what subnet should i use?
i have 1 router, so just have 1 default gateway..
i need 500 usable host, because i have 500 clients..
and this router will connect to 18 access point...
can i have different network for every access point, each access point i want 30 useable host..
if the network too big or have too many host, it will slow down the speed it is? because every host need to wait to broadcast...
how to design this network? what subnet should i use?
