If you have more than one access point in the building/house, what are the Pros and Cons of assigning each access point the same SSID vs different SSIDs?
If there is one SSID, how does my phone or laptop would know which one to connect? If I walk around from one corner of the building to another corner of the building, do they automatically switch to different access point device nearby?
If I give different SSID to each AP (for example, "Kitchen", "Basement", "Loft", "Master"), then users will have to make the switch to different SSID depending on which area they are in. It is inconvenient to switch every time. But a couple of advantages that I can think of: (1) When AP is down, you know which one is down because that SSID won't show up from the list of wireless network. (2) If you set up a Chromecast on your TV which requires SSID, you know which AP/SSID was used for each Chromecast device.
Having said that, what are the considerations of determining whether to use the same SSID or not when you have multiple APs?
