Guess the device is connected to WLAN. Most likely it is the UAPSD mode. Using the registry, it is possible to disable the UAPSD (Unscheduled Automatic Power Save Delivery) feature of WMM (a.k.a. WMM Power Save). It may be advantageous to do this in order to improve throughput performance. The UAPSD feature is controlled through two registry values. These values reside under the key: [HKEY_LOCAL_MACHINE\Comm\Jedi10_1\Parms] The registry values are:

APSDConfiguration (a DWORD value)
CCXParams (a DWORD value)

UAPSD mode os on by default. To turn off UAPSD mode:

Set the APSDConfiguration value to 0 (0x0).
Set the CCXParams value to 5 (0x5)

To turn on UAPSD mode:

Set the APSDConfiguration value to 255 (0xFF).
Set the CCXParams value to 7 (0x7)

Hope this helps.
