To Increase the Internet Speed:
Open Notepad and paste the below code in it.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"SackOpts"=dword:00000001
"TcpWindowSize"=dword:0005ae4c
"Tcp1323Opts"=dword:00000003
"DefaultTTL"=dword:00000040
"EnablePMTUBHDetect"=dword:00000000
"EnablePMTUDiscovery"=dword:00000001
"GlobalMaxTcpWindowSize"=dword:0005ae4c

Now save this file as speed.reg. Execute it and observe the change!

I found the above insturctions to tweak internet connection but it does not work on my PC. A dialog box says: cannot import C:|documents and setings\user\Desktop\speed.reg: The specified file is not a registry script. You can only import binary files from within the registry editor

A REG file needs to have the first line as the Registry Editor Version, then a blank line, then the registry items to change. So it should go like this:
Code:
REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"SackOpts"=dword:00000001
"TcpWindowSize"=dword:0005ae4c
"Tcp1323Opts"=dword:00000003
"DefaultTTL"=dword:00000040
"EnablePMTUBHDetect"=dword:00000000
"EnablePMTUDiscovery"=dword:00000001
"GlobalMaxTcpWindowSize"=dword:0005ae4c

However, I am not sure you will see any appreciable difference, and it could make it worse. You should back up your registry before doing this so you can put it back if you want to.

I'm not saying it will make it worse, I'm saying it may make it worse. You are changing the TCP/IP settings away from default. Can you tell me how these settings will make it better?

I don't know but the default is not necessarily the best, is it?

Default is not necessarily the best. However it is the default because in general that is the best. It can probably be improved upon for your specific setup, however I am not sure what effect these changes will make, so it could make it worse. If that's the case then you will need to undo the changes you made to put it back to how it was.

might have an effect if you have a direct connection through an ADSL or cable modem, but I can't see how this would work behind a router, as the router software is the limiting item, not the PC settings

Its actually an old registry hack dating from the early days of broadband when speeds were typically less than 2Mbit/sec. Its designed for Windows 2000 and 9x. Its really not a good idea to use on a modern system with a newer OS and higher data speeds. It could quite possibly have negative effects
