Steps for Boosting up your broad band :
- Open your registry and find the key below.
- Create the following DWORD values, and these values will not already exist you will need to create them by clicking on '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.
