2 edits | [TWC] Road Runner Intermittent problem. Techs have a hard time.
Hi I'm from hawaii in the island of Oahu. I live in the Kalihi area.
So here's whats up. I have windows XP and I have a Webstar DPC2100R2 modem, thats the only one they give.
In the hours of 9pm-12am my road runner connection will act up. Either or will happen. The cable light will go off and start flashing, while the PC and power light stays on, then all lights will go on as it is starting to sync up again. OR The PC light will just go off and the Send/Receive lights will go off also, while the Power and cable light stays on.
When one of those issues happen it will start to reconnect itself real quick. It is annoying because it will cut me off from online games or downloading youtube vids.
Here is what i tried:
Exchange modem - no work
Change Ethernet cable - no work
Change NIC (network interface card) - no work
Tried different outlets - no work
Tried every setting in the speed/duplex - no work
Had road runner tech come to my house - NO WORK!!
All the tech did at my house was change splitter and add some type of filters on it because he said the t.v. downstairs was getting feedback. They are sending an area foreman to check out the area on the 29th, but i was wondering if anybody had any idea.
And its not my signal because its great. Here it is:

Just based on the light activitiy, the problem is your cable signal. Your modem only shows 2 out of about 6 of the needed cable signal stats. The TWC techs should be able to get better stats than your modem shows just looking up your MAC address. They really need to look at the Downstream SNR, Downstream pre/post BER, Upstream SNR, and Upstream pre/post BER to qualifiy your signals as good or bad.
The feedback comment alone makes me think you have a serious ingress issue which would also affect SNR of the modem. Hopefully the foreman can get a better handle on your signal problems.
Does your modem have any logs you can post? |

The feature is not enabled on the modem they give me. Road runner must have turned off the log. I asked them if they could check the log, but it seems like they try to ignore me when i try and say that and bring something up. |

Here is my stats, although I'm in NH |
That should get you full access to the modem for a few minutes, you still will not be able to see the upstream SNR, but will be able to access logs and the rest. |

Roadrunner doesn't disable the features on the modems, they come with access disabled by default. The provider could turn them on again if they write and push a custom boot file with that feature switch enabled, most don't because it's non-standard and a hassle.
Keep scheduling calls until it's fixed. Basically become the "squeaky wheel"... |

1 edit | Yes i will keep scheduling, but i always have to wait a week or 2 weeks just to get someone out here. It takes so long everytime and its just hard.
My gf takes online courses between those hours after work and its just been hard on her this past month because she has to stream videos sometimes or do research. It seems like the problems happens is when she is loading a page or loading a video. Or when i play my PC games, but always between 9pm-12am.
Any former/current cable techs seen this type of issue before. I'm so desperate right now, i might have to talk to a manager when i get home, im at work now.
I will try that signal thing whiteyonenh and post it. |

When your service is about to go out, do you think you can try and access the modem to see what the current values are? This could be an indication that it's a wiring problem in your home.
It can drastically show a difference, where your upstream, and downstream spike to cause a de-sync. |

Very good point, and something I didn't think about, good catch. I'd also like to see what the signals are right around the time that they normally disconnect. |

Camarillo, CA | Yeah, I had to think about it for a bit. But, services can show fine when idle, and then of course as soon as ANY load starts up, it can immediately de-sync you by the power level creeping up, and then BAM! It's out! |

I see that there are a number of T3 errors in the log. A few T3's every so often are OK, but a lot of them could indicate that you have a noisy connection. |

I checked the signal, during those hours i get dropped. Nothing suspicious enough to cause the drop. I even checked the signal while downloading something. Although all the numbers change dramatically when the modem is dropping, then resyncing...but that is expected. Then numbers go back to normal when everything is synced up.
daveinpoway maybe you are right, i might be getting noise in my connection in those hours maybe. All the wiring looks good in my house, must be something outside of my house. I live in an apartment building, maybe my neighbors are doing something to cause this.
I shall post a youtube video on what my modem is doing. I can't do it today because its my grandma's birthday, but i will do it tomorrow or maybe tonight if i get back home in time between those hours. |

it couldn't be a bad power supply on my computer could it? I remember I had to remove the cage thing in front of the fan because it was hitting it. Seemed like the power supply fan lowered. Also notice a kind of whistling noise coming from the power supply sometimes. But i don't receive symptoms of a bad power supply like random reboots or BSOD. Can anybody rule this out from my connection problem? |

I think i can rule out the power supply because why would my power supply only act up during those times. Plus when the modem desyncs, i get the "Lan unplugged" message. Then when it syncs back up right away its says Lan connected.
So i tried putting a router in between my modem and computer. Everytime the modem desyncs, i would NOT get the "Lan unplugged" because the router is still connected to the computer. But visually i can see the modem desyncing and then resyncing. In the middle of the desync and resync i can't go online. So i can rule out power supply because my router can stay connected.
But anyway, last night...i went online between 9pm-12am and i haven't been dropped even once. Maybe the problem fixed itself, but im not convinced yet. I will be more convinced when i get stable connection for at least a week. I have the foreman scheduled earlier this time (this thursday). I will keep you all up to date. |

Apparantly the problem just happened again, this time not in the hours of 9pm-12am. My girlfriend just called me at about 1245pm and told me the internet did it again. Just to be sure i will change my power supply. If anything hopefully the area foreman can fix this issue tomorrow.
I remember when the problem first started sometime near May 24th. It would do it before 9p-12a, and it would do it anytime it wants to. But lately it was just doing it between 9p-12a. Now it did it at 1245p. I guess i think it just happens between 9-12 is because thats when i use the internet the most. But my gf is home and now it has happened to her. |

Sounds like a signal problem, really. Bad hardware on your computer wouldn't cause the modem to lose sync or reboot itself like it's doing. So, we're left with bad signal in general, or bad cable. Bad power from the outlet the modem's plugged into might also be a factor, though less likely.
In short, problem exists between modem and ISP.

1 edit | Cable foreman came by today, all he did was isolate the splitter (something like that). But when he did that my upstream level went up to 51.3 dBmv, i told him thats kind of high, but he said as long as its under 52. He did check the wiring outside and he said everything looks normal.
But the cable foreman called the office and asked them about my history on my modem and they said i had a bunch of T3 and T4 timeouts. I overheard that i had over 1000 T3, T4 timeouts and its increasing. So he told me it could be something in the head end. They will call me back in 4 days to follow-up.
I hope what he did with the splitter will fix this. But I don't like how my upstream increased because of it. I remember when i first signed up my upstream was at 61 dBmv, but it just decreased on its own, down to 45 dBmv at one time.
I'm not liking this, but at the same time this is interesting because i want to see whats causing the problem. I'm betting its guaranteed a headend thing. I think it started happening when that UFC fight between Lyoto Machida and Rashad Evans. |

The vast majority of upstream problems are caused by noise getting in the system or excessive attenuation. Damaged cable, damaged equipment, loose connectors, illegal connections, and failed equipment are the biggest causes.
Rarely is it a headend problem.
P.S. I've worked installation, service, dispatch/routing, tech support, plant maintenance, and headend for a couple different cable providers. |
