Overview of HyperNet
 
If you are tired of slow internet connection, then try out HyperNet .

HyperNet is a Utility designed to fine tune windows hidden internet settings, decrease fragmentation of data packets, force even IP Packets through server lines, Increases the download speed and decreases the download time on the internet.This tool is compatible with all Major Versions of Windows 95, 98, 98SE, ME, NT4.0, 2000 , plus it supports Dialup Connections with modem speeds of 28kbps, 33.6kbps, 56kbps and High speed connections such as LAN, DSL, ISDN, Cable Modem, Satellite Connection and T-1 connections with speeds of over 100 Mbps. It fine tunes all these connections to boost speed to it's limits.

User's Guide and Description of Terms.

Maximum Transfer Unit (MTU)

Different data protocols have different package sizes that cannot be exceeded. Knowledge of the Maximum Transfer Unit is required by TCP (Transmission Control Protocol) so that the package sizes can be optimized to prevent fragmentation during transmission across the internet. 

Maximum Transfer Unit controls the way in which data TCP/IP Packets are received. This is the default packet size that Windows uses to negotiate with. When a connection is opened between two computers, they must agree on an MTU. It’s done by comparing MTUs and selecting the smaller of the two. If the MTU is set too large for routers that are between the computers, these routers then fragment this information into a packet size that the router can handle.This fragmentation can double the amount of time it takes to send a single packet. Windows has a built-in MTU Discovery that will adjust for this by sending out a packet that is marked as "Not Fragmental". Then the router sends back an error to the computer saying that the packet was too large, and Windows then lowers the MTU until there are no more errors. If your ISP uses an MTU of 576, then every time you start a connection, Windows must adjust down to this value. Even though Windows automatically adjusts the packet size, it still takes it time to negotiate an acceptable MTU.

The best and recommended settings for different connections are below :

Receive Window (RWIN)

Receive Window, is the amount of unacknowledged data than can be outstanding on a TCP connection.The TCP Receive Window size is the amount of receive data (in bytes) that can be buffered at one time on a connection. The sending host can send only that amount of data before waiting for an acknowledgment and window update from the receiving host.
Windows can only store one system-wide value for RWIN.

The best and recommended settings for different connections are below :

Time to Live Archive (TTL)

TTL is a field in the IP header which indicates how long a packet should be allowed to survive before it is discarded. This value specifies the maximum number of routers that a packet may be forwarded through on to its destination. TTL essentially determines the maximum number of hops permitted. Windows 95 and 98 default value is 32 .Setting the value to high will increase the time taken to detect dead packets. Setting it too low can prevent packets from reaching their intended destination.

The best and recommended settings for different connections are below :

Path Maximum Transfer Unit (PMTU)

The best and recommended settings for different connections are below :

HTML Extract Time-Outs

This value is set to none by HyperNet , So that you do not get many time outs during browsing.

Read Ahead Auto Scrolling

Windows Default value is disabled. But most systems get a better result by enabling this value.

Ndi Cache

Windows Default value is 0. But most systems get a better result by using  16 value. Use 32 or 64 only if 16 doesn't works.

TCP 1323 Opts

Recommended setting is 3.This option is only available and applicable to high speed connections such as DSL/Cable Modem/Satellite/T-1,etc. The possible settings are 0 - No Window scaling and Timestamp Options, 1 - Window scaling but no Timestamp options, 3 - Window scaling and Time stamp options.)

Sack-Opts and MaxDupAcks

It means support for Selective Acknowledgments (SACK) and Maximum Duplicate Acknowledgements allowed. This option is also only available and applicable to high speed connections such as DSL/Cable Modem/Satellite/T-1,etc.
Recommended setting is Enabled.

The Check Box settings

• Auto find PMTU checkbox setting
  Enabling this setting causes TCP to attempt to discover the Maximum Transmission Unit (MTU or largest packet size) over the path to a remote host. By discovering the Path MTU and limiting TCP segments to this size, TCP is supposed to be able to eliminate fragmentation at routers along the path that connect networks with different MTUs. This requires implementation of the corresponding server side algorithm, however, and presupposes all of the servers on the entire Internet only running MSFT server software with server-side optimization features accessible from MSFT web-browser client software. Needless to say, this is rather unlikely. Nevertheless, it is not recommended to disable this setting as it would then cause an MTU of 576
  bytes to be used for all connections that are not to machines on the local subnet. Disabling this setting can cause severe performance degradation because fragmentation may not be compensated for.

The best and recommended settings for Auto find PMTU on different connections are below :

• Auto Detect Black Hole checkbox setting
  This specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP(Internet Control Message Protocol) fragmentation-needed messages. With this feature enabled, TCP will try to send segments without the Don't Fragment bit set if several re-transmissions of a segment go unacknowledged. If the segment is acknowledged as a result, the MTU will be decreased and the Don't Fragment bit will be set in future packets on the connection. Enabling black hole detection increases the maximum number of re-transmissions performed for a given segment. Setting this parameter when it is not needed can cause performance degradation. However, if the router is not sending back the ICMP messages, then PMTU Discovery will not work causing an even greater loss of performance.

The best and recommended settings for Auto Detect Black Hole on different connections are below :

The Auto Button

Use the Auto Optimize button for Automatically optimizing your connection with the best setting possible.

Modem Dialing Speed

• Default - Sets the value to Windows default.
• Medium - Faster, works on most systems (Recommended)
• Fast - Fastest, makes the modem dial super fast but may not work on some systems.

Restore Defaults

Restores all settings to original windows defaults.
