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. ;)"

Debian has packaged 2013.11.27:

Any chance we could get this into Trusty? Without it, there are weird connection issues with 802.11ac.

Come on now - surely this is embarassing?

The regdb on Ubuntu is now almost *2 years* out of date.

As of now, the latest stable version is 2014-10-07.

For all those suffering from this (and VHT issues, etc.), I've found the Debian testing package to apply cleanly and enable VHT successfully - https://packages.debian.org/jessie/wireless-regdb

Lovely, successfully fixes my laptop.

I've uploaded to wily

I've uploaded to vivid-proposed awaiting approval from ~ubuntu-sru

TEST CASE:
Buy a Thinkpad 450s in the US with "Intel Corporation Wireless 7265 (rev 59)"
If you can use the internet for 10 minutes without pulling out your hair it has worked

This bug was fixed in the package wireless-regdb - 2014.11.18-1ubuntu1

---------------
wireless-regdb (2014.11.18-1ubuntu1) wily; urgency=medium

  * Resynchronise with Debian. LP: #1284093
    Remaining changes:
    - Replace REGDB_AUTHOR with the ubuntu-devel-discuss@ list, to create
      our own private key for signing the regulatory data.
    - Explicitly override dh_auto_build to make a new private key.
    - Don't remove pubkeys, to make sure the key can be verified; but still
      remove /lib/crda/pubkeys/linville.key.pub.pem since that conflicts
      with crda.
    - debian/patches/dont_auto_create_keypair: Drop the tilde from the key
      path, since it isn't guaranteed to work on buildds.

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
