If it still doesn't work after that, then it's a sure diagnosis the wireless adapter is bad. To be sure, I would recommend you do a complete system recovery at this point and test the wireless again. If MiniportInitializeEx failed, MiniportInitializeEx must release all resources that it allocated before it returns and the adapter returns to the Halted state.OK, if the device is "working" in device manager, but failing otherwise, and given the other symptoms, there is a good possibility this wireless device has failed. For more information, see Halting a Miniport Adapter. If MiniportInitializeEx returns NDIS_STATUS_SUCCESS, the driver should release all the resources for the adapter in the MiniportHaltEx function. For more information, see Starting a Miniport Adapter.

NDIS can call the MiniportRestart function to transition the adapter to the Running state. NET_BUFFER and NET_BUFFER_LIST pools (see Miniport Driver Send and Receive Operations).Īfter MiniportInitializeEx returns successfully, the adapter is in the Paused state. Typically, MiniportInitializeEx allocates adapter-specific resources in the following order: The miniport driver specifies the adapter attributes in the NDIS_MINIPORT_ADAPTER_ATTRIBUTES structure that MiniportInitializeEx passes to NdisMSetMiniportAttributes. The time-out interval for calling its MiniportCheckForHangEx function.A pointer to a driver-allocated context area.Obtains information about the hardware resources for the adapter.Ĭalls the NdisMSetMiniportAttributes and provides the following attributes that are associated with the adapter: Obtains configuration information for the adapter.

The adapter is in the Initializing state.Ī miniport driver typically performs the following tasks in MiniportInitializeEx: Until MiniportInitializeEx returns, NDIS submits no requests for the adapter being initialized.

For more information about miniport driver initialization, see Initializing a Miniport Driver. NDIS can call MiniportInitializeEx at any time after the driver is initialized. NDIS calls the miniport driver's MiniportInitializeEx function to initialize an adapter for network I/O operations. Subsequently, the Plug and Play (PnP) manager sends NDIS a Plug and Play IRP to start the device.

When a networking device becomes available, the system loads the required NDIS miniport driver, if it is not already loaded.
