I own a Sony Xperia Sola MT27i and I have bought it recently. It is working fine but then I am having issues with wifi. It is connecting fine to my home network but does not stays connected even when the signal is high. I have tried using other phones and I am not having any such issues with the same. They are connecting and staying connected until I disconnect them. I am quite sure that there is nothing wrong with my home network but then it is with the phone. Is there anything I can do about this?? Any suggestion?
