Hello,
is possible with routerOS the have multiple hotspots on the same machine and the AP attached to the switch (far from the hotspot server)
I need something like this:
A hotspot is tied to routed interface. It is possible to have multiple hotspots running on one RB, but they need to be on separate broadcast domains. This can be done by using separate hardware and ports on a MT, or with VLANs. It all depends on your needs and what kinds of equipment you have.
