increase internet speed broadband/DSL[registry tweaks]

There is absolutely no doubt in my mind when i say that even if you get something like 5mb/s you'd want to get more and so the reason for this article.
Windows can really be a great operating system if you know how to work it.There few tricks that allow you to increase/optimize your broadband/DSL connection with Windows 2000 and Windows XP.
Let me warn(so in case you screw up im not the one to be blamed) you that registry editing is coming up so back up your data first. Simply create a restore point and if you dont know how the READ this.

Now lets begin our quest.

Open your registry
  • start
  • run
  • type "regedit"
find the key below.

HKEY_LOCAL_MACHINE\
SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Create the following DWORD values,

Just Right click and select "dword"

'Edit -> New -> DWORD Value' and then set the value as shown below.

DefaultTTL = "80" hex (or 128 decimal )
Specifies the default time to live (TTL) for TCP/IP packets. The default is 32.

EnablePMTUBHDetect = "0"
Specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP fragmentation-needed messages. The default is 0.

EnablePMTUDiscovery = "1"
Specifies whether the TCP/IP stack will attempt to perform path MTU discovery as specified in RFC 1191. The default is 1.

GlobalMaxTcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the system maximum receive window size advertised by the TCP/IP stack.

TcpMaxDupAcks = "2"
Determines the number of duplicate ACKs that must be received for the same sequence number of sent data before "fast retransmit" is triggered.

SackOpts = "1"
Enables support for selective acknowledgements as documented by Request for Comment (RFC) 2018. Default is 0.

Tcp1323Opts = "1"
Controls RFC 1323 time stamps and window scaling options. Possible values are: "0" = disable RFC 1323 options, "1" = window scale enabled only, "2" = time stamps enabled only and "3" = both options enabled.

TcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the receive window size advertised by the TCP/IP stack. If you have a latent network you can try increasing the value to 93440, 186880, or 372300.

Exit your registry and restart Windows for the changes to take effect.


Now if you dont want to this then leave a comment i'll give you ready made .REG file which you can any time merge into your registry just by double clicking.
