Cisco 1811W configuration

I have connected to a brand new Cisco 1811W via the SDM and via the console.

I would like to set up FE0 for a wan connection to the internet and setup DHCP available on all Ethernet ports and lastly setup 1 WIFI SSID.

I have tried this numerous times but each time I end up defaulting the router again due to issues. 

Does someone have a somewhat "default" configuration with 1 WAN, DHCP and 1 WIFI enabled?

That would make this so much easier.

Thanks!

Re: Cisco 1811W configuration

Ok.. lemme help you out on DHCP and the WIFI..

Assume VLAN 1 is used for the wired and the wireless clients and the DHCP pool..

en

config t

ip dhcp pool

network

default-router

end

Eg -

ip dhcp pool WIFIPOOL
   network 192.168.10.0 255.255.255.192
   default-router 192.168.10.1

The above will take care of the DHCP..

now wireless..

en

config t

bridge irb

bridge 1 protocol ieee

bridge 1 route ip

int dot11 0

ssid

encryption vlan 1 mode ciphers tkip

vlan 1

end

en

config t

vlan 1

end

en

int vlan 1

bridge-group 1

end

en

config t

int bvi 1

ip address 192.168.10.1 255.255.255.0
no shut

end

en

config t

int dot11 0.1

encapsulation dot1Q  1 native

bridge-group 1
end

This above config will get  the wireless network up and running.. we need to make sure that the NAT is enabled and configured so that the clients who grab the IP can reach out to the internet..

Now regarding the wired clients getting the IP from the same pool...

we need to put all the layer 2 ports in vlan 1.. ie.. configure them as access port..

ex- fa 4

en

config t

int fa 4

switchport

switchport mode access

switchport access vlan 1 (not needed since it will be in vlan 1 by default)

end

the above will do it!!

Regarding the WAN.. the below link may help you..

non Cisco link but... various examples are provided..

http://www.networkstraining.com/category/cisco-800-series-routers/

make sure you are not assigning the IP to interface VLAN 1.. since we are using the same for BVI and bridging the traffic..

Let me know how the above works out for you!!

Surendra
