I know the frustration of having a dead slow broadband...So I tried a few thing that I discover from google

1. Defaulting the XP tweaks

Here’s a simple 3 minute tweak (XP Pro only) that will increase your broadband speed.

By default (even with QoS disabled) Windows XP reserves up to 20 percent of your connections bandwidth.

To override this reserve take the following steps.

Make sure you Log on as Administrator, not as a user with Administrator privileges.

* Start > Run > type gpedit.msc
* You will see [Local Computer Policy]
* Expand the [Administrative Templates] branch
* Expand the [Network] branch
* Highlight [QoS Packet Scheduler]
* Double-click [Limit Reservable Bandwidth]
* Check [Enabled]
* Change [Bandwidth limit %] to 0 %
* Click [Apply[OK]
* Restart

Effect is immediate.

2. TCP Optimixer

* Select your advertised maximum speed from the "connection speed" slider bar.  (the maximum available bandwidth, in kilobits per second).

*Choose your Network Adapter, or check to "Modify All Network Adapters".

*Choose the "Optimal settings" radio-button near the bottom of the program.

*Click "Apply changes", and reboot when prompted by the program.
