This tip is designed for increased BROADBAND speed in Windows XP while using standard Network Interface cards (NIC) that are connected to ADSL modems...
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.
This tip is only recommended if you have 256MB RAM or higher.
Here's How:
Step 1:
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(R) PRO/100+ Management Adapter). Note the IRQ next to the specified line (in my case - IRQ21).

Step 2:
1. Click Start | Run then type SYSTEM.INI
2. Scroll down almost to the end of the file till you find a line called [386enh].
3. below [386enh] type:
IrqX=4096
X = is the designated IRQ number we found in Step 1, in my case it's IRQ21.
(NOTE: This is CASE SENSITIVE!)
4. Click File | Save

5. Close the file and reboot...
Done. Speed improvement will be noticed after the computer reboots.
Update: The most speed improvement is visible with USB A/DSL modems, however there are reports that this tweak also does good for regular NICs. In any case, it won't harm your system, so why not try it yourself...
