|  Tech installed a New Line to house, now what??
Tech installed a new line from the pole to my house. Tech also installed new 3-way splitters outside the
house. Tech also called in to check the modem numbers were in range and they/he said they were in normal
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.
Any comments would be welcomed.
thank you.

The one thing i noticed when i had comcast was if i started to have slow speeds or my pings got out of control, getting a new ip address sometimes fixed it. 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.

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 |

Is there a possibility of getting the splitter moved to inside the house? Would it be possible to replace the 3-way splitter with a 4-way and then run an additional coax from there and remove the 2-way splitter? Having a splitter behind a splitter usually isn't a good idea (IMO) unless that's the only option.
Just sharing my thoughts. =)

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 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?

| Splitters have a funny way of behaving sometimes. Either they have no noticeable* effect at all on the signal (as they should) or they make it worse. If you can bypass that 2-way splitter altogether, then by all means do so. It may or may not help. But it's always worth a shot. =)
*EDIT - Added for clarification.

I've tried.
1. Bypassing the router alone
2. Bypassing the splitter alone.
3. Bypassing the Router And the Splitter together.
4. changing my Rwin to a higher value.
etc..
5. Getting a new IP address
I see no increase in my test speeds. This is beyond annoying since I have a new line installed outside.

In the process of doing their jobs, they do introduce a definite and labeled amount of attenuation when inserted into the coax line.
I'm speaking of "passive" splitters here. Not active ones, or DC Taps. |

Yes, there is, but it shouldn't be to the point where it's noticeable. I should have clarified that in my post. 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.
Guess it depends on one's definition of the word "noticeable" ? |

This may or may not have anything to do with your problem,but.
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.
Just a thought. |

Based on what has been said and what I am seeing here, I can only think of 2 other things. 1, have you/Comcast tried replacing the modem with a different one?
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. Ask as many neighbors as possible, cause one might not be enough to get a good result. |

What is 'live linux disk and how would this help my connection speeds? 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. |
