Apps Very slowly connecting to wifi

[Ivan Ivanov]

Hello I am new in Android and I am developing a simple app which needs just to connect the device to a particular WiFi network. However, sometimes I need to wait the phone to connect like 3-4 minutes. The code I use for connecting is the following:

WifiConfiguration robotNetwork=new WifiConfiguration();
                myNetwork.SSID="\""+mySSID+"\"";
                myNetwork.preSharedKey="\""+myPass+"\"";
                int netID=wifi.addNetwork(myNetwork);
                wifi.enableNetwork(netID,true);
                wifi.reconnect();

What am I doing wrong?

Thank you in advance!!!
