As reported elsewhere, IPv6 tunneling seems to be broken in the 7.6.3 update.

 

After updating the Airport Extreme (4th gen) tells me that the IPv6 connection is broken and wireless clients are not assigned IPv6 addresses.  I tried several different IPv6 tunnels (tunnelbroker, etc) and none worked in 7.6.3.  Reverting to 7.6.1 immediately solved the problem.

    Well I gave it all a try. Upgraded the three 5th gens, then rolled them back and upgraded again. They seemed to work for about 15 minutes then things started to go unstable. The primary started giving errors about double NA'T and handing out DHCP and the cable modem was rebooting like crazy. When it was working the speed test app is all over the place to, never stable and some times it hangs and if it does that you have to toggle wifi on and off to get Internet to come back on that device. All three routers act the same. Tested with MacBook Air, iPad mini, IPhone 5 and Latiude e6220 with 6300 intel wifi chip. I rolled the all back for now to 7.6.1 and Cable is now stable, routers are all stable, no more hangs and weird stuff. My speeds area ll back to normal and my shared drives and wifi printer are back as well.

    The 7.6.3 update breaks IPv6 Tunneling on 1st Generation Time Capsule as well

     

    Reverted back to 7.6.1.

     

    Apple seems to break IPv6 Tunneling every other release.  Is someone not merging bug-fixes back into the main trunk of their code repository before starting on a new rev??

    Glad I'm not alone with this update.   I went back to 7.6.1 because of he ipv6 tunnel not working to he.net.  I thought apple had a good qc/qa for software deployment?

    Yep.  IPv6 has been working fine for over a year.  Now doesn't work (Tunnel Broker).  Rolling back.

    How does one roll back? Airport Utility 6 doesn't appear to have advanced settings to select firmware revisions; Airport Utility 5.6 will not install on OSX 10.8.2.

    Hover the mouse pointer over the current version listed and click on it and it should show the previous versions. Also this can be done from an iPad or IPhone with airport utility install on it. There are screen shots of all this on a different thread as well.

    Thanks, it_caveman.

     

    Found the official documentation here:

    http://support.apple.com/kb/HT1218

     

    To downgrade firmware in Airport Utility 6:

    - Click on the Airport you want to downgrade.

    - Hover your cursor over the version number

    - Press Alt/Option to turn it into a drop down menu

    - Select the version you wish to downgrade to.

    How would one know that IPv6 tunneling is needed? for their everydaty work.

     

    When should one downgrade their firmware?

     

    Thanks

    Hello all,

     

        I have an SIXXS tunnel that I initially had problems with. I discovered that I had a problem with the way my tunnel was defined. My experience is that this firmware is less forgiving on the definition of the tunnel.  In my case, I had the ipv6 prefix wrong and the old firmware due fully ignored my setting and made it work. The new firmware I had to fix it. Ipv6 tunnels can be confusing to set up. 

     

       Anyone who doesn't understand this thread, don't worry you don't need to downgrade.

    If you have the time could you enlighten us about IPv6 tunneling just the same.

    Sure.  Since it was asked, let me explain ipv6 tunnelling for you all.

     

    First, IPV6 is a completely separate and "new" network from IPV4.  You can only have an IPV6 network or only an IPV4 network or both.  IPV4 is the "original" internet.  If you ever have seen something like 192.168.122.22, that is an IPV4 (I)nternet (P)rotocol address.  This difference is important to understanding a tunnel.

     

    As the name implies, a tunnel goes through something.  In this case, a tunnel takes the IPV4 that you get from you (I)nternet (S)ervice (P)rovider and carries the new IPV6 data across to through your tunnel to an IPV6 ISP to connect to the IPV6 network.  SIXXS and Hurricane Electric are two of the free US providers that will allow you create an IPV6 tunnel so that you can get to web sites on the new network (IPV6 network). 

     

    I hope this helps.  If you have further questions, I will be hanging out and will be glad to try to answer them.

     

    John
