Wireless clients on 802.1x networks use DHCP to get IPs. Radius is not 

You can on some APs put the client into a different VLAN using radius 
attributes in the reply, and configure the DHCP server to hand different 
IPs out. Consult your AP documentation for details, but typically if the 
AP uses the "standard" way of doing it:

user1	User-Password := "something"
	Tunnel-Type = VLAN,
	Tunnel-Medium-Type = IEEE-802,
	Tunnel-Private-Group-Id = "123"
