Windows XP limits broadband connection speed, does it mean that we can transform the operating system and get faster Internet access?
Answer: Broadband networks are gradually entering the home and are widely used, but the web browsing speed, uploading and downloading speed of some broadband network users is not satisfactory. In fact, in Windows 2000 or XP, by modifying the registry, we can greatly improve the speed of the broadband network and truly enjoy the fun of surfing the Internet at a fast speed.
Run "regedit" to open "Register Manager"; then, click the following path to find HKEY_LOCAL_MACHINE＼SYSTEM＼CurrentControlSet＼Services＼Tcpip＼Parameters.
Right-click the corresponding blank space on the right of the "Parameters" subkey, select "New" → "DWORD Value", name it "DefaultTTL", then right-click the mouse to select "Modify", and modify its value to "80" (hexadecimal) or 128 (decimal) in the pop-up window.
Then create the following "DWORD value" in turn and modify its value (if there are two values, the former is hexadecimal and the latter is decimal):
“EnablePMTUBHDetect”=“0”
“EnablePMTUDiscovery”=“1”
"GlobalMaxTcpWindowSize" = "7FFF" or "32767"
“TcpMaxDupAcks”=“2”
“SackOpts”=“1”
“Tcp1323Opts”=“1”
"TcpWindowSize" = "7FFF" or "32767" (93440 or 186880 or 372300, depending on the network situation)
Then save our modifications, restart the computer, and you can enjoy the fun of higher network speeds.
