I have three routers in my house to improve range: one in basement, one on main level and one upstairs. All are hardwired via ethernet.
As it stands, they are three separately named SSIDs. I read somewhere to change all SSIDs to the same. My question is, how will a device (your phone for example) know to switch to the stronger SSID when it needs to?
For example, if I'm upstairs I can see all three networks on my phone. The strongest being the upstairs router, obviously. If I connect to it and then walk to the basement how will my phone know to switch networks? Does it have to wait until it just LOSES connection to the upstairs router and then attempts to reconnect to the strongest? Since all three routers are accessible (to varying degrees of strength) on all three levels, I'm confused about how this 'hand off' process might work?
