writing wifi OID from windows 10 desktop user mode

Question

Hi Everyone,

    i can access native 80211 oid  OID_DOT11_CURRENT_CHANNEL through ndisuio.sys or ndisport.sys(windows sample proctol driver).

   like this:

bSuccess = (BOOLEAN)DeviceIoControl(
Handle,
IOCTL_NDISPROT_QUERY_OID_VALUE,
(LPVOID)QueryBuffer,
bufferLen,
(LPVOID)QueryBuffer,
bufferLen,
&BytesReturned,
NULL);

    When i access OID_DOT11_DISCONNECT_REQUEST (set oid  IOCTL_NDISPROT_SET_OID_VALUE), it will fail.

    In ndisprot.sys, i see the log,  NdisOidRequest return NDIS_STATUS_INVALID_OID.

    But i use  OID_GEN_SUPPORTED_LIST to get all support oids, OID_DOT11_DISCONNECT_REQUEST in the support list. 

    how can i call write a applicant to disconnect wifi connection through ndisuio.sys or ndisprot.sys?

    please help.

    Thanks in advances!

Answer 1

Is the driver actually "Native wi-fi" or (newer) WDI?

If the latter, it may not handle OID_DOT11_DISCONNECT_REQUEST: see

https://docs.microsoft.com/en-us/windows-hardware/drivers/network/wdi-oid-to-wdi-message-mapping

Why it is listed as supported in this case... no idea. Maybe for compatibility. Wi-fi is a strange can of worms.

Answer 2

my driver is WDI.

is there a way to access WDI OID from ndisuio.sys or ndisport.sys?

i want to control wifi connect/disconnect by myself, not through Microsoft native wifi apis.
