Small business network with separate wireless/wired LANs

We are merging with another accounting firm (totaling 20 users altogether) and will be utilizing Comcast Small Business internet/phone. We have a new server w/2012 R2 and want to keep wireless from accessing the wired network. The plan is is to connect the wireless APs directly to the Comcast router (DHCP 192 net) and put a Cisco ASA between the router and internal switch (10.1.1 net). Will I have to setup 4 separate VLANs for this? What is the easiest way to allow the best speed etc.? Thanks! AJ

Thanks. We'll let you know when a new response is added.

You have basically answered your own question.  Creating two vlans is the best way to keep the sections separated.  So, when you setup your wireless, create a different vlan for it by changing the third octet of the address.  Also, when connecting the two routers, don’t forget to use a cross-connect cable.  A regular straight-through cable will not work. 

If you really want to plan it out and test it, download Cisco Packet Tracer and input your addresses and test it.  This will save you many man-hours and frustration on what went wrong where.
