Yes. It could be the cause of the the error. Mine is working fine whenever I connect to available wifi upon searching provided that the wifi I'm connecting into is open or does not require password. But sometimes I encounter problems connecting to an open wifi connection. My phone tries to connect then it's like it freezed, but it does not mean the phone freezed but the wifi application. This is just a minor error regarding the wifi connectivity, might be because of the connection set up of a particular wifi I'm connecting into, my device might not be authorized or there are certain number of connections allowed to this wifi.
