West Des Moines, IA | Leveraging DOCSIS 3.0 I've been experiencing intermittent outages for the last 2 months now.
After a service call resulted in a embarrassingly simple reset. (I know better.) I've been unplugging my modem about once a week for 15 seconds to restart it, and then also, restarting my router. Or at least doing a DHCP release/renew once the modem has come online.
I've begun to think it's the modem that is misbehaving. So I've been shopping for a new one, thinking at the least, I'll stop renting a modem. While I've been shopping I've come across DOCSIS and Channel Bonding.
At present I have a MediaComm Issue, SurfBoard SB4200, according to the listing on Amazon.com it can be upgraded to DOCSIS 1.1.
My questions are:
•How can I determine how many channels are available to me to bond?
•Is there a benefit, regardless of Updating to a DOCSIS 3.0 Modem? |

| there is your issue... that modem is way too old. You need at least a SB5101U for docsis 2. i would take it back and just go to walmart and get the other one. |

Do you have the 20Mbps or faster?
If you have 12Mb or the 3Mb there is ZERO reason to get a D3 modem at this time. |

yes, no reason to go to a D3 modem if you don't have online max or ultra 50 |

dwcouch - as the other have said - unless you are going for the Ultra, there is no reason to get a docsis 3 modem. as for the channel bonding, that is nothing you need to worry about. the channel bonding is how D3 achieves the higher bandwidths.
DoctorX - that modem is still being issued by our warehouses to be used; the age of the modem is irrelevant, it comes down to its capabilities, and that model has been certified to work - I just put in two last week, have no issues with them. |

• DoctorX - I wasn't asking if my modem was working or not. Or what Modem would provide DOCSIS2 or better. And I don't shop at Walmart.
• IowaMan, Boss302_1970, & StreatorGuy - Thank You. I am on 12Mb. I suspected it wouldn't make a difference.
• StreatorGuy - I wasn't worried about channel bonding, because I'm curious, I wondered if there was a way to determine if there were channels to bond. The research I did on DOCSIS and the understanding that it is used to achieve higher bandwidth is what prompted me to ask the above questions.
UPDATE:
I've contacted MediaComm and addressed the issue. I'm going to go ahead and purchase a Modem, return the SurfBoard and drop the $5.00 rental fee / month. The rep also confirmed DOCSIS2 is pretty much the standard anymore and that DOCSIS3 would be of no benefit unless I upgraded to Ultra50. He recommended Motorola or LinkSys. I have chosen to buy the Motorola Surfboard SB5101U.
•Amazon.com $46.95
•Wal-Mart $79.99
Again, thanks all for the replies!

Dubuque, IA | It has been reported on this forum that some MC market areas are using DOCSIS3 to implement the 20 Mbps MAX service to customers, as it gives the head-end the opportunity to get customers on different channels than those used by the more congested Intro and Standard customers. So D3 is no longer strictly Ultra and above. |

[/BQUOTE :The age of the modem is relevant as well as the condition the modem is in as well. |

Just because Mediacom is still issuing 4200s does not mean those modems are not junk. BTW they are. If possible I tag them as defective without ever using them.
Junk modems showing upstream much higher than actual and overall having poor performance.

I have not got an answer yet but I have a SB6120 on 12 meg service and my bonding light...second one down is now blue.....and modem interface is showing 4 bonded channels instead of 1 channel like it used too

| well most CSRs will tell you otherwise but from my field experience DOCSIS 3 modems when used for standard 12 Mbit service will lock additional downstream channels. 3 or 4 depending on the area and they will utilize additional bandwidth despite people saying otherwise. since most DOCSIS 3 areas are new and utilization is fairly low this will almost always result in eliminating the peak time slowdown.
so better service for $5 less a month? i dont know about you but it sounds good to me!

as it looks like it is doing with me....but everyone is telling me we do not have docsis 3 yet.....but I am still showing 4 bonded channels
if you look at the 3rd post here »[IL] Southern IL HSI slow?
then go to the last page you will see the change from 1 channel to 4....with the same SB6120

Des Moines, IA | yea you can benefit from a DOCSIS 3 modem because of the low utilization it will benefit from the peak slow down times because of the extra channels |
|
| I pay for 12 MB and I just set up my DOCSIS 3.0 Motorola Surfboard 6121, cost $109.99 at the local bestbuy here. (Des Moines Iowa)
and my speedtest went from 12-14 MB/s to 26-30 MB/s.
And the modem itself confirms that the downstream uses bonded and the upstream uses single. Whatever the correct terms are.
So I can confirm, that it does help!
Although it really depends on your location, because not all locations benefit from it! |

Des Moines, IA | it depends how many people in your neighborhood (card at the headend) how much you actually gain but right now DOCSIS 3 Utilazation is pretty low |
