Public bug reported: 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. ;)" ** Affects: wireless-regdb (Ubuntu) Importance: Undecided Status: New ** Tags: 802.11ac regdb vht -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1284093 Title: Please update regulations to support VHT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wireless-regdb/+bug/1284093/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
