Java android connect to wifi

можете подсказать, в чем ошибка?

public void connect(View view) throws InterruptedException {

    WifiManager wifi = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    EditText passEdit = (EditText) findViewById(R.id.pass);
    EditText ssidEdit = (EditText) findViewById(R.id.ssid);
    TextView errorView = (TextView) findViewById(R.id.errorV);

    String ssid = ssidEdit.getText().toString();
    String pass = passEdit.getText().toString();

    if( !connectToKnownWiFi(wifi, ssid) ) {
        boolean isSuccess = connectToUnknown(wifi, ssid, pass);
        wait(1000*20);
        if( !isSuccess ){
            errorView.append("Error while connecting");
        }else if(isSuccess){
            errorView.append(wifi.getConnectionInfo().toString());
        }
    }
}

Пытаюсь подключится к wifi сети, пароль и ssid сети правильные. Ошибок не ловлю. Перерыл весь гугл.
