"00:22:fb:89:d1:dc DHCP successfully bridged packet to DS" means that you have dhcp proxy disabled on this controller.
If DHCP Proxy is disabled, then the controller is no longer involved in the DHCP process and this is requiring you to have IP HELPERS in place on your router to get these dhcp requests to the correct server.
If you want DHCP Proxy enabled (so that you can use the DHCP configuration under the interface or the WLAN on the controller) you can do "config dhcp proxy enable"
In 4.1, disabling DHCP proxy did just that, it disabled the "proxy". If you ever look at your dhcp lease of a wireless client, it comes from a dhcp server of 126.96.36.199 (virtual IP of the controller). With proxy disabled, the address will no longer be masked.
In 4.2 and beyond, disabling dhcp proxy actually disables the DHCP Relay that is the process of the controller sending the dhcp requests to a specified server.
So if in 4.1, you had "dhcp proxy" disabled, in 4.2 and beyond, you are actually disabling the relay as well.
If this is indeed the case, enable dhcp proxy, or add an IP Helper adress to your router for this vlan, just like you would normally do for Wired clients.
