Connection to Sony TV from Nighthawk M5

[robh43]

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.

What is the model of the TV? Could that be old model that didn't support WiFi properly?

Thanks
