(1) if you moved and are on a different Node then you may be on a Node that has capacity issues (too many users).
(2) even thought your signal look good - there is one signal you can not see that can absolutely cause you problems and that's Upstream SNR being too low. That can only be seen from the Headend by your cable company or tools they have to check.
But a good indication of Upstream SNR probelms woujld be for you to ping the gateway about 50 to 100 pings and see there there are any timeouts - there should be none to the gateway or CMTS (1st hop past your PC or router is you have one). Also check your modem logs - frequent No Ranging Response T3 timeouts also indicate Cable Plant noise problems which maybe be just intermittant and cause you problems (again Upstream SNR).
Charter uses a program called eqa to check modem history but it can only be set to monitor at a minimum of 15 minute intervals - so if you have intermittant noise problems then the program might not even catch it and you might need someone at the headend to monitor your Node with a spectrum analyzer to cateht he problem and then send a line tech to track it down.]]> http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23294537 Thu, 05 Nov 2009 02:13:36 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23094514 said by krzyrice:

Hi I just moved houses in the last few weeks. I am on the standard 10/1 plan. At my old house my speed on Roadrunner was 22/1(with turbo) and downloading at 1.2mb per sec steady. How come here I can't even download past 700kb per sec and it jumps all over the place. And the speedtest says I'm getting 19/1(turbo). Do I have to call them up or what.
Are you testing this directly connected to the cable modem or are you using a router - if a router is being used - are you wireless?]]> http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23094514 Mon, 28 Sep 2009 11:00:06 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23094486

This is what the cable signal readout on »192.168.100.1/diagnostics_page.asp says:

Try comparing mine with yours and see if anything is lower than it should be.]]> http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23078281 Thu, 24 Sep 2009 19:10:57 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23078111
It could be simple as the node your on is over-sold. I live in Ohio and I'm on the Columbus division. Here the highest speed available is 15000/768. Which is the broadband speed I got.

When I try the 'Test512' using my RR. I get a stable 1.7 - 1.8 MB/sec. ]]> http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23078111 Thu, 24 Sep 2009 18:43:46 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23078001 http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23078001 Thu, 24 Sep 2009 18:21:48 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23076605

Change the rwin window to 146000

Click save to each adapter, and leave everything else BLANK, don't touch anything else.

Restart and try this all again.]]> http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23076045 Thu, 24 Sep 2009 13:44:43 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23075898 http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23075898 Thu, 24 Sep 2009 13:21:03 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23075302
Your TCP window is also the amount of data downloaded as soon as you click on a file.

Once you click save, it will begin downloading, but already counts the tcp window that was downloaded. This is why the download speed may appear to be faster then it should be at first, and then just keep going down during the first 5-20seconds.

You need to get yourself a program like netmeter. It will tell you the download and upload in updates of every second. And it does not exaggerate.

This way when you download a file, you will see exactly how power boost works, looking at it jumping up and down between 20-34Mbits/sec. Then dropping down after a few seconds to your normal bandwidth limit,of either 10000/512 or 20000/1000.

Try also doing ftp transfers:

open command prompt and type:

ftp ftp1.optonline.net
anonymous
abc@abc1.com
get test64

And wait for it to finish do not use your internet.

It is best to try this immediately after trying a speed test, this way power boost does not kick in and report false/higher readings during this new transfer.

This is why I hate 2-5seconds of power boost, because on a large file it really doesn't make a huge difference, and it will only make you think your downloading faster when your not!.

Please try what I said and report back.]]> http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23075302 Thu, 24 Sep 2009 11:53:34 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23074147

*I just downloaded the program and tried tweaking my system. It doesn't improve the speed at all. Also I don't think the website I am downloading from limits the download speed(Rapidshare). I always had 1.25mb steady download speed at my old house.]]> http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23072297 Wed, 23 Sep 2009 20:06:49 EDT http://www.dslreports.com/forum/Re-How-to-make-Roadrunner-faster-23071905
Keep in mind that a lot of webmasters also cap the speed at which their servers will transfer data to you. Many of them seem to keep it at 500KB/s. Many of the sites I visit have that limit or even lower, but the gaming sites that have large downloads on there have uncapped servers where regardless of the connection I'm on, if the server and network is free I'll pull Megabytes a second from them.
