[Speed] "Upgraded" to DOCSIS 3.0, speed halved.

I had an ancient SB5100 and all was well. My mom was renting a modem so I thought I would give her my SB5100 and I would upgraded to a SB6141.

Well I just did. Before the upgrade I was getting

DN: 21Mb
UP: 2Mb

Now I am getting

DN: 8 - 16Mb
UP: 2Mb

The tests were done an hour apart after the new modem was up and running. Is this normal? Does it take time to come up to speed? I have the performance tier so I'm good with the speeds. I just expected an increase or at worst the same, but not a speed drop.

Can you run shaperprobe and post the results?

Did you have the new modem provisioned correctly ?

How exactly is the end user to know that ?

Call and find out if it was done correctly... Like anyone else.

That would seem to be a reasonable first step.

I will call them. It took him several tries to get it going so he might have just 'tried something' in the end.

Wouldn't hurt to call and have them re-provision the modem, but it really would be good to see shaperprobe results as I asked.

Can every single one of their phone reps really be trusted ? Come on, you've been around long enough to know the answer....

Then post in the Direct forum. Bottom line is HE has to contact someone with Comcast, we can't do it for him and we cannot tell him if his config file is correct.

Generally Agreed. I've had very good results by relying on the Shaperprobe tool to advise posters of their provisioned speeds.

I agree with both steps.

First, try to re-run Shaperprobe and let's see what's what, as well as also posting the SB6141's status page...should give some idea what is going on. Then if need be a call to Comcast CS may be called for. At least that way, the OP can be on a little better footing explaining the issue, yes?

Were I in a similar situation, that is exactly what I would do: Perform as much diagnositc/trouble shooting 101 stuff on my own as possible, only then calling CS. That includes the simple things like double-checking connection, re-booting the modem, and if going through a router, ethernet-connect the modem direct to a computer first to make sure that this is on the modem end of the equation.

That almost always helps me get quicker, better results when dealing with CS.

Why not ? Simply go to »192.168.100.1/cmSignal.htm

Plug your PC directly into the cable modem, statically assign an IP of 192.168.100.2 and a netmask of 255.255.255.0

Then try it...

I have 2 switches, 2 wifi AP, and a router, phone TA, printer, etc. All giving up their web access pages just fine. This one is not.

Remember, I had a SB5100 plugged in before this one and it uses the same 192.168.100.1 address.

This is a no go.

You have something configured wrong then.

So connect a PC directly. If it doesn't work then you know it's the modem. If it does work, you know it's something in your network setup/configuration/layout.
