Re: [Business] [POLL] Do you have the new 15/3 or 27/7 business said by NetFixer:While the ratio of real techs to script readers is better with business class, it's still the luck of the draw when you call for support.
There was a noticeable drop in quality of rep when they centralized business support. The local Minneapolis support team was awesome, back when they existed. |

I believe I misunderstood the person about the Netgear they mentioned.
It sounds like it could be a new device I guess? It wouldn't make sense for them to offer the Netgear 8013/8014, since neither of them is DOCSIS 3 capable and I doubt they could do 27/7 reliably.

| Netgear does have a commercial grade DOCSIS 3 cable gateway box:
»www.netgear.com/service-provider···CR.aspx#
Not much information on the Netgear web site since it is apparently only sold to service providers, so Netgear doesn't feel that there is a need for potential end users to know very much about it.

True, but there are no Netgear modems or gateways on the business class approved modems list, and apparently someone from Comcast has proposed using a Netgear box to solve the problem being seen by pflog.
It is possible that this Netgear box may be under testing and consideration as a replacement for the SMCD3G-CCR which is apparently not being very cooperative in working with Comcast's native IPv4/IPv6 dual stack.

Yep, I had to refresh my browser's cache to get it to show up in the main business class list, but it is now on the approved list. Strange that it does not yet appear to support IPv6; I would have thought that would have been a high priority requirement for a new device on the approved list.

Thanks for the correction. I will assume that they then have a configuration file for it so that it functions on their system ? |

I rebooted the SMCD3G at our shop today and we have the new speed!:

Looks like it's 17/3 for us! Also one thing I noticed is that the Powerboost is no longer unthrottled, before i was getting up to 50 MBps upload with PB |

said by NetFixer:said by WheatridgeCO :SMC D3G Hardware Version 1.01 / Firmware Version 1.4.0.49.7-CCR / Running in Bridged mode with 5 Static IP's thru a Cisco Pix 525
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. He means "true static" mode - that's normal with static IPs - its the same config I use with my static IPs

said by NetFixer:said by pflog:He then went on to ask me what the problem was, and he said something like "the DNS server is not set, I will enable that and it will fix your problem". 
I've gotten that same advice too, and also have been told that the SMC gateway will not even work unless you enable its DHCP server, and that the SMC gateway's 1-1 NAT was the only way you could use your static IP addresses. said by pflog:Naturally, it didn't fix the problem. Then he asks where I'm testing from and I tell him various mirrors and he tells me "engineering requires you to test from speedtest.comcast.net to get an accurate speed result". SIGH, and I was just talking about how the business class support reps were more knowledgeable.
While the ratio of real techs to script readers is better with business class, it's still the luck of the draw when you call for support. that's not even remotely correct - you can use true static mode with static IPs. Your static IP is routed thru the modem. It's a standard config

| said by JohnInSJ:that's not even remotely correct - you can use true static mode with static IPs. Your static IP is routed thru the modem. It's a standard config This is TRUE for STATIC IPs, EVERYBODY, all you need to do is set Disable Firewall for True Static IP Subnet Only / Disable Gateway Smart Packet Detection on the firewall page, and then
use YOUR OWN ROUTER, and Do not use DHCP to get IP address from the SMCD3G, put in the REAL STATIC IP address in YOUR ROUTER, and the SMC will pass all traffic straight thru. (This way your only NAT'd once, as long as you set that up inside YOUR OWN ROUTER. Not that hard to setup traffic rules inside Cisco routers, and almost any security appliance with NAT cabability will work well. We let windows assign DHCP addresses on the LAN side, the Cisco/Security appliance only needs to know what the
address range is. We do not let the Cisco/Security appliance divy out DHCP addresses, even though it can. In a Windows-Server enterprise its better to let it keep track of DNS/DHCP that way it keystones everything and integrates better with Active Directory.
Another thing I do at our office is this :
I connected a cheapy Netgear wireless router directly to one of the 4 ports on the SMCD3G, and I set it up to get a DHCP address from the SMCD3G 10.1.10.X address and I let guests that visit our office use the netgear for internet access, and that keeps them off of the LAN side of our Cisco PIX thus securely on the otherside, just like any other internet user would be. This also makes a nice way to test Cisco VPN Tunnelling software inside our office, thru the Cisco firewall.
There is one more great benifit of setting this type of IPV4 setup, if you ever change providers, then you will only need to make minimal changes IN YOUR OWN ROUTER. all internal IP's would never change, thus no more changing the entire enterprise's IP addresses, as you would keep the NAT'd IPs that you setup in your OWN ROUTER. Change your domain records, update your DNS records, change the static IP in YOUR OWN ROUTER. and the whole change to a new provider would be done quickly. |

SMC D3G
Old: 12/2
Apparently new: 15/3
This past summer, my speed tests were looking like this:
I call BS on the accuracy of the results since my real world usage of downloads and uploads supported the bottom tier I'm on with PB being quite high. When I first signed up, my speed tests had PB pegged usually around 75/40. I don't have a shaperprobe log for this time period though.
Now my speed tests are more like this:
Based on real world usage and speed test this is relatively accurate and my PB has definitely been lowered, especially the upload, like others have reported.
Here is the shaperprobe I took today:
DiffProbe release. January 2012. Build 1008.
Shaper Detection Module.
Connected to server 38.107.216.34.
Estimating capacity:
Upstream: 4012 Kbps.
Downstream: 21497 Kbps.
The measurement will take upto 2.5 minutes. Please wait.
Checking for traffic shapers:
Upstream: Burst size: 4939-4968 KB;
Shaping rate: 3192 Kbps.
Downstream: Burst size: 9765-10006 KB;
Shaping rate: 17061 Kbps.
This is really a bummer given the higher cost and no promo offers for business lines. Personally I'm only paying the premium for no caps, 1being inline with the TOS, and better support. Based on the service I've been getting all around, I'm not sure it's worth the premium. The last problem I called about, it took them half a week to send a tech out. |

OK I seem to have my packet loss issues worked out (there were like 4 contributing factors) and got my SB6121 provisioned.
- location
St Paul, MN
- what modem do you have
SB6121
- original speed plan
12/2
- new speed plan
No notifications, but it looks like 15-16/3

- do you see power boost? if so, is it more or less than before?
Powerboost is weird; I get inconsistent reported down (anywhere from 11-25) but ridiculous up.
»stage.results.speedtest.comcast.···4372.png
- do your speeds remain consistent after powerboost? or are they erratic as in the link
Seems stable at 2.0MB/s after boost on a 1.5GB test download.

Update: Techs reworked my line today because it was pretty old and grounded to a water pipe. Speedtests look normal now:

Did Comcast completely kill PowerBoost on the upload?
Ever since Comcast's support reset my modem, I'm not getting upload speeds any greater than my plan.
Here's what I have from my last test:
This is a test from before the new tiers. It's the most recent I was able to find.
It's pretty pathetic that Comcast had no problem rolling out new, much faster tiers for a wide variety of residential modems, yet they can't even get their config correct on a whopping three modems for business customers. |
