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.
