I've had this TV for 2 years connected to my home network (Cisco router) using WEP security protocol. This week I have upgraded to WPA2 Personnal (AES) protocol. All of my home hardware (PC's, iPad,s, iPhones...) have switched over without any problem but the TV just won't connect. After entering the password, I get a connection failed message. I have tried disabling the security on the router, reverted back to WEP also to no avail. Nothing works anymore. Help please?
