WPS (with WPA2) using wpa_supplicant0.6.10
Fri Dec 17 02:53:13 PST 2010
I was unable to reply to original mail . Hence creating another thread.
I am using Wi-Fi driver developed our company . After making a fix in
the driver, I am able to associate with the AP but authentication
fails at various stages. Once in around 10 times I see a success.
Another team in my company using wpa_supplicant 0.7.3 is not seeing
these issues .Is wpa_supplicant0.7.3 more stable than 0.6.10 w.r.t WPS
Meanwhile, I am investigating the issue further to rule out any issues
in our setup or ion our driver .

Which driver are you using?

This code is from the time before support for WPS was added.. Most
drivers don't really use the IW_AUTH_WPA_VERSION configuration and as
such, they are unlikely to care. This should really be replaced with use
of params->key_mgmt_suite, though.
