Re: Modem or Signal Strength
I think amping that up wouldnt do anything. Your -19 for a reason somethings wrong somewhere. Are they 2 way splitters or a 3 way to a 4 way or something ? try figuring a way to have it just go thru one splitter just for a night and then do all your tests and see the difference. do you have rg6 cable to the modem or rg59 cable ?

Would an amplifier help me with my downstream power level? It is ranging from –13 to –19, depending on the time of the day. |

Welcome to the Comcast Forum
According to the timestamp in your logs, your modem became operational at 6pm tonight? Hmmm...
You're having trouble acquiring an upstream signal. When you got sync, your upstream powerlevel was 54. When you posted your signals, it was 51. What is it now?
I've never even seen that "RR Abort" error before, but it can't be good.
When a modem is trying to lock onto upstream what it does is it keeps increasing it's power level one by one until it achieves lock. This is why if you goto the modems signal page as it is booting and keep hitting refresh you will see the upstream power level rise.
RR abort occurs when the modem is trying to boot and it reaches 58db without acheiving lock. It can't go any higher so it aborts its search and drops the US back to 0 to start again

Somehow, I think it's NOT the modem. That's wacky upstream signal behavior. Generally, signals will vary a bit but not like that.
Do you own or rent?
Did your downstream powerlevel or SNR change at all? |

My current upstream power level is 45. |

Yes, there are two splitters in the line before the cable modem. It has been that way since Roadrunner was installed years ago. Attached is my log info.
Thanks |
