Airport Extreme and Cox Internet IPv6 Problem

hipsterpdx, I just noticed in your description of your setup you say,

"to extend coverage I have 3 additional AE's that are hard wired, configured to "Create New Network" in Bridge Mode."

With that configuration you are not extending your network, you are creating three additional separate networks with each AirPort router. To "extend" the network you should have those set as I show in the screenshot below.

Gino...sorry for the confusion and thanks for the reply......I should have said....to provide additional coverage throughout my house, in additional to my Main Airport Extreme Router, I have 3 additional Airport Extremes that are hard wired to ethernet (all on same network) that are ALL configured in Bridge Mode with Network Mode set to "Create a wireless network" AND with ALL four AE's configured with SAME Wireless Network Name, SAME Wireless Security and SAME Wireless Password - effectively creating a roaming network. If I did not have ethernet wired access to each AE, I would have set up to "extend wireless network...hope that makes sense...

As an aside, in Palm Desert, CA this week at my other place, running a Motorola SB6121 cm with Time Capsule (latest model) 7.7.7 (no other network devices), on TIME WARNER: with Time Warner there have been no disruptions, no issues not this week or in the past year whenever I have been here, just runs fine by itself no tweaking needed. This is a slow internet plan, advertised 20/2, and have been getting better than that at all times.

Tested today:

test-ipv6.com on my MacBook Pro here at 9/10 (Timeout on the "Test if your ISP's DNS server uses IPv6")

ipv6-test.com at 17/20

(interestingly the fallback test comes in fine on Chrome browser, but the DNS6 + IP4 and DNS6 + IP6 tests both are Unreachable.)

Same results on all devices, all browsers.

Again this is with Time Warner Roadrunner.

TheTime Capsule is set for Configure Ipv6 automatically / Native, and Block Incoming ipv6 connections / Allow incoming ipsec authentication are both CHECKed.

Whatever enhancements that were done has solved all the issues I was having, no having to reboot modem/router, no loss of speed and consistently passing all IPV6 tests

Thanks for your help and work in getting this matter resolved

I have had no problems past two weeks while running with the auto ipv6 settings with Cox.

I went ahead and upgraded my modem to the Netgear CM600. I don't notice any difference (which is okay, but I did it anyway). I am on the Premier plan 150/10 and am getting better than that via ethernet to my main iMac. WiFi speeds vary but are not bad I think given the size of the compound.

Anyway, this is my new MAC address:

Let me know after you have copied it down I will delete the image. Thanks!

Quick update from San Diego.....so far so good....changed from "local link only" to ipv6 - Cox Premier Internet, Arris SB 6190 Router, latest version Airport Extreme Router (hardware and software)...been stable since 6/17......

Yesterday around 7pm PST all internet died I had orange lights on Airport Utility for the modem, Time Capsule and two of the Airports. But by the time I got to the modem/router all was well resumed on its own so things were dead for only maybe five minutes.

I am getting a little sluggishness loading websites, such as yahoo mail, spamcop, etc. (Got stuck got the Kill or Wait prompt on Chrome browser) but speedtest.net normal and http://www.test-ipv6.com/ shows 10/10. I still can't get better than 16/20 on http://ipv6-test.com/ on the iMacs (Fallback failure) for most browsers most of the time. I was wondering if maybe this new CM600 doesn't work as well as the CM400, although that doesn't make sense. I almost want to revert back to the slower modem, since both are overkill anyway for my Premier 150/10 plan. I don't recall this intermittent sluggish loading of websites with the CM400.

I had the internet disconnectivity problem this morning about 8am PST. Only a hard reset of the modem and Time Capsule rectified the problem.

The iMacs were unable to load any websites - both the hardwired ethernet one, and the WiFi ones. All lights were green for all devices on Airport Utility, and Network / Assist Me / Diagnostics would get a "Your internet connection appears to be working correctly." When trying to load websites they would get this sort of error message on the browsers:

NOTE: that I do not use a proxy server and firewall is turned off on all my Macs.

At the same time the iOS devices like iPhone 6 plus, iPad Pro, iPad Air 2 appeared to be working fine. Speedtest app on these devices showed working connection, although slower than usual. I do believe I have a clue though this time.

When I ran http://www.test-ipv6.com/ on the iPhone 6plus, got this:

and then when I ran http://ipv6-test.com/ on the same iPhone I got this:

So even though I was getting internet on the iOS devices, there was some issue at hand. Somehow the iOS devices were able to overcome the lack of ipv6 and still give me internet, while the iMacs were not able to overcome. Seems to be that web browsers were unable to overcome this fallback issue. I tried both Chrome and Firefox on the iMacs, same result unable to load sites.

As noted, a complete restart of the CM600 modem and Time Capsule resolved the issue. Will keep you posted.

(I can't see why this faster CM600 would have this issue while the CM400 lasted all last week with no issues, but if this happens again I might revert to the CM400 modem.)

Well, was hoping this problem was a thing of the past but this morning got 0/10 and 4/20 on the IPv6 tests. Restarting my AirPort fixed it for now.

Was your connection still working when this happened, and you just happened to try the v6 test? Or was your service down and then you tried the v6 test?

I've been checking it most mornings and when I get home from work in the evening. Connection was still working, maybe a bit slow but up and running.

I noticed my Apple TV seems to now be having connectivity issues and is helped by a restart (reboot). Particularly noticeable on ABCNews channel, which seems to stall when asked to stream a news video. This seemed to start a couple of weeks ago. Coincidence?
