I have a toshiba tv model number 42tl515 software version 2.2.5 (3d): jun 05 2013- 14:52 . It used to connect to the Internet but now it doesn't. It does not even register any networks when I try to search for networks to connect on. I get an error message saying no Ap'so found.All other devices are connecting just fine to the wifi. We are using anow apple airport extreme wifi router. I have reset the TV and still nothing.
