Connection to Sony TV from Nighthawk M5

TV asks for network name which I enter then asks to select security mode from -

1. none

2. WEP

3. WPA/WPA2-PSK(TKIP)

4 WPA/WPA2-PSK(AES)

and enter security code.

Have tried them all , closest I got was on WEP but that said my security code was to long.

Appreciate any help or suggestions.
