Re: [OS X] Dropping Internet Connection using Open DNS
okay, I hooked up a Netgear router thinking my APE was the problem and the same thing happened (dropped connection). Strange think is it always happens at night between 8-9pm. Could it be a problem with my modem? I know it is one from Bellsouth and I have had it for 10 years. |

said by Heelfan71  :I had my modem in "bridged ethernet" mode and the APE in PPOE. I just switched it so the modem is PPOE and APE is now ethernet. I was reading somewhere about APE having problems with PPOE for some people since Leopard came out. Hopefully this does the trick. never had any disconnects when I had my modem set at PPOE and the APE as Ethernet. Switched it back to Modem=Bridged Ethernet and APE=PPOE and I lost connection within 5 hours. Wondering if I just have a faulty APE or it is something with my modem. |

OK...this is just weird. I pulled out an AirPort Extreme that I haven't used in a while and swapped out the Time Capsule with the AirPort Extreme. The same thing happens with both the TC and the AE. If I set the WAN port to 10/Full or 100/Full my internet doesn't drop, but my speed when I do a speed test is less than half what it should be. If I set the WAN port to 10/Half or 100/Half my internet doesn't drop and when I do a speed test it's right where it should be. If I set the WAN port to Automatic, the speed test is right where it should be but my internet drops at least once a day. When it drops I can get it back by either resetting the TC/AE or (in the case of the TC) clicking a couple times on the Renew DHCP Lease button in the AirPort Utility.
I've always had the WAN port set on Automatic and never had any problems until about the time this thread was first started (about three weeks now, I guess). On top of swapping around the TC and AE (and having the same problems with both), I've also changed out the ethernet cable between the modem and the TC/AE. So...I'm guessing there's some sort of craziness going on with my cable modem. |

I don't know either. But the option isn't there unless I switch to 'ethernet' |

PPPoE is ethernet. Point-to-Point Protocol over Ethernet.
Not sure why you wouldn't be able to change the WAN port setting when using PPPoE. That WAN port setting just configures the speed at which your modem and the AEBS talk to each other. That doesn't have anything to do with the PPPoE protocol that I'm aware of (but I could be wrong). You should be able to set it to 10/Half, 10/Full, 100/Half, 100/Full, 1000/Full, or Automatic. When it's set to automatic, the AEBS figures out on its own which speed it needs to talk at. |

You don't need to use the DNS Updater. Any service provider I've ever had my ip address has NEVER changed. Once you configured your AEBS with OpenDNS.org's DNS Servers there's no need to mess with it again unless you reset the router. |

I turned off IPV6 and haven't had any drops since. Only been 24 hours so we will see.. |

no, I will try that. Also, I am wondering if IPV6 needs to be on. I turned it off. |

I think something is wrong with my APE. I keep getting drops (no time capsule). Resetting the APE always fixes the problem |

said by scots :Hmmmm...just found something which mentioned the WAN port on the TC/AEBS sometimes has issues with some cable modems and the internet dropping. It suggested setting the WAN port on the TC/AEBS to 10Mbps/Full or 10Mbps/Half rather than Automatic. I guess I'll give it a shot and set it to 10/Full, although I don't see how this could be the problem. I've had the TC for about 11 months now, and there's been no change to the cable modem or anything else on my network since I first got the TC. This all just started happening last week (or was it week before last?), so not sure what could have all of a sudden happened to start causing this. Well...looks like this may have been the issue rather than my last post about the DNS proxy dying. I had originally set the WAN port to 10/Full, then changed it to 100/Full, and had no drops. I changed it back to Auto and my internet dropped again last night. I tried going to a web site via IP address rather than name when the internet dropped and it wouldn't work. Set the WAN port on the TC back to 100/Full and it's been working fine again. Nothing's changed about my setup since I first got the TC a year ago, so not sure why it would all of a sudden start having an issue with auto-negotiating on the WAN port. |

Just found this on the Apple support forums where a few people are having a similar issue:
»discussions.apple.com/thread.jsp···#8306744
From what I read it looks like the DNS proxy is dying in Time Capsule, and one person has had the issue happen on 3 different TC's. People in the thread say that when the internet "dies" they're still able to get to places on the internet if they use IP address rather than name. If mine dies on me again I'll try going somewhere via IP and see what happens. |

said by scots :Yeah...I know all that. I work in computers/networking.  I've been trying to think of something that might have happened since all this started that could have caused it, but can't think of anything. I'd suspect the TM then. Can you get your hands on another router to use for awhile to eliminate the TM?

Yeah...I know all that. I work in computers/networking.
TWC came out to my house about 2 years ago and replaced EVERYTHING...the cable modem, all inside wiring, outside wiring, cable from pole to house, and a bunch of stuff on the other side of the pole too. My internet has been rock-solid and problem-free since they did all that.
I've been trying to think of something that might have happened since all this started that could have caused it, but can't think of anything. All my gear is on a UPS, so a power surge or something like that is very unlikely. Nothing major in the logs in the cable modem either, and none of the events in the cable modem logs have occurred at the same dates/times that I've lost internet. |

The next time you experience this, try connecting to your cable modem via its web interface; just because your modem lights are flashing normally doesn't mean your WAN connection is up. Then I'd turn on your Mac's firewall and connect directly to the modem, but I'd try these first:
Check the modem logs for lease requests; your WAN connection could be in suck mode for any number of reasons.
For kicks, clone the TC's MAC address in the router's clone config (should have it somewhere). Most, if not all, cable companies are beyond this, but it's worth a shot.
Reset the TC - have you done this?
PS: I run OpenDNS as a primary DNS on the clients and the router as the secondary. IOW, I don't override the modem's DNS - leave it as is. I don't use anything other than the IP addresses, I don't use their services (don't even know what they are!)
Good luck. |

The point of plugging directly into the modem is to bypass any possible issues in case the TC is to blame. If your Internet connection works without issues when your Mac is directly connected to your modem, then you're able to isolate the problem further.
It could be that your TC isn't headed South, but you have to rule out certain factors in order to get closer to the actual problem.
Sometimes these issues can be frustrating and time consuming, yet in order to get closer to the real issue, you need to take some rudimentary steps.

I'll try plugging directly into the cable modem if it happens again, although I don't think it's the cable modem. All I have to do to get the internet back is either power-cycle the TC and nothing else, or go into AirPort Utility and click on the "Renew DHCP Lease" button a time or two. Don't have to do anything to the modem. Whenever this happens all the lights on the cable modem are on like they're supposed to be. In the past if the internet has gone out due to some issue with the modem or TWC, not all the lights have been on or lights have been flashing/cycling on the modem. |

Give it a shot and see what happens.
My first router was a Dlink. Worked great for almost a year and then just crapped out on me.
Initially, I thought it was the pc, Internet connection or the modem until I finally narrowed it down to the router.
To better isolate the issue, try bypassing TC and plugging your Mac directly into your modem - that will rule out some possible causes.
