HI to all !How can TO increase my broadband connection speed in Windows XP/2003?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 modemFollow these steps: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.Lamer note: IRQs and modem names might vary...Step #2 - Modify the system.ini fileFollow these steps: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.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 and let me know what you find.
 
so. such a usable and readable post...
 
Seems nice. Will try it out and tell u !Hey 1 problem with my pc ! I hv two NICs with me. One with local SIFY LAN and the other with the ADSL Dataone modem. In SysInfo ..both shows IRQ 16. If i modify the settings, with there be any harmful effect in my SIFY LAN ?? Anyway, am gonna try this and let u know wat happens ! If u hv any solution for my question .. pls reply !
 
Looks nice, specially the "Lamer Note " 😉
 

me already getin FULL speed n cool satisfaction with my adsl2 64/18 ,,will it help my uploads ....or jus help the way things work in the comp :?
 
I don't want to blame/ quote anyone here and am very sorry to say it's a beautifully crafted urban myth. This so called trick/ tweak doesn't work...Why the System.ini Tweak Doesn't Work...The claim is that the tweak (IRQn=4096) improves network performance by allocating 4 megabytes of memory as a buffer for the IRQ 👎 used by your network adapter. However:The setting has no effect on actual memory allocation. The setting does not actually affect network performance in carefully controlled tests. (Anecdotal reports are mixed, and unreliable due to Internet and system variabilities, particularly the effects of caching.) There is no apparent evidence that there even is any such setting in Microsoft documentation. Windows does not allocate buffer memory for IRQ's. (Buffers are the responsibility of device drivers, which allocate them by device, not by IRQ. On the PCI bus, a single IRQ can be shared by multiple devices.) While it doesn't help, the good news is that (like TTL) this setting doesn't hurt (assuming you don't screw up your SYSTEM.INI file) -- Windows just ignores settings that it doesn't recognize.Note: This may have gotten its start as confusion over the real SYSTEM.INI settings COMnIrq and COMnBuffer, which are used to control serial port IRQ assignment and buffering (the latter of which can help serial port throughput). But these settings pertain only to the standard Microsoft serial port driver, not to network adapters.
 
Nice thread, in the sense that two new members made their first post here, both posts seem well detailed, well crafted and . . . . directly contradict each other. To me post #8 seems to make more sense.

Welcome to the forum invisiblebond and MasterMind 🙂
 
thnx invisible bond...my irq is 17 n nic is realtek famil fast ...i wis h it wrks...i hope my download rate becomes faster by this....🙂...ill let u k...bt dude is it k if i have 2 irq 17's..1 is realtek n d othr is cmedia audio device...will it harm my connection ny how?:-/
 
i read the same trick for speeding up hdds..... where u just have to enter ur HDD irq no. instead of the nic irq. so i dont think it really works! :S
 
dont try to use tricks with your net, if you dont know, wrong settings can cause less speed,
