Using AIR-AP1231G-E-K9 as repeater


I have an AIR-AP1131AG-E-K9 running as root AP with three SSID's (mbssid), all WPA-2 PSK, IOS 12.4(25d)JA

Now I would like to use an AIR-AP1231G-E-K9 as repeater for one of the SSID's (all three are AFAIK not possible), IOS 12.3.8-JEE(ED)

So only one SSID is used.

I use exactly the same shared secrets and security settings on both devices, on the repeater the SSID is designated as infrastructure-ssid.

Unfortunately I have the problem that the repeater AP cannot associate with the root AP.

I have verified that aironet extensions are enabled, same security settings are used and checked many sites on the net which describe how to configure a repeater AP. 

Is there any incompatibility between these two APs?

I have two of the AIR-AP1231-G-E-K9 APs available, do I need to use the same models?

Best regards,

Is infrastructure ssid on the root as well?

It wasn't. infrastructure-ssid requires to be enabled on the vlan 1

I need to change the VLAN settings to make it work.

Testing the setup with the native vlan ssid, I get the error message WPAIE not found and required.

Is WPA-2 recommended to be used with the 1231 APs?
