What is in fact QoS Packet Scheduler?
Note. This only effects LAN TRAFFIC and not INTERNET ACCESS SPEEDS. Also, in order for this to work, QoS Packet Scheduler must be supported on both sides of the connection.
QoS Packet Scheduler is a method of network bandwidth management that can monitor the importance of data packets and depending upon the priority of the packet, give it higher or lower priority or bandwidth levels.
Normally, if your system's LAN cards don't support QoS Packet Scheduling, you don't have to worry about it.
But, if you want to disable it, you can change it by doing the following. Note, this is not available in Windows XP Home Edition.
So cut the bullcrap coz it does Sh1t.
