What are the steps to properly setup a WiFi network with 4 or 5 Airport base stations? I have a mix of Airport Extreme and Airport Express base stations, a switch and a modem/router with VoIP and other features which require to keep the modem configured as a router.
Of course the modem/router is connected to the switch and so should be all the base stations.
Can I get a reliable roaming going between the base stations? What are the things I should configure to make the roaming as seamless and speedy as possible?

X4 Airport Extreme
X1 24 ports switch (with some Gbps ports)
X1 modem router
