IMPORTANT TO UNDERSTAND
Remember your goal is to get about 90% of your rated speed, sometimes depending on factors beyond your control i.e. routers, servers, line quality, overloaded node etc.
YOU CANNOT TWEAK GAMMING OR PiNG SO DON'T EVEN ASK.
The Maximum Transmission Unit value should be set accordingly: 56K, PPPoA DSL, Cable Modem - 1500 / PPPoE DSL - 1492 / XP PPPoE DSL - 1480*
*Note* - With XP and PPPoE DSL your MTU can either be 1492 or 1480, make sure your settings are adjusted for the proper MTU.
56ks tweaks
A must have for xp/win2k users
A must do before any tweaks download and install both and run get rid of all spyware.
Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/
to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.
If are using zone alarm remove it it is the biggest resource hog and bandwith eater firewall there is. Use Outpost Firewall http://www.agnitum.com/products/outpost or Sygate Firewall http://www.sygate.com/, both have FREE and Pro versions and are heads above ZA.

If using a linksys router goto 192.168.1.xxx whatever your routers ip is goto advanced make sure you have mtu set
and block wan request disabled if you are paranoid about sercurity leave it enabled however when set enabled it could effect speed.
If u are using usb to connect to your cablemodem and or dsl get na network card and network cable better performance
Cable user with no router has to have network card set 10 half duplex
dsl users use 100 full duplex
HOW TO SET THE PROPER NIC DUPLEX SETTINGS:
Win98/ME: to change to half-duplex:
* Open Control Panel.
* Double-click Network.
* From the scrollable list, select your Ethernet adapter (rather than any dial-up) with a green icon.
* Click the button Properties.
* Click the tab Advanced to bring it to the front:
* In the Property box, the property name to be selected varies according to model of ethernet card. Examples are: Network Link Selection, Media Type, Connection Type, Duplex Mode, or any similarly-named property which can have Values looking like Auto-Negotiation, or 10BT, or 10BaseT.
* In the Value box, select a value which either (a) explicitly says half-duplex or semi-duplex, or (b) at least does not say full-duplex [e.g. 10BaseT on its own is OK]. If there is a choice between 10 and 100 with half-duplex, choose the 10. Do not choose 10Base5, 10Base2, or AUI.
* Click OK to exit the Adapter settings.
* Click OK all the way out - you might need to restart.
Windows 2000 or XP: to change to half-duplex:
* Open Control Panel.
* Double-click Network and Dial-up Connections.
* Identify the icon for your cable modem connection: usually Local Area Connection.
* Right-click that icon and select Properties.
* Under the ethernet adapter icon, click the button Configure.
* Click the tab Advanced to bring it to the front:
* In the Property box, the property name to be selected varies according to model of ethernet card. Examples are: Network Link Selection, Media Type, Connection Type, Duplex Mode, or any similarly-named property which can have Values looking like Auto-Negotiation, or 10BT, or 10BaseT.
* In the Value box, select a value which either (a) explicitly says half-duplex or semi-duplex, or (b) at least does not say full-duplex [e.g. 10BaseT on its own is OK]. If there is a choice between 10 and 100 with half-duplex, choose the 10. Do not choose 10Base5, 10Base2, or AUI.
* Click OK to exit the Adapter settings.
* Click OK to exit the Connection properties.
if u are using a router at set network card 100 full

Speedguide.net - Tips on tweaking
**PLEASE ANSWER THESE QUESTIONS IF YOU NEED HELP**
The answers to the following questions are VERY important when posting asking for assistance, if you do not answer them you will not recieve any assistance. You must help us help you!
1. What type of connection do you have? i.e. 56K, ISDN, DSL (PPPoE or not), Cable etc.
2. Who is your ISP and what is your advertised speed from them? i.e. Cox.net & 3000/256 - this is advertised in kilobits per second.
3. What are your current settings now? Do a TCP/IP Analyzer Test and copy and paste the results (remember to XXXXX out your IP address) here.
4. Please tell us your operating system i.e. 95, 98, 98SE, ME, 2K or XP.
*NOTE* AOL user don't bother tweaking your connection, AOL doesn't use the standard TCP/IP stack.
IMPORTANT TO UNDERSTAND
Remember, your goal is to get about 90% of your rated speed, sometimes depending on factors beyond your control i.e. routers, servers, line quality, overloaded node etc. it just isn't going to happen, no matter what you do.
MTU Values - THIS MUST BE SET PROPERLY PRIOR TO ANY OTHER TWEAKING
The Maximum Transmission Unit value should be set accordingly: 56K, PPPoA DSL, Cable Modem - 1500 / PPPoE DSL - 1492 / XP PPPoE DSL - 1480*
*Note* - With XP and PPPoE DSL your MTU can either be 1492 or 1480, make sure your settings are adjusted for the proper MTU.
EXTREMELY IMPORTANT!!!
Download, update and scan with SpyBot S&D EXACTLY as I explain HERE & Ad-aware EXACTLY as I explain HERE to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES. Spyware can and will ruin your connection and crash your pc!

The most reliable way to test your speed/bandwith is to use one of the FTP tests above. Just download about half of it (until your speed levels off) and multiply the average by 8 to see how close to your caps you are.
OTHER IMPORTANT RECOMMENDATIONS
- SETTING YOUR NIC DUPLEX MODE PROPERLY:
ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware. DO NOT CONNECT YOUR MODEM VIA USB!!
- SPEED UP NETWORK BROWSING:
* Open up regedit.
* Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Explorer/RemoteComputer/NameSpace.
Delete the key: {D6277990-4C6A-11CF-8D87-00AA0060F5BF}.
- FASTER WEB PAGE LOADING:
This tweak will help web pages load faster, it has no real effect on download speeds, just helps your pc look up websites faster thereby speeding up how fast the page loads and making web-surfing more enjoyable.
Navigate to this registry entry and change the following settings:
For XP & 2K
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ServiceProvider
For 98, 98SE & ME
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\ServiceProvider
On the right for ALL OS's change these entries: (ALL values are HEXIDECIMAL)
DnsPriority = 1
HostsPriority = 1
LocalPriority = 1
NetbtPriority = 1
To change the value right mouse click on the value and select modify and enter the values above once you have done all of them reboot to take effect and see how fast your pages load.
For 98 & ME they should look like:
01 00 00 00
- SETTING IE'S SETTINGS CORRECTLY
Open Internet Explorer and select Tools - Internet Options - under the General tab in the Temporary Internet files section select the Settings button.
Select "Every visit to the page" and set the amount of disk space to use: to no more than 100MB. Now select the Connections tab and select LAN Settings make sure EVERYTHING there is unchecked and select OK.
IE6 ONLY - select the Privacy tab and choose Advanced check the box "Override automatic cookie handling" and for First-party Cookies - Accept, Third-party Cookies - Block and check "Always allow session cookies.
Set your temporary internet cache to 100mb and delete it weekly.
- RESET YOUR MODEM REGULARLY
Another thing to do about once a week if you modem is on 24/7 is to power cycle your modem, just completely disconnect power from it for atleast 15 seconds and then power it back on.
- DNS CACHE FIX
By default Windows 2K & XP cache everything in the DNS cache service, both correct and faulty DNS lookups. To increase performance by eliminating the caching of faulty DNS lookups, change the following values from whatever their original values are to zero.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
"NegativeCacheTime"=dword:00000000
"NetFailureCacheTime"=dword:00000000
"NegativeSOACacheTime"=dword:00000000
- USE ETHERNET INSTEAD OF USB
Always connect your modem via ethernet (Network Interface Card) instead of USB, ethernet is faster and much more stable. Also make sure you have the latest drivers for your NIC from the manufacturer NOT Microsoft, alot of times the drivers from the manufacturer have advanced settings that help optimize the performance of your NIC that the native Microsoft drivers don't have.
- SCAN WEEKLY WITH FOR SPYWARE
Make sure to keep Ad-aware, SpyBot and SpywareBlaster up to date and do weekly scans.
- UPDATE YOUR DRIVERS AND FIRMWARE:
Make sure you have the latest drivers for your NIC from the manufacturer. If you are using a router make sure you have the latest firmware.
- MINIMIZE YOUR AMOUNT OF PROTOCOLS:
For 2K & XP - Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need. *Note - If using 2K & XP and you are a stand alone pc then the only protocol you need is Internet Protocol TCP/IP.
- SETUP TCP/IP PROPERLY:
(XP Only) Setting your TCP/IP metric setting properly, it should be set to a value of 1. To do so do the following:
Open your control panel – select the network icon – right click on your LAN connection and select properties – highlight Internet Protocol TCP/IP and select properties – advanced – select the IP settings tab – in the interface metric box put the value 1 – ok. Also disable NetBios over TCP/IP if you are not file or printer sharing.
- FORWARD BUFFER MEMORY TWEAK:
This value controls how much RAM TCP/IP uses for storing packet data in the router packet queue.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"ForwardBufferMemory"=dword:00024a00
"NumForwardPackets"=dword:0000024a
"MaxForwardBufferMemory"=dword:00024a00
"MaxNumForwardPackets"=dword:0000024a
*Note - These values should be adjusted according to your MTU value, the above are based on a MTU of 1500. For further explanation please read HERE.
