Hi All,
I'm now using device based on windows ce 5.0 and I can connect through wifi to AP which configured Open-System + no encryption or Open-System + WEP encryption. But when trying to connect to WPA-PSK + TKIP encryption, always failed. I use the netui provided by MS to configure wifi setting.

So I check the driver code, and found that when connecting, the association is successful, then AP send EAPOL-Key to start four-way handshake but the WZC (Wireless Zero Configuration) didn't react, instead WZC send EAPOL-Start to start 802.1X authentication. (Which I think only used for WPA, not WPA-PSK). So AP think the something wrong with the device and failed the connecton.

I deeply check the netui code, found when select WPA-PSK, the enable 802.1X authentication check box is forced to be checked. So I modify the code, set it as unchecked, and it turns to be WZC don't send EAPOL-Start but still no reaction to EAPOL-Key.

I think netui only configure this struct to setting WZC about WPA-PSK:
typedef struct _WZC_EAPOL_PARAMS
{
BOOL bEnable8021x;
DWORD dwEapFlags;
DWORD dwEapType;
DWORD dwAuthDataLen;
BYTE *pbAuthData; // Pointer to provider specific config blob

} WZC_EAPOL_PARAMS, *PWZC_EAPOL_PARAMS;
I tried many kinds of settings but still not work.

Does anyone know something about this and could give some information? Thanks!

It seems that no one can help me......

WZC is not open source, I can't find a way to find out what's wrong.I hate proprietary software!!!

I am trying to write some code based on wpa_supplicant to take place of WZC, hope it will help...
