You inherit two cisco switches (2 x Cisco SF300-48PP 48-port 10/100 PoE+ Managed Switch with Gig Uplinks) what will you choose next?

So... Bit of a fun challenge, I guess. And down to different perspectives... How would you get this network setup (i.e. What router, access points, etc...) to simply get the WiFi (gigabit) working over two floors in a building that fits 200 employees?
