| Re: [AZ] Cox Preferred HSI Tucson Slow Download, Fast Upload said by MrSmith :said by Jiggawatts :This morning, I am getting 22mbit down, 9mbit up from Cox: 20 times faster down than 12 hours ago. :| My receive power level seems to have shot up as well: I find this very interesting because I tend to get speeds of ~20Mbps down in the morning, and slowly throughout the day it declines. It is almost 1pm, and I am hovering around ~9Mbps down. I wonder if this is simply because more people get online as the day progresses, with the maximum number of people on around midnight. I guess since it is residential, this is possible, but it seems kind of strange. There must be some other reason. And I think I will stick to buying my modem online. I'm not going to give Cox MORE money because they failed me. It just doesnt seem right to me. They could just make current modems incompatible and force everyone to buy their merchandise, therefore increasing their profits... (and I'm not entirely convinced that this is not what they are doing) In addition to that, I don't live anywhere near a Cox store. I'm going to be really pissed if I buy it and my speeds don't increase though!!!  Well your speed is decreasing threw out the day because more people on your node is using the internet, and the downstream channel your on is getting hammered which result in speedings getting slow. The single downstream your on has a max of 38mbps of shared bandwidth with whoever in your area is using that same downstream channel. The benefit of D3 is more channels to be connected to. So on your D3 modem you will probably connect to at least 4 downstream channels. So then you will have 4x38=152mbps of shared bandwidth available to you. So when everyone in your area gets on the internet, there is a lot less chances of slowdowns in speed for you.
So I hope this helps you better understand what D3 is about and the benefit of using a D3 modem. I suggest if you order a modem online get a Cisco DPC3010, because its more future proof being a 8x4 D3 modem. I was just recommending getting it from cox because it will be easier to get a refund if the modem does not help like it should. |

Ok, this is what I was wondering, if DOCSIS 3.0 would help speeds during high traffic. I'm going to go ahead and order the Cisco you mentioned.
I'll post back once I get it with results. |

Ok, so it looks like the DPC3010 is out of stock pretty much everywhere. What is the next best modem? Is the Motorola D3 modem worth it? |

Well the motorola sb6120 isn't a bad choice imo. But its one of the first gen D3 modems which means its 4x4, so it can only bond up to 4 downstream channels compared to 8 downstream channels the Cisco DPC3010 can bond. Motorola has an 8x4 D3 modem Motorola SB6180, the problem is this modem is only supplied by the ISP, and only very limited area's of cox carry this modem. So most cox area's carry the Cisco Dpc3010 in there stores. I know you hate to throw any money cox's way, but if there happens to be any cox stores local to you. I would suggest going to one, and picking up the Cisco DPC3010. Because why buy a modem like the Motorola SB6120, which is older D3 modem, when you can buy a more future proof modem for same price. |

| There is also the Motorola SBG6580 modem/router combo; I don't think Cox sells it, but it is available retail (Fry's Electronics, Best Buy, etc.). It will handle 8 downstream channels. This model is a little more costly than an SB6180, since a router is included. If the router portion is not wanted/needed, it can be set up as a modem only. |
|
| Well I actually ordered the 6120 right after I posted last. It came in today (from Amazon), and I am not sure whether I should open it or return it and try to get a dpc3010.
How much better is 8x4 vs 4x4?
I'm really tempted to just open this thing up and see if it increases my speeds.
Does a standard D2 modem only connect to 1 channel?
Is the dpc3010 twice as fast as the 6120 (in theory)? |
|
| Sorry, I misspoke in my previous post.
My choice is between the Motorola 6120 and the 6580.
The 6120 has mostly positive reviews, whereas the 6580 has quite a few complaints. I won't be using the built in wireless functionality as I already have a more-than-capable router. Are the only problems with this one the wireless, or is it just a crappy device? |

Well 8 is twice as many as 4 so yes its better. Also yes a D2 modem can only lock onto a single channel either way. If your decision comes down to the 6120, and 6580. I would suggest just keeping the 6120, I will never recommend a modem/router. To many things can go wrong to be able to troubleshoot, and firmware updates and such are left up to the ISP to update. So your control over the router part of the modem will be limited. |

| Yes I know 8 channels is twice as many as 4 channels lol. I was just wondering if doubling the channels would necessarily double the speed. It is possible that I would notice no difference between 4 channels and 8 channels (if four channels are all that is needed to attain my top available speed).
Anyway, I went ahead and stuck with the motorola (it is actually a SB6121), and I am getting consistent speeds of around 20Mbps now. I am very happy.
I am also glad that I did not pay the extra $50 for the 8 channel modem as it seems as though my speed is limited to 20 (I have the Preferred package).
Thanks for all of the help, it is much appreciated.  |
