As you know the Sony Tablet S and Android are not compatible using Ad Hoc networks.
I know there is some patch. Here i was reading: szym.net Ľ Ad-hoc Wifi in Android
the WifiManager in stock Android ignores ad-hoc networks. There are a couple ways around this:
What thing i must do for have ad-hoc support in wpa_supplicant
- One is to modify the Android framework to support ad-hoc networks (I recall seeing some custom ROM for Samsung Moment that had this).
- Another is to manually configure the wpa_supplicant to connect to an ad-hoc network.
- Yet another one is to patch the wpa_supplicant to pretend that ad-hoc networks are regular access points.
I have been reading if you fail doing it your Wifi could be disabled and damaged
