Re: Getting Comcast, need some help

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

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

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?

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'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).
Thanks…

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?

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.

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 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.

Glad to hear your internet service is treating you well.

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).

Here's the speeds I'm getting in a middle of a 5GB download:


This is what my modem stats say:


I also did a few tests, I hope these a okay results:

16/2

At least that's what I'm signed/paying for.

I may be over 250GB maybe 3-4 times.
That should be fine, but as you can see by the AUP, they can decide at will what is 'too much', not unlike the residential side.

I got a Motorola SB6120 modem installed.

I don't have DOSCIS 3.0 service, but it's working nonetheless.

It says I have 2 QAM256 bonded channels, 36 dB SNR, and 7 dBmV for for download. [3] QAM16 channels and 37 dBmV for power for upload. Are these values good?

Also DHCP is on, but there is option to turn it off; how do I turn it off? I already have a router.

I'm interested if you get flagged with multiple TB/mo, so do let us know!
Like I said, I probably won't be download multiple TBs of data, but I may be over 250GB maybe 3-4 times.

Did you *read* the service agreement you signed?

It's right there.

»business.comcast.com/terms-condi···dex.aspx

Specifically in the AUP
»www.comcast.com/Corporate/shop/b···use.html
quote:
Are there restrictions on data consumption that apply to the Service?
The Service is for commercial use only in a small, medium, or large business as determined by the applicable Business Services Agreement. Therefore, Comcast reserves the right to suspend or terminate Service accounts where data consumption is not characteristic of a typical commercial user of the Service as determined by the company in its sole discretion, or where it exceeds published data consumption limitations. Common activities that may cause excessive data consumption in violation of this Policy include, but are not limited to, numerous or continuous bulk transfers of files and other high capacity traffic using (i) file transfer protocol (“FTP”), (ii) peer-to-peer applications, and (iii) newsgroups. Your business must also ensure that its use of the Service does not restrict, inhibit, interfere with, or degrade any other person’s use of the Service, nor represent (as determined by Comcast in its sole discretion) an overly large burden on the network. In addition, your business must ensure that its use of the Service does not limit or interfere with Comcast’s ability to deliver and monitor the Service or any part of its network.

If your business uses the Service in violation of the restrictions referenced above, that is a violation of this Policy. In these cases, Comcast may, in its sole discretion, suspend or terminate your business’ Service account or request that it subscribe to a different version of the Service if it wishes to continue to use the Service at higher data consumption levels. Comcast may also provide versions of the Service with different speed and data consumption limitations, among other characteristics, subject to applicable Business Services Agreements. Comcast’s determination of the data consumption for Service accounts is final.

I assure you, it is not "unlimited" - it seems to be fine, but there is sufficient wiggle room to the agreement you signed to kick you should they decide they want to.

The rep I spoke with said "no caps" too. It's a common misconception. I'm interested if you get flagged with multiple TB/mo, so do let us know!

I understand anyone can get business class service. If there is indeed a soft cap then the lady who set my account up lied through her teeth.

As with getting flagged for a higher tier... I wouldn't mind getting a faster tier, since I'm already on the fastest one they offer. If they give me a faster one I'll take it.

I can live with a 1.5TB cap though.

I read through most of the threads/FAQs, but still have a few questions:

I will be moving [temporarily] to an area where they offer only Comcast. I'm looking to either get the Ultra or Extreme; however I have read the speeds are based on "PowerBoost" which I have not a clear idea to what that is,

it's a way to trick you into thinking you have a faster speed then your paying for

and to inflate Overall On speedtests

I believe I have read here that the soft cap for business is .75TB for 12/2, 1.5TB for 22/5, and "a lot" for 50/10

I'm on 12/2 business class, and run between 180-260GB/mo

According to the AUP I signed, they can decided I am using more then average for businesses in my tier and offer me to either move to a higher tier or terminate.

Anyone can get business class - just call the business order line and see if you can get it at your home address. You can be a home business, self-employed, a teleworker, whatever.

I needed the 5 static IPs, so that's why I'm a business class account.

I can tell you there is NO way you will be able to run 1TB or more a month through a residential account without tripping the "too much" flag.

Hi guys…

Wanted to post an update. I had Comcast service set up on Friday afternoon. A friendly tech came on time. He called 15 minutes, 5 minutes, and when he arrived. Very courteous—entirely not what I expected. He was quick and the set up was 5 minutes. Apparently for commercial class service they don't do any configuration; it's just plug and play.

After he left I realized the internet didn't connect. My fault for not testing it. I called CS and they sent another tech after about 30 minutes who swapped out the modem they gave me and everything worked. I will replaced the modem they gave me later. The first modem was an RCA-branded modem and when the second technician came I asked if I could get a Motorola Surfboard instead; again it was a swift "sure I can check" and next thing we know, I've got a Surfboard set up.

Now as with speeds, I downloaded a bunch of files about 500MB each and I averaged about 2.5MB/s, so if we assume 8 bits per byte, that's more than the 16Mbps that I've been guaranteed which makes this more than spectacular.

That said, I am entirely satisfied with Comcast at the moment; all those horror stories seem less than justified. I hope to have a good experience with them.

Anyways, thanks to everyone for answering my questions from before.

I guess it is always good to have a spare, so why not keep it if it is free.
