Settings - Wifi Settings

Im trying to access my wifi settings on my new Toshiba Tv.

I have no ‘Menu' or ‘Settings' button on my remote or TV.

I need to connect my tv back to my internet.

I've tried pressing the Vol- and no 9 on remote - doesn't work.

And I've tried pressing Mute on tv remote x2 and then holding it for a few seconds - doesn't work either..

Please please any suggestions.
