After extensive reading and running the TCP/IP Analyzer on speedguide.net, I have made the following changes:-

Set MTU To 1492 On Router
Set MTU To 1492 On Computer
Set ProtocolMTU To 1480 In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NdisWan\Parameters\Protocols\0

Set RWIN To 60984
Set TcpWindowSize To 121968 In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Set GlobalMaxTcpWindowSize To 400000 In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Set Max Number Of Simultaneous HTTP 1.0 Connections To 8
Set Max Number Of Simultaneous HTTP 1.1 Connections To 4


The result is a much faster loading of web pages.
