1240 AG Set-up as Repeater Problems

I have two Cisco 1240AG routers. One is setup as an AP and the other is setup as a repeater to the host (AP). Both of these have static IP's in the same subnet (192.168.1.X). Once the repeater is powered up it does broadcast the signal and connect fine, but it is spitting out an IP address (169.254.X.X) that will not work within our network. I thought it would spawn DHCP through the host. Does anyone know how I can get the repeater to give an IP address of (192.168.1.X). I have tried entering in commands to point to the DHCP server and also for the DHCP IP pool, but nothing seems to work. Any suggestions would be appreciated.

Thanks!

Re: 1240 AG Set-up as Repeater Problems

How are your ap's configured.... repeater BVI interface is on the native vlan? if you can associate to the root ap and get a dhcp, then at least we know that that side is configured right. Have you confirmed that?

Re: 1240 AG Set-up as Repeater Problems

Yes, the repeater can associate to the root AP, but when I connect a handheld to the repeater it is giving me the wrong IP address. I used an IP-helper command to associate my DHCP server with the repeater, but it still gives me the wrong IP. I need it to configure an IP within the range of 192.168.X.X. It gives me an IP of 269.254.X.X. Since it is giving me an IP in the wrong pool of address's I cannot connect my handhelds to the network from the repeater. This is my first experience with Cisco routers so I do not have as much experience with them...I appreciate any suggestions you can give! Thanks!

Re: 1240 AG Set-up as Repeater Problems

Can you have a laptop or one of your handhelds connect to the ROOT AP first and verify that that device associates and get the correct DHCP address?

Re: 1240 AG Set-up as Repeater Problems

Yes, I can connect a laptop and all of my handhelds to the root AP with the correct pool of IP addresses (192.168.X.X). As soon as I connect them to the repeater it spawns a new wrong IP (269.254.X.X)

The SSID you are associated to with your handheld (on the root ap), is that the same SSID your repeater ap is associating to?

Yes it is...same SSID, same WEP encryption, and same MAC address filters.

Re: 1240 AG Set-up as Repeater Problems

The 169.254.x.x is a default ip address the client creates when unable to aquire a dhcp address. I would suggest you post your configurations so people can take a look.
