Re: [OK] Another day, another Cox outage Not with the Cisco I can't.
In the Moto, I would have a T3 rarely (1x/week?) but that's it, nothing else.
No, it was including the router. |

said by bchandler02:That was this tech's thought as well - it is only bonding 1 upstream in this area and it may be losing/searching on the upstream side.
That sort of activity would show in the modem logs. Can you post a screenshot of them?
BTW, you PingPlotter graph doesn't show your router inline. Is that PingPlotter graph with the PC directly connected to modem?

Two is one, one is none. If it's important, back it up... Somethimes 99.999% availability isn't even good enough. |

said by bchandler02:Yep, when they redid everything late last year they had a multimeter out reading all kinds of levels making sure everything was in check, and it was.
But did they do it for a period of time? as from what you have said, it's not a constant issue, but happens often. |

They (and CT1 here) have told me that I am the only one in the area being impacted, all my neighbors stay online. But, they can't find anything wrong here, and it has all been replaced anyway.
Do you know if they have tested the lines at your house, to see if there is anything pushing noise/voltage threw them? Because a home noise/voltage issue could easily cause a problem. |

said by bchandler02:Yes, they all go to 100% loss. I cannot ping the modem interface during the drops either.
In the last 20 minutes, I lost the online light (and connection) for about 30 seconds, followed about 10 minutes later by a full modem reboot.
Well that sounds like a upstream noise issue in your area. As I am sure if there was a noise issue home side causing this problem, one of the tech's that has been to your place would of found the problem. Still it's the job of your local cox guy's to find the source of the issue, and they should be able to lookup modem's around you, to see if/how many others are being affected by this problem. Because if it's a home side issue, people around you modem's would be unaffected by this problem. |

With pingplotter, does all hops go red when the dropouts happen? the image above show's hop 3. |

And I know it's been covered already, but here are my signals. They are the same with either modem, they wanted me to leave the Cisco on for now for the logs since he saw it happen with this modem. (Long term, I'll likely go back to the Moto) |

| reply to lilstone87
Yes, I've been using pingplotter. During "normal" operations everything looks perfect, great times, consistent, etc. Then, I go to 100% packet loss during the outage, and then right back to normal. |

Sound's to me it could be a noise related issue within the node, and it's causing the modem to lose sync, but not to the point the modem reboot's. Have you tried running traceroute's for a long period of time? to see what it shows when the internet is working, and not working? |
|
| reply to bchandler02
Yes, happens with or without.
There is a silver lining to today's problems. Not 2 minutes after the tech walked out, it did it again, this time on the Cisco modem. I ran outside and caught him and he came in and saw it first hand. He was on his tablet and said the modem did not show as online despite him staring at 4 solid lights. After a few phone calls, he said the people that need to look into it are out to lunch and he'd get back to me this afternoon. |

So you have a router connected to the modem?
Does the problem happen without the router connected to the modem, just a single PC? |
|
| reply to bchandler02
Tech just left, no problems found (surprise?).
We swapped back to my old 3010 to see if it makes any difference. |

I just called in as it happened again (2x in 30 minutes).
At first, the tech could not see the modem. I rebooted and he was able to see and said he saw the problem as the modem switching frequencies. He wasn't sure why - signal or line problem most likely - but has someone coming out in 2 hours, so at least hopefully they'll catch it during the act for once.
What would cause it to switch, and if I am bonding 4 channels, shouldn't it be able to maintain connection better via multiple channels? |

Yes, the modem must always be rebooted when connecting a different device to refresh the CPE bridging table. Our ability to connect to the modem remotely will not be affected. |

Also, no, I cannot ping it. I can continue to ping my router, but not my modem during the problem.
It's as if the modem goes offline (but lights don't reflect this). However, I found it very interesting that the agent could communicate with the modem to reset it yesterday. |

| reply to DrDrew
Well that test doesn't work. The modem will not give a new IP address without a reboot.
Apparently I'm going to have another day of hell fighting this thing today. |

I am using a desktop that is hardwired and a laptop in a docking station that is hardwired. Both run through my UPS as does the networking gear.
When they were out in November, they did have a multimeter out looking for any electrical noise on the coax and didn't find any.
Interesting theory you have - next time it happens, I'll grab one of my other laptops and check it. |
