Dell的电脑，

From what I've found is that a registry key is being written at system startup.

HKLM\SYSTEM\CurrentControlSet\services\NlaSvc\Parameters\Internet\EnableActivePolling

Using the Process Monitor utility from Microsoft you can capture ZEROCONFIGSERVICE.EXE (That runs out of c:\program files\intel\wifi\bin)  writing the value 0 (turning off polling)  (You can check this, by changing the value to 1, disabling the nic, enabling the nic)  The laptops with the issue are DELL LATTITUDE E6540.
