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

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...

Yes I signed up with my own modem as I have heard nothing but nightmares about the SMC devices and do not need static IP addresses.

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.

m00ster See Profile do you have a way to see the config/boot file on your modem? Or even better, the config values?

I was given mine (I can't actually see them myself on the SMC):

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.)

He means "true static" mode - that's normal with static IPs - its the same config I use with my static IPs
