Heelo.
We have a WLC 2504 with 7.4.121.0 sw version.
We have upgraded to this version due to the fact that with old version many many clients get "duplicated ip address" error.
With this release problem remains.
Frequently clients connects to wifi and get this error, though the error is a fake (I've checked many cases, but there are not duplicated addresses).
DHCP server is the same wlc.
Thanks for any suggestions.
Daniele
