Toshiba tv cant see wireless network

Hello,

I have a 55sl417 model toshiba tv. When I attempt to set up the wireless network I don't get far because the tv doesn't 'see' my network (it doesn't appear on the list of available networks ... that list is long as I live in an apt. building). I have a dual band d-link router that creates both g and n networks ... the other devices in my house are finding and using both networks without trouble.

Thanks for any pointers you can provide.

Nick
