Increase available bandwidth for network connections
This will help increase your bandwidth for any network connection in Windows XP PRO.
1. Make sure your logged on as actually “Administrator”. do not log on with any account that just has administrator privileges. To log in as an administrator:
-click on start->logoff->logoff
-in the logon screen hold Ctrl+Alt+Del.
-in the user field type ‘Administrator’ <-case sensitive.
-in the password field type the password for the administrator (if you don’t have one leave blank)
-press ok
2. Start - run - type gpedit.msc
3. Expand the “Computer configuration” branch
4. Expand the “Administrative templates” branch
5. Expand the “Network” branch
6. Highlight the “QoS Packet Scheduler” in left window
7. In right window double click the “limit reservable bandwidth” setting
8. On setting tab check the “enabled” item
9. Where it says “Bandwidth limit %” change it to read 0– Click apply, OK, exit gpedit.msc
10. Go to your Network connections (start->my computer->my network connection-> view network connections). Right click on your connection, choose properties then under the General or the Networking tab (where it lists your protocols) make sure QoS packet scheduler is enabled.
11. Reboot , now you are all done.
This is more of a “counter what XP does” thing. In other words, XP seems to want to reserve 20% of the bandwidth for itself even with QoS disabled. So why not use it to your advantage. To demonstrate the problem, start up a big download from a server with an FTP client. Try to find a server that doesn’t max out your bandwidth. In this case you want a slow to medium speed server to demonstrate this. Let it run for a couple of minutes to get stable. The start up another download from the same server with another instance of your FTP client. You will notice that the available bandwidth is now being fought over and one of the clients download will be very slow or both will slow down when they should both be using the available bandwidth. Using this “tweak” both clients will have a fair share of the bandwidth and will not fight over the bandwidth.

Windows XP does not reserve any portion of bandwidth for itself. A QOS aware application can request priority bandwidth but few do. Automatic update does not do this and actually has lower priority than regular applications. Even if an application does this there will be no reduction in bandwidth unless the application is actively using it. Any unused bandwidth will be available to other applications. All this tweak does is set the bandwidth that “can” be reserved.
Incidentally the claim that this setting can only be changed using the Administrator account is false. Any account with administrator rights can be used.
