[Business] [POLL] Do you have the new 15/3 or 27/7 business spee

It seems there are quite a few people noticing the new business class speed tiers:

- 12/2 => 15/3
- 22/5 => 27/7

Can you all post:

- location
- what modem do you have
- original speed plan
- new speed plan
- shaperprobe results
- do you see power boost? if so, is it more or less than before?
- do your speeds remain consistent after powerboost? or are they erratic as in the link

I'm curious to see if it's rolled out to all areas or if it's specific test markets at this time. Also curious if I (and I think espaeth See Profile) are the only ones on 27/7 seeing erratic speeds after powerboost and if ropeguru See Profile is the only one without powerboost now after the upgrade to 27/7.

Thanks everyone!

Interesting, good to know it's working in some places. Interesting, too, that you have upstream power boost and the same fast downstream power boost. hmm. When did you last reboot your router?

I'm REALLY starting to think the SMC D3G is at least part of the problem.

I don't know enough about HFC networks, but is it possible the SMC D3G config file is just hosed and other modems' are not? I don't know why it would take this long to figure out if that's the case...

Gotcha. Well, from this thread and the other older one that was California specific (or started that way), so far it seems like:

- 15/3 on non-SMC modems: OK
- 15/3 on SMC modems: OK
- 27/7 on non-SMC modems: OK
- 27/7 on SMC: problems

I'm hoping more folks chime in here and the above pattern solidifies itself.

Comcast Speedtest results with local rate limiting


FWIW, I have not experienced the sawtooth downstream speed symptom. When the remote host is capable, I see a fairly steady 15-16 mbps traffic stream after the initial PowerBoost burst.

Out of curiosity, how are you determining the speeds are consistent after PB?

In my case, they DO average out to 27 Mbps, so the overall average speed isn't the problem. But if you look at the traffic second by second (or in even smaller time intervals), it looks like a sawtooth pattern as I posted in the other thread.

I'm not going to concern myself with a microanalysis of the speed consistency. Note that there was some PB in this transfer, though it doesn't ever show up in shaperprobe and most of my downloads don't let me go fast enough to notice it. The download holds around 3.4 MBps.

Fair enough, you may not care, but it IS broken for me and I do care, and it should be fixed.

I was just trying to see if your profile is actually working and was hoping you could help out to see if your speeds are consistent or not. But I understand that if you don't care and it offers you no benefit why you don't want to, no worries.

FWIW, the windows task manager aggregates the speeds I think, so it wouldn't show up there. Something like netmeter/dumeter or wireshark and the IO graph would, but I don't think the task manager graph will.

I still haven't seen a 27/7 profile that doesn't have the /\/\/\/\ pattern after PB.

I am doing a 4GB download from Georgia tech right now. I have NetMeter running and watching the download speed it is all over the place. Not even a V pattern like you are seeing.

It bounces randomly something like 28,24,16,33,35,16,18,28,etc.. Even dying a times for second or two. Even the download spped showing on Firefox's downloads window is all over the place.

See attached graph for how bad it is... Cannot even tell if powerboost is even there or not.

Yes, that's what I'm seeing as well. The sawtooth pattern is sort of there when you look at it over a higher time interval or the speeds are averaged/smoothed.

So yeah, sounds like you and I are seeing the same behavior after the PB ends.

Unfortunately, I'm also seeing a reduced Powerboost. I'm on the 12/2 tier, and I used to get boosted speeds (on speed tests) around 80Mbps/40Mbps. Now, the boosted speeds are 21 EXACTLY and 3 EXACTLY, returning to 12/2 after the boost is done. I've called a few times and emailed the Comcast Cares department, but no one can figure out why I've lost my boosted speeds.

Looks like you're seeing the same thing as me. Can you confirm whether or not you're seeing erratic speed or if they're consistent after power boost?

Is this just a simple miscommunication between the people writing/pushing the configs for SMCs vs. non-SMCs?

Wish Comcast would address this. It's been a month now.

Is this a new connection? I was not aware that Comcast allowed that configuration. I was told that you had to use an SMC gateway in gateway mode in order to get static IP addresses.

Or are you confusing not using the SMC's NAT with bridge mode. Unfortunately, that is something that a lot of uneducated (and/or unethical) Comcast CSRs seem to do, and their referring to doing that as bridge mode in turn confuses a lot of customers.

I think PB is tied into how congested your node/head end is though. If your on a more congested node you may get less PB as i was under the impression that PB used free capacity at the head end.

I happen to live in a fairly rural area, so I think my head end isn't too packed.

Prior to this speed upgrade, I was seeing 70+ Mbps downstream powerboost and like 30+ upstream powerboost. I don't think my node is congested at all.

Well the operating mode says RG, which is gateway, but I am not using the Nat'ed addresses. Its local DHCP says 10.1.10.1 and thats the address I used to get into the web interface, but I use our real IP addresses on the PIX, and they pass thru all traffic, I did see that Disable Firewall for True Static IP Subnet Only &
Disable Gateway Smart Packet Detection have check marks. Strange thing , we actually can use all six ip addresses! (with a wireless router attached to one of the ports directly, not on the otherside of the PIX, I get the .30 address. .25 thru .29 pass to the pix just fine. I have the pix configured static and use a windows box for our lan side DHCP configs. Works like a champ.
Is this why peeps are complaining about the gateway mode, are they using some cheeseball router and not setting up the real IP addresses using static configs. Never use DHCP to get an IP address from a SMCD3G, just put in the real ip address into the router. and then Nat your network. Much simpler way to change the WAN side configs without ever changing the LAN side. (I guess they dont want to use a REAL router that actually protects your network.)

Well I'm being told I have the following options:

- drop my static IP addresses and get a residential modem
- use an ancient Netgear device that doesn't even do DOCSIS 3.0
- "deal with it"

None of these are acceptable options in my opinion.

Can someone who works with these devices PLEASE explain why:

- the SMC D3G can handle a 22/5 profile and powerboost of 60+ Mbps down and 30+ Mbps up
- but can NOT handle 27/7 properly

This makes no sense. I wish my contact in business escalations was still in that department.
