Here's a classic tweak for broadband or dial up internet connection of computers with Windows XP Pro.
- Make sure you are logged-in as Administrator.
- Now, click Start/Run and type "gpedit.msc" (w/o the quotes).
- Expand "Local Computer Policy".
- Expand "Administrative Templates".
- Expand "Network".
- Click to highlight "QoS Packet Scheduler".
- In the right pane, double-click "Limit reservable bandwidth".
Important: If a bandwidth limit is set for a particular network adapter in the registry, this setting is ignored when configuring that network adapter.
Hope this helps.
- In the Setting tab, check "Enabled".Then change "Bandwidth limit (%)" to 0 (zero).
- Reboot your computer for the changes to take effect.
Hope this helps.
