Hi,
Thanks for reply.

I am having T61 thinkspad laptop.
Miniport driver is provided by company. NIC is intel wireless wifi link
4965AG.

I am calling using IOCTL_NDIS_QUERY_GLOBAL_STATS.

Err... then all I could say that the driver should be ok, unless you have some outdated version.
Does the Windows WZC GUI see both items?

The second item looks garbled (SSID="S_HAL009" at 12DBF2);
does it come from your own wi-fi driver?

Hi,
Thanks for reply again.
I have tested code which you suggested but unfortunately It could not work.
Please sugget me what should I do?

stBSSIDList = *(NDIS_802_11_BSSID_LIST_EX *)OidData;
PNDIS_WLAN_BSSID_EX pstBSSSID = &stBSSIDList.Bssid;

for(iBSSIDCounter = 0; iBSSIDCounter < stBSSIDList.NumberOfItems;
iBSSIDCounter++)
{
memcpy(szSSID, pstBSSSID->Ssid.Ssid, pstBSSSID->Ssid.SsidLength);
szSSID[pstBSSSID->Ssid.SsidLength] = '\0';

pstBSSSID = (PNDIS_WLAN_BSSID_EX)((char *)pstBSSSID + pstBSSSID->Length) ;

}

Hi,

But it does not work with you suggested change. My Code is:

stBSSIDList = *(NDIS_802_11_BSSID_LIST_EX *)OidData;
PNDIS_WLAN_BSSID_EX pstBSSSID = &stBSSIDList.Bssid;

for(iBSSIDCounter = 0; iBSSIDCounter < stBSSIDList.NumberOfItems;
iBSSIDCounter++)
{
memcpy(szSSID, pstBSSSID->Ssid.Ssid, pstBSSSID->Ssid.SsidLength);
szSSID[pstBSSSID->Ssid.SsidLength] = '\0';

pstBSSSID = (PNDIS_WLAN_BSSID_EX)((char *)pstBSSSID + (pstBSSSID->Length +
pstBSSSID->IELength + 20));

}

Please suggest me what is wrong in my code.> With regards

thanks

Perhaps a structure packing/alignment issue. Something simple you have
overlooked.

I know that given the pointer pBssid to a valid Bssid, the next Bssid
is really at pBssid += pBssid->Length.

The code snippet refereced PNDIS_WLAN_BSSID, not PNDIS_WLAN_BSSID_EX.
However, either will work. (I just tried it to make sure...)

It's hard to provide more help. The code fragments provided are from a
working application. The executable that uses these fragments can be
found at the URL:

http://www.pcausa.com/Utilities/ndistools.htm

My only further suggestion is that somewhere along the line you have
introduced peculiar structure alignement artifacts.

Good luck,
