Hello, Welcome to the User Discussion Forums. If you are able to connect everywhere but at home, first make sure you have updated your router to the latest Firmware update if applicable. If still you are unable to connect we would recommend speaking with a tech support specialist to guide you through your home networking issues. http://esupport.sony.com/US/perl/suppor ... ype_id=110
I couldn't connect to wifi at first on my tablet. You have to change it from DHCP to Static and enter the correct information. I found out about this from the Sony live chat support. After you get it online, update the operating system and the problem will go away.
