The only thing thus far that has worked is your solution listed above: Posted on Mar 2, Mar 26, 4: Someone else on the Apple Support forum commented on contacting Apple regarding this issue. This made sense to me. If the problem is with Cox's implementation of IPv6, switching servers could solve the issue. The DNS settings in your router basically tell the router which servers to connect you to. I have made these changes and have been using them for the last 36 hours without issue. As opposed to the previous temporary fix switching IPv6 on the Airport to link only local , I view this as a more permanent fix.
The previous temporary fix would leave you without any IPv6 support at all. Some also reported internet speed issues after this fix. I found my speeds okay during the day, but questionable during peek hours at night.
So, the new fix will restore IPv6 functionality, reroute your internet connection through Googles servers and should restore or improve speed over the previous fix I tested speeds a lot over the last 24 hours-some speed drop at night during peek hours-but that's really to be expected and it's not as bad as it was before-on a Mbps connection, I was still getting On to the fix, then. This was done using Airport Utility for iOS. Should be similar on Mac. Open Airport Utility app. Tap on your Airport basestation's icon. Tap "Edit" in the upper right hand corner of the screen.
Tap "Internet Connection". DHCP should be highlighted in blue at the top of the screen. Under "DNS Server" you will see a primary and secondary set of numbers.

These are the Cox DNS server numbers. Write these down. You'll need them should you ever decide to revert back. If you did not make this change, Cox's DNS server numbers should be displayed here. Again, Write these down, so you may revert later. I haven't tested this, but, in theory, if you don't write these numbers down, you should be able to get them back by resetting the Airport to factory defaults with the hard reset button on the back of the unit. Now the changes. If you are using Google, you'll enter the following. There are other public DNS servers you can use like Level 3 and others.
Do an internet search for it. For Google: Type in "8. In the "Secondary" field, type "8. Now go to the "Secondary" field and type " This switches you to Google servers after the unit reboots. Tap "Done" in the upper right hand corner of the screen. If you had previously turned IPv6 off via "link only local"' we will need to fix that to restore IPv6 functionality via Google servers.
If you did not make this change, tap "Done" at every screen you see and the unit will reboot and your changes will take effect. If you did make the link only local change, tap "Advanced", "IPv6", "Configure IPv6" and change this from "link-only local" to "Automatically". Keep tapping "Done" at every screen to save your changes and reboot.
Once rebooted, you should be able to go back to the screen where the DNS settings are and see that they are now pointing to Googles servers. At this point, power off both the cable modem and AirPort for about two minutes. Power the modem back on first and let it boot. This could take a minute or two. Then power up the AirPort. Once everything is back up and running, go back into AirPort Utility.

We are going to check that you have a functioning IPv6 connection. Tap on your AirPorts icon. Tap "Advanced" then "IPv6". Now open up Safari and go to www. This site will test the state of your connections' IPv6 readiness. You should now have a working IPv6 connection. I would ask that some of you try this out and report back to the group as to whether it is working for you. For some, these changes may seem a bit intimidating. But, there's nothing here that can't be undone with a hard reset of the AirPort the tiny button on the back that you have to press in with a paper clip for 10 seconds.
This would completely reset the AirPort to factory defaults like it was when you first unboxed it when it was new. Best of luck everyone. Hope this helps. Page content loaded. Mar 2, Mar 3, 7: Thanks so much for this. This problem of wifi connection dropping has been driving us NUTS for months, with several calls and service calls from Cox plus two new modems, one of theirs and finally one of our own.
It was getting so that we would have to unplug and replug in the modem every 2 hours. Changed the settings for ipv6 and everything seems to be working right now. Fingers crossed.
Step 1: Open Airport Utility
I am happy to help - but you mentioned something I noticed by accident but didnt mention. At one point when the hardwired router connections failed, I noticed with Wifi on my Macbook was still working. So it seems that whatever goes wrong - it is not always all the connections - This may be a clue to Apple as to what may be going on.
Mar 5, 7: I was able to get it to keep the connection with "Link-Local Only" option but it has killed my speed. We used to see mbps DL now it ranges anywhere from mbps but mostly sub 30mbps. Its pretty frustrating when you buy good hardware, pay good money for decent speeds, and arent even coming close to what you should be seeing.
Seem like Apple is playing the blame game. Mar 6, 3: Have seen it both wired to the AirPort as well as on wifi. Wifi will show good, solid signal to the AirPort but Safari will not load a webpage. Started happening a week ago, which coincides with Cox's roll out of IPV6 in my area. Happens every night between midnight and 2am, but also happens sporadically throughout the day.
Rebooting the cable modem usually does the trick and gets it working again, but sometimes need to reboot the AirPort, as well. Initially thought the problem was with the AirPort. Called Apple and they said because it was under warranty, to bring it to the Apple Store. I did and they gave me a new one. Same problems as before. Called Cox and they sent a tech to the house. Checked everything from the modem back to the pole. No problems found. Tech replaced the modem and left. Same problems popped up again that night.
