This is not really a Hilton issue - should have really put it in another forum but would be interested if other hilton guests had a problem like this...
When I am downstairs I am able to connect to the Honors Wi-fi. It must use an extender that gets it to the 6th floor or another router that my tablet is having an issue connecting to... And while a weak signal I am occasionally able to connect to "Hilton Lobby" in my room.
