Your upstream is quite high, though your downstream power and SNR are good. |

I wouldn't exactly call those "GOOD".

Yes, but after two calls to Comcast I understand that my Upstream is "good" and "no" they won't send someone out.
And, in fact, my connection has been Very Stable (knock on Wood) for the three weeks it has been up.

And, in fact, my connection has been Very Stable (knock on Wood) for the three weeks it has been up. Up until recently, my signals have been terrible and yet my connection has been completely stable. The presence or lack of stability doesn't necessarily mean the line stats are good or bad.
My current signals are closer to what would be considered "good":

I've just read up on signals and from what I understand, these would be considered "pretty good," yes? Though I'm on "Blast! 50" in Central, PA; should CH4 Upstream be "not locked" like that or am I ok? I do get the advertised 10 Mbps.

Sadly, our neighbors just got Comcast Internet too I believe(I saw a truck/Gateway SSID come up). There's only two others in our whole neighborhood with Comcast(One all the way down the street and one down the road) while the rest are AT&T U-verse. Darn you neighbors! They better have a horrible connection or go back! I want a free node :P. If more people switch to Comcast I'll cry lol.
Oh and karmaghost it's fine. It just means your modem is capable of 4 upstream channels but only 3 are available. I only have 1 in my area. |

| reply to ctgreybeard
Yeah, very few people have all 4 upstreams. |

| reply to Darknessfall
I see. I'm curious, from the information you provided, how did he know that you're the only person on your node? |
|
| Not sure lol. Maybe my stats were good or something. |

| reply to ctgreybeard
I'm curious, what's the best signal stats supposed to be closest to? |
|
| Good would be >35 SNR downstream. 0db power level would be ideal. (+-7 is perfectly fine) Upstream should be 50db otherwise you start to get into intermittent issues. The thing to remember is that signals fluctuate throughout the year so even though 52db is perfectly reasonable now, if it turns into 55db later you're going to have issues.
The one thing the modem doesn't measure is upstream SNR so it's always possible to have good power levels but have low signal to noise. I don't know exactly what numbers you would need but there is a difference between a clean 52db power level and a noisy one. |

How could that ever be known by the RF signal stats alone ? |

Yeah I know. That's why I said "closer to good." |

said by ctgreybeard:There have been some complaints about Comcast occasionally here. I just thought I'd post some GOOD stats and reliability. The problem with that 52dB upstream is what happens when upstream bonding is enabled in your area? The max limit for 3-stream is 51dB for 32 and 64QAM, 52dB for 16QAM. 2-stream is 54/55dB. You may have issues, usually that nasty T4 timeout problem. |
