It depends on the AP and on the devices you are using . Having the same SSID will allow a device to connect to the 2 . 4 network when it ' s further away , and switch to the 5 network when it gets a better signal . This can be nice , but it can also cause issues on some devices who will associate on the 2 . 4 and never switch to the faster 5 . The best thing you can do is to test it with your devices in your environment . <| sep |> Yup , that ' s the first one I saw as well . <| sep |> The difference between most flight ' s first class and cheap seats is about 8 inches .

Request the emergency exit seats . You get four feet of leg room .
