  • Sony Xperia you won't connect to home Wi-Fi but connects to everything else? My brother just got his sony xperia you and it won't connect to our home Wi-Fi. My iPhone 4s, my sister's iPhone 4 and my dad's HTC desire all can connect to our home password protected Wi-Fi. However, my brother's sony xperia says connected with limited connectivity. We went to the local mcdonals and my cousins house and all those connections work. What is wrong with our home Wi-Fi?
