WPA-PSK for Aironet

[Basavaraj Arani]

Hi Dan,

I am using the Firmware 5.6.08. But whenever I set the WPA key, the card
somehow doesn't get associated with the Access Point.
I am using the DLink-DWL-7100AP access point.

Here is the code for setting the WPA on/off
........
    if(!strcasecmp(args[0], "on"))
    {
        //wrq.u.param.flags = IW_AUTH_WPA_ENABLED & IW_AUTH_INDEX;
        wrq.u.param.flags = IW_AUTH_DROP_UNENCRYPTED & IW_AUTH_INDEX;
        wrq.u.param.value = 1;

        if(iw_set_ext(skfd, ifname, SIOCSIWAUTH, &wrq) < 0)
                return(IWERR_SET_EXT);

    }
    else if(!strcasecmp(args[0], "off"))
    {
        wrq.u.param.flags = IW_AUTH_WPA_ENABLED & IW_AUTH_INDEX;
        wrq.u.param.value = 0;

        if(iw_set_ext(skfd, ifname, SIOCSIWAUTH, &wrq) < 0)
                return(IWERR_SET_EXT);
    }
........

and for setting the WPA keys, I have the following code.

static int
set_wpakey_info(int             skfd,
             char *             ifname,
             char *             args[],
             int                count)
{
    struct iwreq wrq;
    struct iw_encode_ext *iwee;
    unsigned char key[IW_ENCODING_TOKEN_MAX];
    int keylen = strlen(args[0]);

    memset(&wrq, 0x00, sizeof(wrq));

    memcpy(key, args[0], keylen);
    iwee = (struct iw_encode_ext *)malloc(sizeof(struct iw_encode_ext) +
IW_ENCODING_TOKEN_MAX);

    iwee->alg = IW_ENCODE_ALG_WEP;
    iwee->key_len = keylen;
    iwee->ext_flags = 1;
    memcpy(iwee->key, key, keylen);

    wrq.u.encoding.pointer = (caddr_t)iwee;
    wrq.u.encoding.flags =  1;
    wrq.u.encoding.length = sizeof(struct iw_encode_ext) + keylen;
    if(iw_set_ext(skfd, ifname,SIOCSIWENCODEEXT, &wrq) < 0)
    {
       return(IWERR_SET_EXT);
    }
    return(1);
}

I tried to set a key of length 32.
The key I set at both the ends (AP/ client adapater) is
abcdefghijklmnopqrstuvwxyzabcdef.

But the card doesn't get associated with the AP.

Please help me in resolving this problem.

Many thanks in advance.

Regards,
Basu
