I also use the cablenut adjuster. I run XP and use Qwest 1500/786 DSL. When I first downloaded the app. it contained just the four basic connections with normal and fast registry settings.
There is also an update available that covers just about all of the connection types and speeds that are in use today. Of course my configuration wasn't listed in the update, but if you read around the forum you will see that the default tweaks that were added are just baseline suggestions and are meant to cover a broad selection of ISP configurations.
I actually had to uninstall the app. then install it again cause I had tried a couple of different DSL tweaks and found out that you should only run one of those particular programs by it self.
If you run more than one your performance might actually go down quite a bit. The reason is because those programs make changes to the registry and when more than one program is trying to tweak the same reg. key,there is a conflict.
As far as I can tell it won't damage your system,but if you have more than one I suggest Uninstalling all of them and picking one to use and make sure to look over the "Read Me" file that comes with it.
If you choose cablenut, get the update and save it to the same folder as the original app. Choose the ccs file that is closest to your configuration and save it to the registry like normal. It backs up the registry before making any changes so if the ccs you choose just kills your connection it is real easy to change it back to normal. Make sure to Reboot after any teaking, even if it is just one character in one box.
After setting it up visit the forum and go to the "Tips And Tricks" link on the left side of the page in the menu. This will explain how to get your post looked at.
I have went through the process several times and have this advice. Click on the link that it provides for doing speed tests and pick the location closest to you. Before clicking "start" (at the speed test) make sure you clear your Temp. Internet files. You need to run ten tests in a row so you will need to clear the temp files before clicking start every time.
After each test, you will be redirected to a horizontal graph showing your results. Jot down the Downs/Ups for each test. When all ten tests are done pick the five best results and average them out.
Go back to that tips and tricks page and do the TCP/IP test. Copy/Paste it and post it in the Cable and DSL Broadband section in the General Information Forum. Make sure to include your OS and Your Internet Service configuration. Also include the speed average info.
It is an open site so don't make any Reg. tweaks that someone suggests unless you are sure they are trustworthy. The mods. and Adms. are obvious but watch your back.
When they respond to your post they will have you click on this link:
after you enter the values to your tweak, you might check out these app. that are located at the bottom of the page.
* Faster page loading
* Disable DNS Caching
* Increase Buffer
I use them all and have noticed positive results: especially if you have a Hosts File like "Hoster" or "MSMVP Hosts file" cause the hosts file shouldn't be any bigger than 180KB or else there is a drain in performance about every 25 minutes. The Disable DNS Caching is an easy way to fix that problem by doing exactly what it says.
I scanned all that stuff for infections and they are all clean. Hope this helps Unfortunatelly I had to learn the process the hard way but now I know Whats up and am glad to pass the knowledge on.
Almost forgot, My connection went from an average of 780dn/640up to 1160dn/760up. Occasionally I see the down around 1500 but normally it stays around 1160.
