Increase your internet speed - For USB / NIC modem

If your modem (ADSL) connected through USB or NIC (Network Interface Card), there is a trick to gain more speed

This trick creates a special buffer which is in charge of better handling the interrupts between the NIC and the ADSL modem. This buffer properly works on computers with at least 256 MB of RAM.

Firstly get the IRQ for the NIC. Go to Start > Run and type msinfo32.exe which will open the System Information Console. Now go to Hardware Resources > IRQs. In the right panel, you will see all the hardware along with their IRQs. Look for your NIC’s IRQ.

For those using an USB ADSL modem, follow the procedure. Right click on My Computer and select Properties.

Select the Hardware tab and click on device manager. At the bottom of the list you got Universal Serial Bus controllers. Click on it to expand and there you can see USB root hub. Double click on it and go to power management. There you should find the USB ADSL modem along with its IRQ. If it is not located under this USB root hub just get the properties for another until you find it.

Next step is editing the system.ini file. To edit it go to Start > Run and type sysedit.exe. In the newly appeared window, select the System.ini window. Here locate [386enh], place the cursor after it and hit enter. A new blank line will be created. Now type IrqX=4096. The X represents the IRQ you obtained before. Go to file menu and save the new configuration. Restart the computer and you are done.
