How to configure the Cisco 851w Router to connect to internet

Here is the Step by Step Configuration

Configure the router as a DHCP server
YOUR_ROUTER_NAME(config)#ip dhcp excluded-address 192.168.2.0 192.168.2.99
YOUR_ROUTER_NAME(config)# ip dhcp pool MY_POOL
YOUR_ROUTER_NAME(dhcp-config)#network 192.168.2.0 255.255.255.0
YOUR_ROUTER_NAME(dhcp-config)# default-router 192.168.2.1
YOUR_ROUTER_NAME(dhcp-config)# dns-server 192.168.1.1
Configure the wan interface
YOUR_ROUTER_NAME(config)# interface FastEthernet4
YOUR_ROUTER_NAME(config-if)# ip address 192.168.1.100 255.255.255.0
YOUR_ROUTER_NAME(config-if)#ip nat outside

Configuring the Wireless LAN Connection

YOUR_ROUTER_NAME(config)# bridge irb //Specifies the type of bridging
YOUR_ROUTER_NAME(config)# bridge 1 route ip //Specifies the protocol for the bridge group.
YOUR_ROUTER_NAME(config)# interface Dot11Radio0
YOUR_ROUTER_NAME(config-if)# broadcast-key vlan 1 change 45
YOUR_ROUTER_NAME(config-if)# encryption vlan 1 mode ciphers tkip
YOUR_ROUTER_NAME(config-if)# station-role root
YOUR_ROUTER_NAME(config-if)# bridge-group 1
YOUR_ROUTER_NAME(config-if)# ssid YOUR_SSID_NAME
YOUR_ROUTER_NAME(config-if-ssid)#vlan 1
YOUR_ROUTER_NAME(config-if-ssid)# authentication open
YOUR_ROUTER_NAME(config-if-ssid)# authentication key-management wpa
YOUR_ROUTER_NAME(config-if-ssid)# guest-mode
YOUR_ROUTER_NAME(config-if-ssid)# wpa-psk ascii 0 YOUR_KEY

Create and configure a radio subinterface
YOUR_ROUTER_NAME(config)# interface Dot11Radio0.1
YOUR_ROUTER_NAME(config-if)# encapsulation dot1Q 1 native
YOUR_ROUTER_NAME(config-if)# bridge-group 1

Configure interface vlan 1

YOUR_ROUTER_NAME(config)#interface vlan 1
YOUR_ROUTER_NAME(config-if)# bridge-group 1

Configuring the Bridge Virtual Interface (BVI)

YOUR_ROUTER_NAME(config)#interface BVI 1
YOUR_ROUTER_NAME(config-if)# ip address 192.168.2.1 255.255.255.0
YOUR_ROUTER_NAME(config-if)#ip nat inside

Configure a default static route

YOUR_ROUTER_NAME(config)# ip route 0.0.0.0 0.0.0.0 192.168.1.1

Configure nat
YOUR_ROUTER_NAME(config)# access-list 1 permit 192.168.2.0 0.0.0.255
YOUR_ROUTER_NAME(config)# ip nat inside source list 1 interface FastEthernet4 overload

Specifies a Name Server to use for name resolution
YOUR_ROUTER_NAME(config)# ip name-server 192.168.1.1
