We got it to work now. We had to set "Unknown Address Multicast NS
Forwarding" to disabled. When this setting is enabled on AireOS 7.6,
IPv6 on OSX does not work, at least not in our environment. Something
appears to go wrong with DAD on Apple's operating systems when it is
enabled. We noticed that Global addresses where marked as duplicate in
ifconfig. And sometimes we would not get global addresses at all. In
these situations the interface came up with "nd6
options=9<PERFORMNUD,IFDISABLED>".

We use SLAAC. We had issues with 7.6.100.0 too, that is why we tried the

We only see this problem with OSX 10.9.x and only on wlc 7.6.*. IPv6 on
Linux, Windows and Android works fine on wlc 7.6 as far as we can tell.
On wlc 7.6, for some strange reason, the Mac chooses its link local
address as source address when connecting to GUA addresses. This
behaviour only happens on the wlc 7.6.*. ping to the default gateway's
link local address works. ifconfig, routing table and neighbor cache
looks correct. It updates the lifetime counters on GUAs when new RAs
arrive. Move the AP to a 7.4 controller, and the Mac starts using its
GUA as source address and it works.

No issues here with 7.6.100.0 on WiSM2s and SLAAC.
Was it working with 7.6.100.0 for you and broke when you went 7.6.100.7?
Are you using SLAAC or DHCPv6?

Anyone having IPv6 working on Mavericks with 7.6.101.7 on the WLC?
IPv4 appears to work now, but we are still having problems with IPv6
on both OS X 10.9.1 and 10.9.2 when they connect to wlc 7.6. Works
fine on wlc 7.4.

The issue has been tested in 7.6.101.7, and appears to be
resolved.

Looks like MacOS 10.9.2 became available today from the
App Store.
It will be interesting to see if the wifi roaming and
dropping issues
have been resolved.
