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 (192.168.200.2) to my notebook. While its associated ip is 192.168.200.1
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?
Any cisco Aironet equipment can't work as DHCP server ( not now) So in your case ip address of the 340 is 192.168.200.1 and workstation associated with it, got 192.168.200.2 received via dhcp from broadband router..Which is very normal..
So "winipcfg" on a PC should report ip address 192.168.200.2 and default gateway as ip address of the ethernet port of broadband router..so from PC you should be able to ping default gateway ip address..
not sure what do you mean by "seperated in two subnets"..
However, I don't quite agree. My DHCP Server does not issue ip address in 192.168.200.xxx segment. It is configured to issue ip address in 192.168.123.xxx segement.
This is how they are separated into 2 subnets. My wired node (desktop) is in ip 192.168.123.189, the router (default getway )192.168.123.254. But the 340 is associated in 192.168.200.1 and my wireless node 192.168.200.2.
And from the log of 340, I saw that it was assigned with 192.168.123.139, but why is the 340 associated with 192.168.200.1 when i open BSCU instead of 192.168.123.139?
All nodes (including 340) are used to be in the same 192.168.123.xxx subnet
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.
