My router (Airport Express) is upstairs and TV downstairs. The TV is having difficulty establishing a strong connection to the router. 1) Is it possible to create a separate 2.4GHz connection on my Airport? I understand that 2.4GHz is better at transmitting through walls, so I'm thinking maybe this would help. 2) Is it even necessary to do so? The Airport Express is simultaneous dual band. So even if my laptop upstairs is connected to a 5GHz band, should the TV be able to connect to the 2.4GHz band? Thank you for any help.
