If we are prompted to "have problems with authentication" When we connect, the following illustration shows.
There was a problem with authentication
We can try to restart the router, this as long as the right at home, we restart it.
Reboot the Router
We touch the connection name on the phone, then choose not to save the button to connect

Problem descriptionIn the introduction of wifidog implementation of the Internet authentication function, there are 2 problems: HTTPS redirection and select detection, the former does not require users to access 80 port, the latter resulting in low efficiency. For the user experience, HTTPS cannot be actively redirected very intolerable. In my UC browser, the recommended website has a Sina, it is HTTPS, eac

Access Android keystore to store keys that encrypt/decrypt objects
Generate an encryption key and password
Start the authentication process

That's all. Next we will implement the above steps!
At the beginning, you must first enable the touch sensor and Identity

Update_config = 1
Fast_reauth = 1
Sometimes, the driver needs to be added:
Ap_scan = 1 if an AP connection problem occurs, you need to modify ap_scan = 0 to connect the driver, instead of wpa_supplicant.
To connect to non-WPA or open wireless networks, add:
Network = {
Key_mgmt = none
} 6. wpa_supplicant with the configuration path and permission modified by Google should run under

(3) configure and connect to the APWhen you select an active AP, the wifisettings response opens a dialog box to configure the AP, such as the encryption method and the Authentication Mode for connecting to the AP. After the AP is configured, wifiservice adds or updates the network to connect to a specific AP.Code example: packages/apps/settings/src/COM/Android

If you use a custom wpa_supplicant Driver (such as madwifi), you can set:
