Thanks Seth for your workaround, it does work but it is A LOT slower compared when I use the default Search preference "Active, historical clients + All devices" vs "Active Clients + All Categories".
The default search setting "Active, historical clients + All devices" return the result back in 4seconds while the other one returns back the device list "All AP & controller in one list" in 16seconds (4 times slower) and the rogues list is even slower "around 40seconds". Do need the rogue list? Most probably not, in most cases. It doesn't look like we are making it more efficient and more user friendly, are we?
Just my 2 cents.
