ge-1-36-ur01.polymer.tn.chatta.comcast.net - is the 3rd hop from my computer. The 2nd hop has 100% packet loss and I do not understand that.

The "ge-1-36-ur01.polymer.tn.chatta.comcast.net" had less than 25ms latency btw.

Now you have to figure out if the lowered speed coincide with other symptoms, such as packet loss to your first hop or consistently increased latency in the path during peak times. ]]> http://www.dslreports.com/forum/remark,20433435 Mon, 05 May 2008 09:19:26 EDT Re: Tech installed a New Line to house, now what?? http://www.dslreports.com/forum/remark,20433175 axelrose :

I was quoted $30.80 to run a line directly from the pole to my modem, no splits. Would you do this to see if it would fix it?

I notice on the tweak test your windows scaling is at 1.
have you set it to DEFAULT? (via DrTCP) it should allow it to scale higher.
you could also set your RWIN up to 200020 and see if that helps. also try again without the router. try 1 item at a time and then all combined
I wanted to keep 248840 as my rwin, anything else causes Tweak Test to say Rwin is out of range.

I've used DRTCP and cannot seem to change the Windows Scaling to anything but 1.

Is their a way to set scaling higher using regedit?
I think 248840 is >200020, but in your original post the tweak test said your RWIN was 128480 which I think is even less. Yes DrTCP is just a GUI interface to those TCP settings, so you could use regedit and maybe make it better, or maybe make it a lot worse. You should be setting it to ON in DrTCP, DEFAULT or OFF will limit you to 1.
everything else should be at default. If you set it to on and it still doesn't scale, then one of your dozens(hundreds?) of other tweaking attempts have messed something up.
I doubt i've had hundreds of problems, or course you're just joking around?

I already did the Rwin merry-go-round and settled on 128480, it's not a great choice but seems the best. It's basically like this...I'm choosing an old turd in place of a new polished turd of a connection.

Yeah, I'm upset but I'm getting more and more used to my 3meg connection while paying for a powerboosted 12meg connection...It's painful but what am I going to do about it?

thanks for trying to help me.

A Live Linux disk is a complete non-Windows operating system that can be downloaded as a single file, burned to a CD, and used to start the computer.

Here's a longer description of them:
»en.wikipedia.org/wiki/Live_CD
Here's a list of them:
»www.frozentech.com/content/livecd.php

I've used Knoppix, Puppy, and Ubuntu before for this sort of troubleshooting.

It completely bypasses any issues with the current operating system on your computer including anything that may be slowing it down, like a firewall, anti-virus software, TCP/IP settings, or any other OS settings.

If the connection is good with that, then it usually indicates an issue with the PC system, software, or settings.]]> http://www.dslreports.com/forum/remark,20428128 Sat, 03 May 2008 22:11:28 EDT Re: Tech installed a New Line to house, now what?? http://www.dslreports.com/forum/remark,20428085 axelrose :

If yes or you are 100% sure its not the problem it could be up the line from you. If possible, you could ask your neighbors to do a speed test and see what they are getting. If they are getting close to what you are, then the problem is up the line and Comcast is the only one that can fix it.

When I first had HSI installed it was AT&T. I was having exactly the same problem you are having. They had many techs out, Replaced all the RG6 and splitters, but could never get the problem fixed.
When Comcast took over I called them and told them the problem I was having.
They sent a tech out at 9AM, he looked at everything in my house and hookups and said the problem was somewhere else.
I didn't see the tech again until 4PM that day. He came back in, tested my speed and it was flying. When I asked what the problem was he said it was in the way I was being routed? I never asked him what he meant by that. All I know the problem was fixed and I have never had that problem again.
Maybe one of the Comcast techs on this forum could explain what the routing thing could be.

Hmmm... I can put a -3.5dB or a -7dB splitter in my line and see the exactly corresponding lowering of my DPL and raising of my UPL stats...

As long as my stats still remain in spec, I don't notice any difference in performance.

In the process of doing their jobs, they do introduce a definite and labeled amount of attenuation when inserted into the coax line.

Thanks. I believe the hole coming into this room is way too small to fit another cable through using your method.

But shouldn't bypassing the splitter inside my room give me the same result?

It most likely won't fix your issue but try going into your router and cloning the mac address of one of your desktops and see if a new ip block helps any. (and if one doesn't work, try another desktop). Just make sure you reboot your cable modem each time you do this.

About 25% of the time it did for me. I don't know why, but worth a shot. You could always hook up the modem directly to the computer too. But, i have not been paying any attention to your issue. You might have tried that already.

Just shouting ideas.

range. Tech did agree that my line speed was slower than most people on my tier, he agreed it was probably

an issue beyond my house, perhaps nod/router equipment owned by comcast?

The tech also tested my signal directly from the pole's line and they were good. He also tested my signal with

the 2-way splitter I have inside the house and test the signal as it went through the router, and all signals

were good he said. I asked if a new 2-way splitter would help and he said no, not based on the signal he

was reading. I also asked about a new router and again he said no it wouldn't help based on my signal

readings.

I have a 5-10% decrease in lag but in exchange I now have a 1.5meg decrease in average speeds.
