Problem configuring wireless card (setting SSID and other params)

Hello,

I'm trying to configure my 802.11g wireless network card using
DeviceIoControl and NDISUIO interface.

First, I request current SSID from the card. Then I set it to my
specific value using code below. Set operation returns success. And
then I request SSID again to verify if the set operation really
succeeded. But I get the same values as it was before my SET, so
network card doesn't switch to new SSID. The same situation if I try
to change infrastructure mode (OID_802_11_INFRASTRUCTURE_MODE) and
configuration (OID_802_11_CONFIGURATION). Trying to do
OID_802_11_DISASSOCIATE before sending or requesting any data returns
success too but doesn't help.
My be I'm missing some obvious things (wait, reset, additional
operations)?

Configuring card with manufacturer's utility works fine, howewer.

I know about the issue that NDISUIO is now reserved for use by
Windows, but with my own driver (derived from NDISUIO sample)
situation is the same.
Tested on systems with WinXP SP1 and SP2. WZC is turned off.

Any siggestions, links, etc would be highly appreciated!

TIA,
Serhiy


requesting SSID value:
---------------------

UCHAR QueryBuffer[sizeof(NDISUIO_QUERY_OID) +
sizeof(NDIS_802_11_SSID)];
PNDISUIO_QUERY_OID pQueryOid;

pQueryOid = (PNDISUIO_QUERY_OID)&QueryBuffer[0];
pQueryOid->Oid = OID_802_11_SSID;

bSuccess = (BOOLEAN)DeviceIoControl(Handle,
IOCTL_NDISUIO_QUERY_OID_VALUE,
(LPVOID)&QueryBuffer[0], sizeof(QueryBuffer),
(LPVOID)&QueryBuffer[0], sizeof(QueryBuffer),
&BytesReturned, NULL);

setting SSID value:
---------------------

UCHAR SetBuffer[sizeof(NDISUIO_SET_OID) - sizeof(ULONG) +
sizeof(NDIS_802_11_SSID)];
PNDISUIO_SET_OID pSetOid;

pSetOid = (PNDISUIO_SET_OID)&SetBuffer[0];
pSetOid->Oid = OID_802_11_SSID;

PNDIS_802_11_SSID psSSID = (PNDIS_802_11_SSID)pSetOid->Data;
psSSID->SsidLength = strlen((char *)pSrcSSID);
memcpy(psSSID->Ssid, pSrcSSID, psSSID->SsidLength);

bSuccess = (BOOLEAN)DeviceIoControl(Handle,
IOCTL_NDISUIO_SET_OID_VALUE,
(LPVOID)&SetBuffer[0], sizeof(SetBuffer),
NULL, 0,
&BytesReturned, NULL);

 

At least, Disassociate should work.
So you might be doing something wrong - in our business every single bit
matters...

Additional advice : Check in debugger ( windbg e.g.) if you send the same
data as WZC to Ndisuio
