So I contacted Sony about my inability to connect my Tablet S to ad hoc wifi connections, which I believe is what others on here have found to be the case as well. Sony claims that the tablet will connect to an ad hoc connection, although their suggested fix doesn't work of course. Here is what they told me today, which is pretty useless. Seems Sony doesn't even know that ad hoc doesn't work. -original message- Subject: Re: SGPT111US/S From: Support <email@example.com> Date: 09/06/2012 1:29 PM XXXXXXX, Thank you for contacting Sony Support.
