Is it true that the HotSpot feature can be used only on ethernet interfaces?

The HotSpot feature in MikroTik can indeed be utilized on interfaces beyond just Ethernet. This flexibility allows it to be set up on wireless interfaces as well, enabling users to control access to network resources in various environments, including both wired and wireless networks.

For example, when deploying a HotSpot in a public space such as a café or library, it's common to set it up on a wireless interface to provide customers with internet access after they authenticate through the HotSpot login page.

Using HotSpot on wireless interfaces expands the potential applications of this feature, supporting various scenarios where users require controlled access to the network. This capability is crucial for ensuring that access management is effective, regardless of whether the users are connecting via wired or wireless methods. Thus, the assertion that the HotSpot feature can be limited only to Ethernet interfaces is inaccurate, supporting the conclusion that the answer is no.
