Over the years the QoS settings under your network settings have been controversial.     I never really tried it until tonight.  To disable QoS, don’t just uncheck it under the network adapter properties.

To change how much bandwidth is reserved for QoS (the default is 20% of your total bandwidth), do the following:

1. Log in as “Administrator” (Administrator Only).
2. Navigate to START-Run (or Search in Windows 7) and type: gpedit.msc   Hit Enter.

3. Navigate to Local Computer Policy – Administrative Templates – Network – QOS Packet Scheduler

4. In the right pane, double-click the limit reservable bandwidth setting
5. On the setting tab, check the enabled setting.
6. In the  “Bandwidth limit %”, change the value to read 0 (the numeric value of zero)

7. Click OK, close gpedit.msc

Reboot your computer.

If you disable this setting (by clicking disable) or do not configure it, the system uses the default value of 20 percent of the connection.

At only .5 Mb/s down, it’s a little improvement that goes a long way.

Here’s another way to improve your networking even more.  Link

The above tips are for Professional or greater versions.   You can type services.msc and disable QoS in the Home Edition.
