Cisco 800W WiFi configuration example

Cisco 800-series devices have embedded AP in them.

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
Network: 10.23.45.0/24


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

bridge irb

interface Dot11Radio0
 no ip address
 !
 encryption vlan 1 mode ciphers tkip 
 !
 ssid WiFi-SSID

interface Dot11Radio0.1
 encapsulation dot1Q 1 native
 no cdp enable
 bridge-group 1

interface BVI1
 ip address 10.23.45.1 255.255.255.0
 ip nat inside
 ip virtual-reassembly

bridge 1 protocol ieee
bridge 1 route ip

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


ip dhcp pool WiFi
   network 10.23.45.0 255.255.255.0
   default-router 10.23.45.1 
   dns-server 8.8.8.8 8.8.4.4

Don’t forget to add new wireless network to your NAT rule, in order to reach out the Internet.
