Speeding up xDSL/Cable broadband in Windows 2000/XP/2003
August 5, 2007 by BeHE
If you have cable or xDSL broadband, then you can drastically speed up your connection with the following instructions.
There are three methods to this solution: The Completely Manual Way (hardest), The Semi-Automatic Way (easy), The Fully Automatic Way (easiest)
The Completely Manual Way
- Go to Start > Run
- Type regedit.exe in the box and press ENTER.
- Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
- Create a new DWORD value SackOpts with value 1
- Create a new DWORD value TcpWindowSize with value 5ae4c
- Create a new DWORD value Tcp1323Opts with value 3
- Create a new DWORD value DefaultTTL with value 40
- Create a new DWORD value EnablePMTUBHDetect with value 0
- Create a new DWORD value EnablePMTUDiscovery with value 1
- Create a new DWORD value GlobalMaxTcpWindowSize with value 5ae4c
- Close Registry Editor and reboot your computer.
The Semi-Automatic Way
Copy the following into a text editor (e.g. Notepad) and save as “netspeedup.reg” (with quotes).
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
Double-click the file in Windows Explorer and click Yes at the prompt.
The Fully Automatic Way
Download the file: dslcable_speedup.reg (scanned for viruses using ClamWin on 2007-08-05), and open it, clicking Yes at the prompt. Reboot your computer.
