Re: Getting Comcast, need some help
said by nate1234  :Not exactly.... what tier do you have again? 16/2
At least that's what I'm signed/paying for. |

This is what my modem stats say:
I also did a few tests, I hope these a okay results:

Glad to hear your internet service is treating you well.
Since you are in a DOCSIS 3 area you should be able to get smething higher than 16/2. Though overprovisioning o the speed and lengthy PowerBoosts (at least these days) may make 16/2 a decent enough option.
I'm not sure where the other posters got the actual figures for the business tier soft caps from, however I know that eventually Comcast will tell you to move up a tier or three if you push too many bits over a cable connection, commercial or not. 250GB is the residential soft cap. Commercial is significantly more, but it's still not a dedicated connection (MUCH more oversubscribed than FiOS...which in GPON areas is actually UNDERsubscribed). |

I don't know why, but that's the fastest option they offer me for a commercial connection; again I'd go for a faster tier voluntarily if they offer it. |

Those results are exactly where they should be; Comcast tiers are actually overprovisioned by 10% on download and upload speeds to make sure people test at the speed tier they're buying. So theoretically you can do 17600 kbps all day long on your connection (after PowerBoost wears off).
Modem levels look to be right where you want them to be, and channel bonding appears to be working despite not having a DOCSIS 3.0 tier (yay for DOCSIS 3 modems). That said, doesn't look like you're getting any speed boost from dual channels, though having two means you'll be more likely to get 100% of your rated speed 100% of the time.
What's interesting is that your upstream modulation is DOCSIS 1.1 rather than DOCSIS 2.0. I've never seen a DOCSIS 1.1 upstream channel along with bonded download channels, but that's what you're getting. Maybe try rebooting your modem to see if it'll grab a higher-modulation upstream channel. If you're actually in a DOCSIS 3.0 area you should be getting a DOCSIS 2.0 channel and 5+ Mbps of upload bandwidth (here the number is around 8-11 Mbps on my non-D3 modem). |

So I just rebooted the modem; it doesn't look like anything has changed:
Should I call Comcast about the DOCSIS 1.1 channel or is it not really an issue I should be concerned about? |

| It isnt really DOCSIS 1.1 modulation, Comcast switches between 16, 32 and 64QAM based on congestion and signal noise. I have the 22/5 service and am on 16QAM Modulation, and get 8-9mbps up (Powerboost). Comcast is currently rolling out 64QAM in all markets, and then Upstream channel bonding. |

What does the "[3]QPSK" along with "[3]16QAM" mean? I know what QPSK and 16QAM are, but what is the the "3" part, and mentioning both modulation schemes? |

IM ComcastSteve ...it's shouldn't be DOCSIS 1.1 for upstream. I had this before on my Extreme tier when I rebooted the modem. All 4 Channels were bonded for downstream and upstream changes from DOCSIS 2.0 to 1.1 and my upload speed became 6 Mb/s instead of 10 Mb/s. ComcastSteve fixed it and everything running smoothly and faster than b4.
And mine still 16 QAM for upstream but getting 1.3 MB/s constantly |

Moorestown, NJ | he is only on 16/2 - 16QAM is fine, it can handle 10.24Mbps |
