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..

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!!
