The problem shouldn't have anything to do with the support of wireless adapters. In every case, the driver shouldn't crash the system if an adapter is not supported... getAdaptersList() opens the registry, looks for some keys where the adapter descriptions are normally stored, parses them and return the result to the DriverEntry() routine. Since keyHandle is initialized by ZwOpenKey, I suppose that this routine is not able to properly open the registry key of your wireless adapter, but for some reason it returns a successful status. Did you check the presence and the correctness of the key in question? Is it possible that the registry of the machine is somehow corrupted?
