Losing internet connection???

Same problem with Cox and wireless router. Started dropping wireless about three weeks ago. Numerous calls to Cox were frustrating to say the least. Bought new modem, still no improvement. THEN I saw this thread. Set AE to "Link-local only" and have not had a problem for a week now. Hope it sticks.

Discussed with Cox again to let them know about the issue. I actually spoke to a female rep (Breanna) who, as soon as I said I was having problems with dropped internet, asked "Do you have an Apple router?". Bingo! So they know. It just depends who you talk to. She stated they have no idea why this is happening but Cox is "working with Apple to fix it". Yeah, right.

At any rate THANK YOU to all who helped finding a fix for this issue.

Just wanted to add my own experience because this thread solved my problem. I have Cox and a Time Capsule. It worked fine for a year, then I started getting regular disconnects. After reading this (and similar) threads I switched to Link-local Only and so far the problem has disappeared.

Thanks all.

Just found this tread, I am in Metairie, suburb of New Orleans and am also having this issue of randomly loosing internet connection through the day, with Cox although it only started a couple day ago, tried finding out from Cox if the where implementing iPv6 in my area and that was a waste of time asking that question, I just changed my setting to link-local hopefully this will help.

I've also been having issues with my Apple Airport Extreme in Gainesville, Florida. I've had it for a couple years without issues, but around the same time as the rest of you guys, my internet would drop out daily, sometimes several times a day and I would have to unplug my modem and router to fix it. I thought it was an issue with the Cisco DPC3010 that I had so I had it replaced with another one and my connection continued to drop. So I thought I would upgrade my modem to the Motorola SB6141 modem, but unfortunately the problems persisted. Then I found a ton of people saying that this was an issue with Cox and that their implementation with IPV6 is the issue. I've switched my router settings to link-only about a month ago but my connection still drops out but a lot less frequently. It lasts anywhere between 3 days to a week before it drops out again. I then just unplug the modem and the router for a few minutes and plug everything back in and my connection is back. I really do not want to have to buy Cox's gateway because I spent enough money on this router and don't feel like spending more money. Hopefully Cox and Apple are really working together to solve this issue but I have a feeling it will be awhile before this issue is solved

It's been 4 days since I changed my link local settings and so far no drops out yet, I say yet because soon as I post this it will drop out, I am using a Cisco DPQ3212 modem/gateway supplied by Cox that does not have a built in router, but I do have telephone service

Same issue here. Just changed to link local only and seems to work.

Same issue here. I have an Airport Extreme (6th gen) and Motorola SB6141. These two devices were working flawlessly with each other for at least 2 years until just a few days ago. Actually I'd started seeing very intermittent issues since late last year, but for the last week the issues started to get worse until I was seeing at least one drop a day for the last few days. Until now my connection had been very stable and was always able to correct itself even in those rare cases where it would drop out.

Did some troubleshooting and discovered that the wifi network and local network were just fine, as was the connection between the cable modem and Cox. I noticed that when the connection would "disconnect" it wasn't really disconnected, rather the issue is that DNS lookups would no longer resolve through the router, even if specific IP addresses were still pingable. A reboot of the Airport would resolve the issue (until the next time a few hours later).

Found all of these threads, took a quick look and noticed that Cox has enabled IPv6 in my area at some recent point in time based on a few online IPv6 testing tools, and the fact that I had IPv6 addresses assigned by DHCP.

I've switched my IPv6 setting from Automatically to Link-Local Only as recommended here. I can confirm that this did disable IPv6 externally. I guess now I'll just have to wait and see whether this resolves it.

I have been using Link Local only for weeks and it has been slower than before the IPv6 upgrade but at least my connection doesn't go out. However last week, it went down again. Since I complained to BBB and registered complaints with several state and county agencies, I now have the direct # to the manager of Cox field service in my area. I contacted him and he told me that they did another upgrade and now it requires a primary and secondary DNS Server. I entered the info, and without rebooting anything, it started working again. I operated like that for 24 hours without issue, then I removed the DNS Server info and the connection went out again; so now I leave the DNS server info in place until something changes again. I have no idea if this info is local to Tucson AZ so please use with caution. DNS Servers: 8.8.8.8 and 8.8.4.4 (NOT IPv6 DNS Servers).

Thank you. I live in Tucson too and will try your DNS #'s. I've been dealing with drops for 1 1 /2 weeks and suspect it has something to do with Cox's new digital only roll out. Will probably be dropping them like a bad habit soon anyway, but hopefully this will get me through to that point! Thanks!

I had issues with my nanny cams, so i went back to the default settings EXCEPT i left the DNS server info in place

Configure IPv6: Automatically

IPv6: Native

Enable IPv6 Connection Sharing: box is checked

but i left the two DNS servers

8.8.8.8

8.8.4.4

and it has been working with no outages since 3/16.

I'm in Okc and am also a Cox customer experiencing all of these problems. I have called Cox multiple times and now have started calling Apple. Both blame the other for the problem. I have watched my internet speeds go from 60 mbps to 6 mbps (today) and the connection drops regularly. Cox came out, replaced the line, said the readings were great. Of course, nothing changed. I finally spoke with a rep who mentioned the IPV6 issue and we changed it to Link Local Only. That did not correct the issue and the problems are still occurring. The last call I had with Cox, they suggested renting a router from them to fix the problem. Seriously???? This is so frustrating and no one seems to have any answers.

After reading your post I tried your settings and so far its been a couple of days and there has been no dropouts

I can verify that since switching IPV6 support on the Airport Extreme to Link-Local on March 5, I have not had any additional issues with dropouts. It seems to have resolved the issue. Based on what I'm seeing here I'm getting the sense that if people are experiencing dropouts purely due to the IPv6 rollout this change will resolve the issue (until there is a better fix that allows IPv6 to be supported on the external connection).

It is possible that in some cases there are multiple issues at work, not just this IPv6 rollout. In those cases this change may not entirely resolve all connectivity issues. In my case the IPv6 related issues never caused any speed issues. That sounds like something that would be more indicative of potential signal problems, or maybe just issues with Cox's backend at a specific location.

My understanding is that using Link Local only is only a temporary workaround and thus not an ideal way to connect so it takes longer to resolve the connection. My speeds were still good, however I could see it took a bit more time to resolve websites. My connection then started to drop completely after a month of using link local only so I added the DNS servers suggested to me by the field manager I was working with.

IMO, this is absolutely a Cox issue. My AE was working fine for years before the Cox upgrade. I did some checking and found my issue started the day after the upgrade in my area. Cox should have ensured that ALL routers were compatible prior to the upgrade and/or loaned AE customers a router until there was an Apple upgrade to make the AE compatible with Cox upgrade.

Cox dropped the ball on this one and should be accountable.

My advice to others having this issue....

If the workarounds described here are not working for you....Be a squeaky wheel. I contacted the BBB in my area so it forced Cox to take notice. I also demanded and received credit for the months I had no internet service. I spent many hours and days on the phone with support chasing ridiculous solutions such as removing all devices from my network, etc. It will take me many hours to put everything back and configure properly. I also registered a complaint my state utility/corporation commission. These complaints managed to get me a direct line with a local field service manager, so i didn't have to waste time with Level 1 or Level 2 support. Because of this contact, I texted him and got the DNS server info to try so I was not down for more than a few minutes.

You DO need to attempt to resolve the issue first by following the chain of support. However you can bypass Level 1 support and get cases logged with Level 2. Demand that field service come to your house (at no charge to you) to exclude all potential hardware issues (in some cases, there are other issues going on that could optimize service but have nothing to do with the IPv6 upgrade issue. i.e., I used to have Cox phone service, the box was still connected and not properly bypassed so field service completely removed it from my cable network).

I have been a loyal Cox customer for over 13 years and this is no way to treat customers. I rely heavily on the internet for nanny cams and home security and I pay for that service. I expect to get what I pay for. Cox dropped the ball on this and didn't seem to care about its customers using AE and pointed the finger at Apple and left us up the creek without a paddle.

So if you are not getting the help you need, make a fuss and get noticed.
