I just spent a couple hours re-discovering something strange wit ip pools.
My natural tendency to specify a class C subnet is to enter 192.168.x.x/24.
The system accepts this but does not work for hotspot pools! (my html directory gets ignored and the hotspot directory is used)
However, specify a pool as 192.168.x.5-192.168.5.50, and everything works fine. Suggestion for new routerOS version: don’t accept my first specification for and IP pool in winbox!
