Aironet 340 BSE and DHCP issue

I have set up a home network using Cisco Aironet 340, connecting to a ADSL modem thru a broadband router (USR8000), which also act as a DHCP server, in charge of assigning IP addresses to all my computers.

The Cisco Aironet 340 can accept IP address from a DHCP server. My wireless notebook, used to accept IP address from the DHCP Server(USR8000) thru the Wireless Base Station.

But now, while the base station accept a dynamic ip address from the DHCP, it has also, seems taken over the DHCP function, assign an IP address ( to my notebook. While its associated ip is

My Home network has now being seperated into 2 subnets.

I would like to seek advice on how can get all my computers into the same subnet as assigned by my USR8000 DHCP server?

Thank you in advance.

Re: Aironet 340 BSE and DHCP issue

Any cisco Aironet equipment can't work as DHCP server ( not now) So in your case ip address of the 340 is and workstation associated with it, got received via dhcp from broadband router..Which is very normal..

So "winipcfg" on a PC should report ip address and default gateway as ip address of the ethernet port of broadband from PC you should be able to ping default gateway ip address..

not sure what do you mean by "seperated in two subnets"..

Re: Aironet 340 BSE and DHCP issue

Thank you for your prompt reply.

However, I don't quite agree. My DHCP Server does not issue ip address in segment. It is configured to issue ip address in segement.

This is how they are separated into 2 subnets. My wired node (desktop) is in ip, the router (default getway ) But the 340 is associated in and my wireless node

And from the log of 340, I saw that it was assigned with, but why is the 340 associated with when i open BSCU instead of

All nodes (including 340) are used to be in the same subnet

Your advice please. Thank you.

Re: Aironet 340 BSE and DHCP issue

The BSE-340 and BSM-340 are by default a NAT router. It was designed to have the cable or dsl modem plug directly into its ethernet port and then be a NAT router for a home wireless lan. That is why you are getting double NAT'd currently from the BSE. If you go into the web config you can switch the unit in to a standard access point mode and then it will pull one IP from the dhcp server for itself and pass DHCP client requests on to the server from the clients.

hi ,

this is sandeep

go to log 340.. there you will have the option disable dhcp and after that assign it statically an ip address of range 192.168.123.x and logout from 340.

after that log in your wireless notebook and release ..renew ip.

best of lucks......
