1941W Wireless config

Unanswered Question
Apr 23rd, 2012

I just purchased a 1941w router to see if we want to use this to replace our existing routers and external access points. At each of our locations we have 1  subnet that has a server, AP, router, switch, etc.

I would like to configure the AP and the router in the 1941w in the same subnet but cannot figure out how to do this. If I setup the wlan-ap0 interface with an IP in the subnet I am using it will not let me assign an IP from that same subnet to any of the ethernet interfaces. It says they overlap.

No matter what I do I cant seem to use the same IP on both. I could if I purchased a 1941 without wireless and then purchased an aironet so why cant I do it when they are in the same box?

I'm not a cisco expert so I assume I'm just not doing something right. Any help appreciated.


I have this problem too.

You need to configure a bridged interface that is linked to your ethernet-interface and your wlan-ap0-interface. On the bridged-interface you set the IP-address. Search on cisco's website to set it up.

Thank you for the reply but when I try to bridge the wlan-ap0 interfae it says it does not support bridging. This is the command I used:

bridge-group 1

This isthe output I get

wlan-ap0 does not support bridging

Any other ideas?

You need to create a vlan en BVI interface in you're config


ip dhcp pool LAN-WiFi

import all




domain-name WORKGROUP

lease 7




interface wlan-ap0

ip unnumbered BVI1

arp timeout 0

no mop enabled

no mop sysid


interface GigabitEthernet0/0

no ip address

duplex auto

speed auto

no cdp enable

bridge-group 1

hold-queue 100 out


interface Vlan1

no ip address

bridge-group 1


interface BVI1

ip address

ip nat inside

ip virtual-reassembly in

no ip route-cache


and do not forget

bridge 1 protocol ieee
bridge 1 route ip

in you're AP config you can set both ( 2.4 and 5Ghz ) to the vlan1

now the LAN and WLAN have the same IP range.
