I install vivid and tried to download some packages (for an upgrade to
wily).  After initial successs download slowed and pings to google.com
were equally 1000ms. Other computers on my network for pings of 30ms.
On installing this package and rebooting the packages all downloaded
fine and pings to google.com were 30ms reliably for the 30 minutes it
took to download them.

I installed 2014.11.18-1ubuntu1~ubuntu15.04.1 from vivid-proposed

Title:
  Please update regulations to support VHT

Status in wireless-regdb package in Ubuntu:
  Fix Released
Status in wireless-regdb source package in Vivid:
  Fix Committed
Status in wireless-regdb source package in Wily:
  Fix Released

Bug description:
  Only very recent versions of wireless-regdb have support for VHT
  (80mhz channels); in addition, all current kernels have a bug that
  will cause your card to fail to associate with a VHT ap when your
  local regdb didn't allow VHT:

  https://bugzilla.kernel.org/show_bug.cgi?id=70881

  I have updated the existing Debian bug requesting this too:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=729089

  Well, more precisely I have emailed the update but it hasn't gone
  through yet.  :)

  I would recommend updating to 2013.11.27 (current upstream) as it
  includes other regulatory fixes. I would also recommend applying this
  to at least Precise and Trusty, possibly Saucy since it is still
  supported.

  Here is the update that should post to the Debian bug soon:
  "I would much appreciate this, especially you make the jump to 2013.11.27. The new regdb will also solve issues with 802.11ac; the referenced version appears to be the first with support for 80mhz channels. Without the new regdb (or a patch the kernel that masks the symptoms, below), when you connect to an AP that supports 80mhz channels, you are disconnected with a nearly useless error. Link to the ticket, with details and the symptom-masking patch that will be in future kernels:

  https://bugzilla.kernel.org/show_bug.cgi?id=70881

  It would be great if we could get the new regdb upstream into Debian
  asap; in the meantime I will try to get an updated version into a ppa
  for Ubuntu users at least. ;)"
