[Internet] Is this good or bad line stats?I just recently switched to 150/15 and can't seem to saturate my connection with any kind of download despite being able to do a speed test and showing 160/15. » imgur.com/UmF7KEN |

That's probably because the downstream signal strength is not good. The closest to +/- 0 dbmv is optimal. » Adelphia High Speed Internet » FAQ: Acceptable cable modem signal levels. |

There's nothing wrong with the cable line, those stats are good. Also, if cable signal was sub-optimal, it would reflect on speed tests as well since it would have nothing to do with routing or application implementation. Try an Ubuntu torrent: » www.ubuntu.com/download/ ··· ownloadsRealistically, there isn't a lot of scenarios where a single download needs to a full 150Mbps. |

You'll find that, at least in my experience, that downstream power levels are usually within +/- 2 dbmv on the Rogers Network. Can't speak for the TPIA crowd. |

Rogers Retail or TPIA makes no difference, it is the exact same physical infrastructure. Rogers goes by +11/-11, but the spec is actually +15/-15.
The OP has no issue with his DS signal levels. |

How come you are only having 9 Port IDs for the download streams?, I'm having 20 Port IDs, each of them is having +1~+4 dBmV, same 150/15 plan, CGN3 |

There's nothing wrong with the dowstream signals, certainly. There is an anomaly with the upstream ... Not out of spec, but unusual ... There's about 5 dB difference between the signal on upstream port 3 compared with ports 1 and 2. Normally these are within about 1 to 2 dB of each other. On the early channel bonded modems, a difference of more than 1 dB would actually result in failure.
What is in your modem's log? |

What is in your modem's log? Where would I find the log? I have a splitter attached to the line and I'm wondering if it might be causing an issue. |

OK, I didn't read that you were getting 160/15 ... presumably you're on the 150/15 tier.
How are you trying to "saturate" your downstream? It's very possible that you are just expecting more than the sites you're downloading from can deliver. |

I would suggest that OP try the following. Fire up a torrent client and download 4 Ubuntu torrents simultaneously and it will max out your connection in mere seconds. » www.ubuntu.com/download/ ··· ownloads |

assuming nobody downloads from him at the same time, saturating his upload. |

Even with 9 downstream channels should still work ... the fact that a speedtest gives 160 Mbps, it's nothing to do with the modem. |
