and fail on a btrfs system. Either 3.19.5 or 4.0 are required to avoid this corruption: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1445252
