problem with NDIS miniport driver

[jhon]

Hi

We are developing NDIS miniport driver for wireless LAN card.
OS is windows XP pro SP2
Observation is,
OS sends SCAN OID, then SCAN_LIST and adapter returns scanned item.
but after that instead of sending valid SSID from this list in set
OID_802_11_SSID, NDIS sends Junk SSID.

Why does NDIS sends Junk SSID when it has retrieved valid scan list
item. Are there any security parameters we need to verify?

Note: we dont see same behaviour on Windows XP Pro (Without Service
pack)

XP SP2 returns a NDIS_802_11_BSSID_LIST_EX structure instead of
NDIS_802_11_BSSID_LIST.

You can handle both cases by advancing through the returned buffer using the
NDIS_WLAN_BSSID or NDIS_WLAN_BSSID_EX Length field.

Good luck,
