1 edit | Downstream power level too low? I don't think I've ever seen it this low. What could/would cause it to drop? (I do not use cable TV service)
What sort of issues can arise from this? (I've noticed slower speeds, and much higher pings...but not sure if it is due to the low power level)
What is a good threshold for that level? Everything else seems fine.
Motorola SB5100
Downstream Value
Frequency 663000000 Hz Locked
Signal to Noise Ratio 39 dB
Power Level -2 dBmV

1 edit | Those are great! 
+10 to -10 is the normal acceptable range 0 being ideal. |
|
| Hmmm. Ok. I am used to them being around -10 to -12 range...when I noticed the -2 tonight I started poking around...well, needless to say there seems to be a mixed bag of opinions - some said don't 'like to go below -7'...yadda.
Thanks for the quick reply! |

| Ah, that helps. Thanks.
Totally unrelated - contractors are laying new fiber up down our streets, have my sidewalk and some of the yard painted to be dug up (cable box by me)...would this be Comcast laying fiber? (I know it's fiber because I asked one of the workers when driving by "what are you guys doing?" 'Laying fiber cable'...I had to drive off before I could ask anymore since traffic was coming up).
We also have a couple of QWest boxes around (noticed one was marked DSLAM).
Anyway, just curious...and if it is Comcast...why would they be doing this? |

you wouldnt want it dropping more if your at -7. but -2 is not dropping from -7. that is improving. |

My RX is within the recommended range, but I have seen it anywhere between -2 and -4.5 is that a fluctuation?
And can power cables running alongside the coaxials cause interference?
My connection runs at advertised speeds, so no problem there ... just curiosity  |

Umm, -2 is higher than -10 or -12. a power level of -2 is over 800% stronger than a power level of -12 |

I'll trade you my +9 for your -2  |

Well, my 'new fiber' that is getting placed in the ground around here continues to be a mystery. I read something on the front page about Qwest stating 'they're not using it' (or something similar)...so...hmmm...
We do have large Verizon corporate office out here...maybe it's them.
Would Comcast need fiber to implement DOCSIS 3? I had thought it's possible through their current infrastructure, coupled with some backend changes?
The funny thing about where I live is that it is a tech oriented town (Seagate, Quantum, HP, Cypruss, etc, etc, etc) so anything new/better would be eaten up out here. I've always been surprised that most companies (ex: comcast, or whoever) don't look to a 'second city' such as this for test market. |

Just an update to the fiber mystery. It is Qwest, and since Colorado Springs is listed as a 'test market' I would guess it is in lieu of FTTN implementation around here. |
|
| Qwest isn't serious competition to Comcast so that's why you won't see DOCSIS 3.0 in CO anytime soon. |

It might not be a fluctiation. CC has been modifying their system in my area for maybe a month, and my signal levels have been getting better incrementally during this period.

| My Downstream Power Level's were always around 0 to -2. As the weather is starting to warm up my signal has dropped to -7. I wonder if it goes any lower should I be alarmed? I read that anything below -11 is not good. It seems I'm approaching that boundary. |
