There is a boot start service called “qcwlan“ which needs to be started for wifi adapter, but its failing at boot time, and when i cross check through “net start qcwlan“ then it gives “System error 2 has occured. The system cannot find the file specified.“ but when i check through “sc qc qcwlan“ the service added successfully, and when i gone to its registry under “SYSTEM\CurrentControlSet\Services\qcwlan” four things “DriverMajorVersion, DriverMinorVersion, NdisMajorVersion, NdisMinorVersion“ are missing compared to the system where wifi adapter starting, and also in its Enum section there is a key created “INITSTARTFAILED set to 1“. anyone have idea about it like why it is failing and what is the solution of it?
