Am I reading that wrong or does it say the cap on your upstream is 10.24mb?

said by Tech58 :

If you live in the phx area channel bonding wont be avalible for some time when it does open up you should see around 300-500 mbs. If you have a docsis 3 and you are having problems with it, its most likely trying to channel bond and causing the tap or node to have problems because you are sucking the signal away from everyone else. But thats just what ive seen since it came out and ive been installing them

said by kansei :

Is 28Mbps/5Mbps possible on Cox's network without channel bonding?

said by kansei :

Is 28Mbps/5Mbps possible on Cox's network without channel bonding? If so, then I could care less about the bonding. It was maxing out at roughly the same speeds I got with the old modem and the lower Premier tier, which made me think the channel bonding is what I was missing.

The tech even said he installed Premier Plus for someone a couple buildings down from me (i.e. inside the same tiny gated condo/townhouse community) and the speeds were good there.

As a plus, I know all my cabling is in impeccable shape.

...Hey, wait. I get to make that call.

said by CoxTOC1 :

Check again :)

stevieg2123, if you are still seeing issues you might want to call in. I noticed that your modem is doing quite a few power adjustments and your Tx is a bit higher than I like to see it.

said by threegsus :

Hey TOC1,
Remembering all the help you gave me in the past, I feel a tad conflicted offering any suggestions, but you're one of the few Right Coasters (especially DC-ites) that thinks life west of the Mississippi is civilized and worthy of concern. Basically, we suck hind tit and you guys get the good stuff first. You can clearly see I don't have upgraded firmware either so it's looking more like a plot than an accident...or maybe local mgmt is a tad slow on the draw.
Regards

said by CoxTOC1 :

I have it on good authority that the firmware testing is well underway and that we should be seeing it soon. We just want to make sure that it does not cause other problems within our system before we roll it out.

said by kansei :

So what did he do? He took the DOCSIS3 modem and left, no resolution at all, just said "well that's too bad".

Those all appear to be from the same server. Anyone thought of the possibility that no one guarantees the accuracy, bandwidth, or utilization of these speed test sites

said by dogblue42 :

These were done within seconds of each other to two different servers on speedtest.net. 21M DIFFERENCE!!! I would say not all servers are created equal.

I see a bunch of tests from brian2220 that are 17M, 22M, 25M, 27M, 30M. Not really sure I understand what the problem is.

I'm bonded to Channel ID 1 @ 579000000 Hz and 51 @ 5730000000 Hz.

said by CoxTOC1 :

I hate to point this out to you but, according to your bonded screen shot one of the channels that you have bonded to is channel 0. Which as far as I know does not actually exists.

What you were seeing is most likely a "phantom" channel. The modem thought that it was bonded to a second channel but in reality it really was only bonded to a single channel.

said by rainabba :

BTW, the LINK light on my 6120 is blue because I'm connected to a gigabit interface so just seeing blue doesn't mean you're bonding.

At the least you'd have to confirm the blue is on the up or downstream lights.

When looking at »192.168.100.1/cmSignal.htm , how exactly do you know if the modem IS bonding?

said by CoxCommNeedH :

Cox really needs to do something for my service, because lately last few years it really blows. Charging us $59.99 a month for the Premier and give us budget performance.

said by CoxCommNeedH :

What can be done to get this up to the numbers you guys are showing?

said by ajwees41 :

Moto SB6120 is Docsis 3, so it could be bonded.

said by brian2220 :

my phoenix speedtest sucks

said by Teebeebee :

I just got those readings so that is significantly higher than anything i've ever gotten, i think it's bonded

said by Nerdtalker :

Actually it will bond if you're in the right market/plant; you'll just get the slower speeds. That's what I've been told, and it makes sense provisioning-wise.

said by Nerdtalker :

So has anybody successfully used a DOCSIS 3.0 modem on a non Premier Plus tier? If so, has anybody seen improved speed stability?

(By that, I mean getting consistently fast advertised speeds even during the times when normally congestion lowers the real downstream speed?)

said by Nerdtalker :

Look at the frequency for the downstream channel, and the downstream channel ID

said by dvd536 :

Yeah they need to offer more on the upload side than a lousy 512kbps for $20 more. how many sites does one get even 10mbps download on.
oh yeah, the setup fee would have to go too.

said by Nerdtalker :

So this is essentially a $20/mo upgrade for customers on Premier, without channel bonding, that essentially provides only marginally faster speeds? What good is DOCSIS 3.0 without bonding at least 3 downstream channels and increasing upstream speeds as well?

I think I'll pass. I'm willing to pay just about anything for faster internet, but it just doesn't seem like enough of a change to merit even the headache of getting a new modem, calling Cox, e.t.c. unless they offer at least 35+ megabits/s.

Interesting notion being on a different downstream channel dedicated entirely to DOCSIS 3.0 customers, but I have to wonder whether they'll see faster or slower speeds since everyone there is a bandwidth-hungry power user.

said by DAVPX :

I'm happy getting 10 Mbps over what my plan advertises. I just feel sorry for those paying $20 more and getting 1/3 of what I get.

said by madden2k5 :

Whats your complaining about anyways? you act as if your gunna be maxing out 160mbps all the time, and im pretty damn sure thats not correct. As for your statement above, thats not a minimum at this time, for the simple fact your only gunna hit 160 if you have 4 channels maxed out. There isnt even a 8channel d3 modem on the market thats retail.

said by madden2k5 :

LOL at you because atm all cable op's are only using 4 channels down, and that 160mbps is the max for 4 channels, so until they start using like 8 channels there is no way in hell thats a minimum, are you crazy? Please don't always believe what you read or see on the internet.

said by rainabba :

With the D3 modem I'm on 573MHz and have SNR around 37db, downstream power level of -1 dBmV, and upstream power level of 43 dBmV.

said by dnaegele :

Hi.

Qwest charges $79.99 for 20mb service on a month-to-month basis. Or $69.99 for 12 mos. if you sign a contract.

Seems like Cox is a better deal PLUS if you bundle you get more savings. I'm already saving $33 a month with bundling and 20mb service.

Don

said by rainabba :

The cox tech just left and I'm now running Premier Plus with the 6120.

According to testmy.net, my download has hardly changed, and is still lower than I've seen it here in the past, and much lower than I've seen it a month ago at my previous residence in Ahwatukee.

My Upload has improved from 2.3Mb to 3.7Mb (on this last test) though and that strikes me as nice, though that's not the 6MB test because despite the links existence, testmy.net says there is no such test. That said, there may still be some PowerBoost corruption there.

I don't have the blue light yet. Anything I can/should do here ,like call customer service and complain that I'm not getting ANYTHING like the 25Mb I should be getting?

Also, via the Motorola web interface, is there any way to tell if the modem is using bonding?

Also, for those who keep going on about the D3 modem being overkill.... Yes, for another month of so, then you might not feel that way. I've heard from a couple reliable sources over the last couple days, that the speeds being announced now are effectively "introductory" values and we should not be surprised if someone "opens the spicket" very soon. ;)

said by mryanbrown :

As a horrible example let's say the powerlevel at 579mhz is 45dbmv, and 585mhz is 47dbmv. That means you can't use anything below 579mhz or above 485mhz or you would be beyond 2dbmv difference.

said by tubbynet :

ummm...dbmv is a measurement of powerlevel, not of frequency :uhh:

said by mryanbrown :

Oh but according to Cox your carries have to be within 2dbmv of one another, so you can't hop to the other end of the usable spectrum where bandwidth may be available.

said by tubbynet :

unless, of course, you are on a different downstream carrier

again, the congestion detection mechanisms in d3 will allow for dynamic channel hopping and pushing data across different channels. the congestion still occurs on that given frequency, but you won't feel it because of the multiple channels.

said by mryanbrown :

It's the same with DOCSIS 3. It uses the same modulation? What's the difference? It's essentially 2 standard modems on the node, in 1 piece of equipment.

Any data reliability issues present in D2 will be almost identical on D3.

If a node has ~10Mbps/free because it's congested then whether or not you have D2 or D3 doing 28Mbps, you won't get it.

said by madden2k5 :

Well cox is point is... with more channels bonded, it will cause less slowdowns with everyone's speeds. So cox is making everyone switch to D3 for any speed tier above there already 20/2 or 20/3 tier.

said by tubbynet :

reliability from a consistency of speeds standpoint. sure, d2 can offer those speeds, but that is on a crystal clear node with *no one else using it*. the issue becomes that as you add users, you tend to lose available bandwidth because other people are taking it. this is the whole reason why powerboost works on some nodes, and not on others. its a matter of congestion. if you take a gander into the optimum online forums, you can see boost users complaining about not reaching the speeds they are paying for. its because *other users* are *also* trying to get the speeds they pay for.

q.

said by mryanbrown :

Are you serious about the D2 maxing out at 38mbps so 28mbps would be unreliable?

said by fuzzyfuk :

What modem do you guys recommend? The Cisco or Motorola? Thanks.

said by lk182 :

so apparently the node outside has not been upgraded yet to d3
They are leaving me with the cisco modem and the premiere plus plan but I have to call in for a 20 credit to my account.
this sucks.

said by ryscar :

I agree that they make good modems... that is the only kind I have ever had. I just figured that if the modem fails for what ever reason within that year, I just call up Cox and they take care of it.

I would have probably bought the Motorola if I could have got them to wave the install fee but, that was a no go with the DOCSIS 3 install.

Either way, they do the same thing so all is good.

Just a little info that the tech told me when he installed my modem:
If you buy the modem from Cox, they will warranty it for a year. I don't think that you can get that from Frys or Best Buy.

I would rather have a Motorola modem because you could reset it via the web interface but, I figured I probably shouldn't pass up the year warranty living here in AZ and having to deal with the monsoons.

28 megs doesn't require a D3 modem.

I just called cox to upgrade from premiere to premiere plus and the agent said i didnt need a new d3 modem or professional install.
i'm confused cause i have an old webstar modem...did the agent fubar my order?

said by meecrob :

Unfair? speed tests are pointless when using a Cox connection. I would have posted results from the Scottsdale server with the Cisco modem, however, at this time I am not able to run a test from the Scottsdale server. When I try it returns an error saying that there was a problem with the download file. I think that may be an issue with that specific server as that server has been disappearing and reappearing on the speedtest.net website. Sure I could use the server in Phoenix, but that server sucks and always returns speeds much lower than any other nearby server.

Most people only post their results from speed tests and believe that those results are the real speeds they are getting. I for one am really annoyed by those people and as much as others try to explain power boost to them, they still don't get it. I posted results from both modems and plans to help others realize that users on Cox and Comcast need to perform tests that last after power boost is gone to see what they are really getting. Power boost is a nice way of confusing customers into believing they are getting better service when in all actuality they are not, and often times may not be what they are paying for or expecting.

I have multiple devices and services on my network to monitor my actual throughput speed. When downloading and uploading information I do see that nice power boost which shows me downloading at around 32 mbps and uploading at 3 mbps, but about 5 seconds later it slows down to the actual speeds I posted for both plans. When it slows down it levels off at the speed I posted which are also the speeds posted on the Cox website.

So far most of the posts by other users on this topic are of no use to people who actually understand throughput and want a good review of this new service.

said by DrThodt_ :

I wonder how quickly markets such as AZ which always seems to be near last amidst the upgrade train will find use of it's 1GHz E.O.N system seeing as it would require entirely new set-tops and we get shafted on simple things such as DOCSIS 3.

Maybe they will just upgrade the SA firmware to Tru2Way to meet the requirements of capable set-tops versus just buying new ones.

said by SDKiwi :

Existing 1.x and 2.0 modems and existing MPEG-2 STBs can not tune above 860 mhz. Those will be around for many years, but they will not all have to be replaced to offer services above 860 mhz.

said by tubbynet :

not until the new round of stb's are deployed market wide can this happen. at this point, nothing in any cox market exceeds 860mhz (as that was the majority of the previous plant gear). even the tuners in the stb's and in the cable modems doesn't exceed this mark. to redo the video frequencies would require a massive rollout of new cable boxen.

q.

said by EvelKub :

I would not see it entirely switching to a different frequency, but they can up the number of channels dedicated to HSD with the ghz system they've upgraded to. Video can move on up and data (including voice) can occupy more of the lower channels.

said by meecrob :

Also after speaking with the sub-contractor apparently the only real reason they come to install the modem is to verify that your SNR is above 36 db.

said by CoxTOC1 :

Now to a issue that we have discovered for those adding a SB6120 to their account. The default firmware out of the box has a issue that causes the modem to lock up every couple of hours. The latest firmware will fix that though. What I would recommend doing is once you have it hooked up go into the status pages at »192.168.100.1 and find the button to reset you modem. If you click on that link it should trigger the firmware download. The latest firmware that we have is SW_REV: SB6120-1.0.1.7-SCM00-NOSH if you reset it and don't see it show up within a hour or two PM either myself of CoxTECH1 with your MAC address and we can push it out to you.

said by DrThodt_ :

Oh so back to my initial arguement that there should be a 2dbmv difference between channels already present?

said by DrThodt_ :

imo its a complete ripoff regardless until it passes 38mbps.

Can anyone @ Cox offer anything in regards to a fee for installation? The website says no, Cox says yes. Just confusing. Possibly unethical.

said by DrThodt_ :

I'd almost hope they weren't channel bonding. Yay added overhead using multiple channels when you could just use 1.

said by AZHSISupport :

Regarding my previous post, this is only specific to the AZ market and I would contact your local market for questions regarding area specifics. The Motorola SB6120 is on the approved Cox modem list for all markets.

Thanks!

Q. What DOCSIS 3.0 modems does Cox support?
A. Currently, the Cisco DPC 3000 and the Motorola SB 6120 are approved for use on the Cox network. Customers can purchase the Cisco model directly from Cox for $99.99 or a Motorola 6120 at a retail outlet.

The Motorola CB 6120 is approved and will work with all tiers of CHSI including Premier Plus.

Let me know if you have any more questions and I’d be happy to help!

Please remember I can only tell you what is going on right now based on the information that has been given to us. And unfortunately sometimes I am the last to know about something. Like I have been saying right now all the documentation that has been given to us is that the DCP3000 is the only modem authorized for the DOCSIS 3.0 tiers of service. That could change in the future (and more than likely will) but when that will happen I do not know. All I am advising is that you be careful in your purchases and contact your local system and see if they will let you use it for the DOCSIS 3.0 tiers. I would rely hate to see a bunch of upset customers who bought a SB6120 only to be told later that they can't use it.

said by thundar :

I spoke to a Cox Tech manager and the SB6120 3.0 speeds are supported here in AZ, it was in thier powerpoint info from manager meeting about the new Plus service. So I just have to wait the 3 days for network guys to check the node and such and should be on the Premier Plus package. I post my impressions once I'm up and running.

-Big thanks to Matt for your help if you read this!

My SB6120 is not on the Plus package yet, but getting this on the old Premier package (on the 6120)... So should get some good speeds once its on the Plus:

said by ajwees41 :why are the motorola's on the approved list then when Cox will only install the DCP3000 for Docsis 3.0 tiers?

said by CoxTOC1 :

If all you want to do is add the SB6120 to your account their will not be any additional fees. However if you want to get the Premier Plus tier then you will have to pay the install fees (You may also need to buy a DCP3000 as all of our information states that is the only modem that we will install for the DOCSIS 3 service tiers).

So if I goto Fry's and buy the SB6120, and then call cox and say I want to provision my new modem and add the Plus to my Premier account are they going to try to charge me @29.99 install fee? I already called ealier and they said was available in my area so hope that is ture.

said by thundar :

I just saw this today also, $20 more for an additional 5mbit down and .5mbit upload is kinda high... But my biggest question why do you need Docsis 3.0 modem for these speeds? I can only hope this is just a temp package and soon will offer real Docsis 3.0 speeds for this price (hench the need for Docsis 3.0 modem.)

said by BillRoland :

I have to agree, that package is extremely weak for a DOCSIS 3 product. Heck I've seen those speeds (obviously they were monkeying around with something) on DOCSIS 1.1 here.

said by Ikyuao :

Mmmm That should have large window size of TCP header can really archiving much faster throughout than small default 64KB TCP window size that you can do nothing about trying to tell cox to reduce latency so having large window size of TCP header will do you a good of getting a big throughout. DOCSIS series won't do whole TCP header offload for you.

said by madden2k5 :

if that package is $79 that very weak, and i wouldnt order that package nor support it, with still only have max 2.5mb upload with powerboost. Hell here are 20mb down package comes with up to 3mb upload here. but i only see close to 2mb up.
