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 (Network Interface cards) or LAN Card:
(This tip is only recommended if you have 256MB RAM or higher.)

STEP#1:Identify the IRQ used by the NIC/USB modem
Follow these steps:

Open the System Information tool by running MSINFO32.EXE from the Run command.

Expand System Summary > Hardware Resources > IRQs.

Look for the listing made for your NIC (in my case - Realtek 81xxx Ethernet NIC+ Management Adapter). Note the IRQ next to the specified line (in my case - IRQ21).

Step #2 : Modify the system.ini file
Follow these steps:

Run SYSEDIT.EXE from the Run command.

Expand the system.ini file window.

Scroll down almost to the end of the file till you find a line called [386enh].

Press Enter to make one blank line, and in that line type


where X is the designated IRQ number we found in step #1, in my case it's IRQ21.

Click on the File menu, then choose Save.

Close SYSEDIT and reboot your computer.

Done. Speed improvement will be noticed after the computer reboots.
