Can't get WPA2 Enterprise (EAP-TLS) to connect to wifi AP using nrf5340/nrf7002/NCS2.9.0

[BrianW]

I am trying to get the wifi stack to connect to a wifi AP using WAP2 Enterprise (initially just with identity and eap_password, later with full ca_certificate check and client certificate).

We have a custom PCB with nrf5340, nrf7002, and an application built with NCS2.9.0.

The code will connect ok when using WPA2-PSK and WPA3-SAE, but doesn't manage to connect using WPA2-EAP-TLS?

To try to determine why, I have enabled WPA2-Enterprise connection in the wifi-sta sample but this doesn't connect either.

wifi-sta prj.conf file:

4300.prj.conf

The connection setup code is like this:

static int __wifi_params_wpa2eap(struct wifi_connect_req_params *params)

{

    params->timeout =  CONFIG_STA_CONN_TIMEOUT_SEC * MSEC_PER_SEC;

    if (params->timeout == 0) {

        params->timeout = SYS_FOREVER_MS;

    }

    /* Defaults */

    params->band = WIFI_FREQ_BAND_UNKNOWN;

    params->channel = WIFI_CHANNEL_ANY;

    params->security = WIFI_SECURITY_TYPE_NONE;

    params->mfp = WIFI_MFP_OPTIONAL;

    /* SSID */

    params->ssid =STA_SSID;

    params->ssid_length = strlen(params->ssid);

    params->security = WIFI_SECURITY_TYPE_EAP_TLS;

    params->eap_identity = STA_IDENTITY;        //"cc2-004a";

    params->eap_id_length = strlen(params->eap_identity);

    params->eap_password = STA_PASSWORD;

    params->eap_passwd_length = strlen(params->eap_password);

    return 0;

}

Is this correct to set up a WPA2 EAP-TLS connection?

btw my wifi AP is a HP 505H using an internal database for EAP user lookup.

Hi,

I recommend updating to nRF Connect SDK v3.0.0 or later, as that version has some improvements regarding Wi-Fi enterprise.

Additionally, Wi-Fi enterprise requires X.509 certificates. If you are not providing this, it might explain why it does not work. I recommend taking a look at Wi-Fi Enterprise test: X.509 Certificate management in our documentation. Please note that run time certificates are only supported in v3.0.0 and later.

Did you enable Wi-Fi enterprise mode in prj.conf?

CONFIG_WIFI_NM_WPA_SUPPLICANT_CRYPTO_ENTERPRISE=y

I recommend testing the Wi-Fi shell sample with enterprise mode, as described in Build the nRF70 Series DK for Shell sample with Enterprise mode, to verify that you can get enterprise mode to work with your AP and board.

Best regards,
Marte

Ok, but that update broke my WPA-PSK operation... 

 Update to NCS3.0.0 broke wifi WPA2-PSK connect? 

Maybe you can shed some light on that?

Yes, thats exactly what I was trying to do but using the (simpler) wifi sta sample, see prj.conf as included above.

Ok... I see the wifi shell example, but its all using command lines to setup the connection. Do you have a C code connection params setup example (like my setup code above, but that does the certificate setup as well?)

thanks

Hi,

It seems that your client is unauthorized to access the network. You specified security type to be NONE using params->security = WIFI_SECURITY_TYPE_NONE. What happens if you change security type to params->security = WIFI_SECURITY_TYPE_EAP_TLS?
You can find security types in wifi_security_type.

Best regards,
Dejan

Ah, no, the code (line 18 in the above code samples) has:

ctx->cnx_params.security = WIFI_SECURITY_TYPE_EAP_TLS; // ==WIFI_SECURITY_TYPE_EAP ie WPA2-Enterprise with EAP_TLS authentication

Where do you see it being set to NONE?

Hi,

I saw it here at line 4.

/* Defaults */
    params->band = WIFI_FREQ_BAND_UNKNOWN;
    params->channel = WIFI_CHANNEL_ANY;
    params->security = WIFI_SECURITY_TYPE_NONE;
    params->mfp = WIFI_MFP_OPTIONAL;

/* SSID */
    params->ssid =STA_SSID;
    params->ssid_length = strlen(params->ssid);

    params->security = WIFI_SECURITY_TYPE_EAP_TLS;
    params->eap_identity = STA_IDENTITY;  //"cc2-004a";
    params->eap_id_length = strlen(params->eap_identity);
    params->eap_password = STA_PASSWORD;
    params->eap_passwd_length = strlen(params->eap_password);

Best regards,
Dejan

but then it gets set correctly at line 11....

Hi,

Can you try to remove it and retest?

BrianW said:

I meant more the role of these parameters in the WPA2 exchange with the AP. For example, if I am connecting using a client certificate and private key, do I also need to set an anonymous identity? or rather should I be passing the 'eap_identity' field with the client user name from the certificate? When is the eap_password used?

wifi_conn_req_param structure basically holds the connection parameters as passed by the user (in case of shell) or an application. It is used to configure supplicant that takes care of connection negotiation. eap_identity and eap_password are applicable for EAP methods which employ a second phase tunnel eg., EAP-TTLS and EAP-PEAP. In case of EAP-TLS, passing anonymous identity is optional. You can find additional details (enhanced documentation) in this commit.
