[OK] Internet connectivity losses as well as digital cable drop

Our internet services have done very well since moving in though there have been some issues for certain digital cable channels from the beginning. I don't remember the exact issue but multiple channels would lose signal and it had something to do with one frequency band. Multiple techs came out and though the problem has NEVER went away the channels were available with minimal drop outs. Now the digital cable and internet both are having dropouts. I have been running PingPlotter for the last couple days and it seems that this is happening mostly in the afternoon and evening hours.

Signals in the modem are good as far as I can tell but I am trying to see if there is a signal change when an event happens. But catching it is a pain and even though it's only a few seconds at a time it is really frustrating for VPN and Gaming.

I thoroughly despise phone support as they all treat you as a no name person who doesn't know how to turn the computer on and make it work let alone configure a network so this is my first and only stop. If a call needs to be made for more to be dealt with my wife will have to do that.

I was using a Motorolla Sufboard 5101U but when the problem began I switched to a newer Docsis3.0 Modem I had as to make sure the problem was not related to the older modem.

The problem is still occurring and when it does generally the digital cable goes out at the same time. I was initially just having periods where I would notice an increase in lag and ping while playing World of Warcraft but things have steadily gotten worse.

You can see the dropouts from a 24hour period in ping plotter here »files.ventshop.net/Graphics/stuf···ogle.png

As you can see my router stay up and a separate ping to the modem shows it is functional as well but anything beyond that is dropped. I ran a ping -t to the modem to verify that it was not a part of the problem.

Below is the data I collected form the logs.

I know my DPC3010 likes to bond only 1 channel after problems until I reboot it later. Like you, I come up with only 1 channel bonded, but still good/same signal levels. very odd...

My modem went back to 8 channels within only a few minutes and at the same time I often have digital cable dropouts. Most of the time this happens for one to two seconds but in my experience this is a precursor to more issues that will only get worse. I know there have been some other problems in the OKC metro area but some of the problems especially with the digital cable disruption is likely due to something more localized. There have been line techs out who have made some adjustments to the signals and that did help but the problems have continued.

Went so far as to have one tech supposedly come out never make contact say everything was fine and then get billed for it to have the same problems and another tech be out two days later and see the signal issues to have someone else come out to actually make some changes.
