Determining if the wifi password is incorrect

Postby arao23 » Fri Dec 30, 2016 10:49 pm

I'm trying to determine whether the client-entered WiFi password is correct or not. What I did was listen for the SYSTEM_EVENT_STA_DISCONNECTED event to get the reason code.

I get either WIFI_REASON_AUTH_FAIL or WIFI_REASON_4WAY_HANDSHAKE_TIMEOUT when I enter an invalid password (e.g. too short, or password doesn't match the AP password, etc). I'm not sure if this behavior is just my router or if there are other reasons I should be checking as well :)

I figured I would test your findings and I get exactly the same as you do. When I try to connect to my access point and provide an invalid password, sometimes I get reason code 15 (WIFI_REASON_4WAY_HANDSHAKE_TIMEOUT) and sometimes I get 202 (WIFI_REASON_AUTH_FAIL).

My router is a Netgear WNDR3400v3.

Under the current build I am for some reason getting WIFI_REASON_AUTH_EXPIRE for incorrect passwords. This is for a NetGear WNDR3700. I'm seeing WIFI_REASON_NO_AP_FOUND if the SSID isn't present, which is OK, but I never see WIFI_REASON_AUTH_FAIL.

Do we know something about this problem?
I only in some cases got WIFI_REASON_AUTH_EXPIRE, mostly my reason code is 0 with the wrong password.

Thanks

I do not get any events at all for wrong password for the last few months of the master branch.
