Airport Extreme and Cox Internet IPv6 Problem

No encouraging, I did the same as you using the Cox DNS and iPv6 servers and am right now just at about 20 hours, and still running but expecting the dreaded reboot coming, at which time i will revert to Link Local.

Another thing I noticed was that after reseting and running test iPv6 it passed with 10/10, running it after reading your post it fails 0/10, not sure what that is about

I posted yesterday about my Cox Modem not working with my Apple airport Extreme. Last night I went to COX and got an ARRIS SB6183 (Can't remember the last number) and replaced the older ARRIS SB6141 modem. Connection to COX from it with a LAN cable to a Windoze machine worked fine.

Next I set my APPLE Airport Extreme aside and got out the older Airport (Flat white square version about 8 in square and 2 in tall). That worked fine with the new modem with the IPV6 set to Local Only as others have noted. So far everything was working when I went to bed last night so I'll check it later today and see if it is still working.

I did notice that the two DNS IP addresses had to be replaced often as they seem to disappear. So make a note that every time you edit or check the Apple router settings, to make sure you have DNS addresses loaded.

I hope that at some time in the future I can use my Dual band Airport Extreme with the COX system.

I too got an Apple number to call and after an hour of holding, it hung up on me.

So much for customer service.

FYI, I am successfully using my own Arris WBM760 modem with my six-month-old dual band Airport Extreme (actually a Time Capsule). As I have reported above, it is totally reliable with the default Cox DNS and Apple 1pv6 auto settings.

Surprised about your Apple customer service experience. Who gave you the number you used to call Apple? Whatever flaws Apple may have, their customer service is generally recognized as the best in the business, and I have always found it to be so. In 20 years, never had to give up on a call. Perhaps not perfect, but light years better than Cox technical assist.

If you go to the Support part of the Apple website you will find several ways to immediately contact them by chat or phone. You can arrange for them to call you in two minutes, and I just did that a few weeks ago for another issue. Worked great, as usual. Suggest you try the website method I mention above, and see if you have better luck.

Hope you can get to the bottom of this without more bad experiences.

I remain on local link only and have not lost internet connectivity or speed since doing this weeks ago.

If you try the Cox normal ipv6 settings, it would be only after a few days of no connectivity disconnection that you could say that it works.

Well, it took almost exactly 18 hours for the Cox IPv6 defaults to fail, which they did at 1210 PT. So, now I'm back on <blank> DNS and "link local" (i.e. IPv4 only). Hoping this setting works with this new firmware update (7.6.7 on mid-2011 Time Capsule). Link Local did not work with the previous firmware version without the once or twice-a-day disconnect. Fingers crossed!

Unfortunately, even with the update and settings to link-local I can verify Im still losing or dropping connections randomly. I can measure it when using my VPN, if the system is hard wired into the modem it works no problem and doesn't drop for a day. but if it is through the AirPort Wifi or wired it will drop intermittently.

When I got home yesterday, my internet connection was down but i was still able to connect to wi-fi. Same issue as before even with the newest update. I just reset my router and it worked again but this morning it was down again. I changed all my settings back to "local link only" now. hopefully a fix will come soon.

I installed the Airport extreme firmware update this morning (5/27), reconfigured the Airport Extreme back to IPV6 instead of local link. I then ran an IPV6 test with our Cox service. This was the first time I saw anything for IPV6 (19 out of 20 in this test vice 4 out of 20 in the past). It seems to work, sees IPV6, accepted a speed test, and works for now. We'll see if the knock off the internet issue still exists over the next few days.

Right now I m at 60 hours with utilizing Cox DNS, iPv6 automatically, and have not had any dropouts

Thanks

Unfortunately, the <blank> DNS and "link local" (i.e. IPv4 only) settings failed 21 hours after previous reset. I think I've now run thru every combination of IPv6 and IPv4 settings on this mid-2011 model TimeCapsule, and none of them will keep the link up for more than a day. I could reboot daily, but since I telework and use VOIP for teleconferences as well as am VPN'd into work all day, it is more than an annoyance when the connection drops. Cox has already done what they can, and Apple's latest firmware release doesn't seem to address this issue. Time to move on and simply replace the Apple router with something else. It's been a good run until now. Good luck to all with this.

I seem to have somewhat better success than you, I am using a mid 2013 TC, which I believe is the 5th generation,

May we get a screen shot of your settings? Mine are as below, everything filled in including the DNS servers is filled in automatically, nothing is left blank except of course the IPv6 servers, and then no domain name, and no IPv6 address.

I have had them set as below for weeks now no loss of connectivity and no slow internet speeds. My iMac is connected to the Time Capsule with an ethernet cable and I am supposed to get 150/10 and I get pretty much around 165/12 every time I have tested never below. No issues at all. My Time Capsules and Airport Extremes are all the latest version.

Always green lights, and these three Airport Extremes are pretty far from each other.

P.S. Given that Apple OSX default screen shot and Grab are TIFF images, why doesn't this Apple website allow direct upload of TIFF images for forum posts? Why do we have to convert to JPG first?

Mine's the same as yours. DNS settings are left blank by me, but then filled in "light grey" from Cox. There's no IPv6 DNS because link-local is IPv4 only.

I dunno if this is different or matters, but the DNS Servers: I have are not grey, all black.
