Here is an example of simple configuration of wireless network on these routers (851W, 871W еtс).

In this example Network SSID: WiFi-SSID
Encryption is WPA-TKIP
WPA key: wpakey01

dot11 ssid WiFi-SSID
 vlan 1
 authentication open 
 authentication key-management wpa
 wpa-psk ascii 0 wpakey01

bridge irb

interface Dot11Radio0

 encapsulation dot1Q 1 native
 no cdp enable
 bridge-group 1

interface BVI1

You will probably want to have DHCP for wireless clients as well:
