Before performing these steps you need to test your broadband speed
you can test your speed at http://www.2wire.com/
The broadband connection speed can be increased by clearing the route from modem to server. Number of packets sent by modem to server should be increased.Internet speed can be increased by increasing more number of incoming and outgoing packets.The main reason why your internet connection is slow is because of harmful virus.If your system is infected with virus your number of incomming packets will be decreased.This leads to your slower internet speed.Internet speed can be increased by by clearing the route to the server.
This can be done by upgrading costly sofwares and hardwares.This will optimize your system speed.And Increase your system speed.Internet tweak is the best software which increases your system speed for further applications.Another software Windows power tools which makes windows faster and increases your internet speed.And decreases downloading time.It optimizes LAN,CABLE,DSN etc.Another software "internet cyclone"which increases your internet speed from 64kbps to 120kbps.
This tip is designed for increased BROADBAND speed in Windows XP while using standard Network Interface cards (NIC) that are connected to ADSL modems, or when using any directly-connected USB ADSL modem.
To speed up the Internet connection speed we need to configure a special buffer in the computer's memory in order to enable it to better deal with interrupts made from the NIC or the USB modem.
This tip is only recommended if you have 256MB RAM or higher.
Step #1 - Identify the IRQ used by the NIC/USB modem
1. Open the System Information tool by running MSINFO32.EXE from the Run command.
2. Expand System Summary > Hardware Resources > IRQs.
3. Look for the listing made for your NIC (in my case - a Intel® PRO/100+ Management Adapter). Note the IRQ next to the specified line (in my case - IRQ21).
In case of USB modems you will first need to find the right USB device used by your modem. Follow these steps:
1. Open the Device Manager tool by running DEVMGMT.MSC from the Run command (or by right-clicking My Computer > Hardware tab > Device Manager button).
2. Scroll down to Universal Serial Bus controllers and expand it.
3. Right-click the USB Root Hub and select Properties. Note that you might need to do so for all listed USB Root hubs (if there are more than one) in order to find the right one.
4. In the Power tab, look for your USB ADSL modem.
5. In the Resources tab look for the assigned IRQ (in this case - IRQ21).
6. This is the IRQ we're looking for.
Note: IRQs and modem names might vary...
Step #2 - Modify the system.ini file
1. Run SYSEDIT.EXE from the Run command.
2. Expand the system.ini file window.
3. Scroll down almost to the end of the file till you find a line called [386enh].
4. Press Enter to make one blank line, and in that line type IRQX=4096 where X is the designated IRQ number we found in step #1, in my case it's IRQ21.
Note: This line IS CASE SENSITIVE!!!
5. Click on the File menu, then choose Save.
6. Close SYSEDIT and reboot your computer.
Done. Speed improvement will be noticed after the computer reboots.
