When I connect a client to the mikrotik RB2011 I see the router-name "Mikrotik-XXYYZZ" in the network interface overview. The last 3 tuples are the last three from the wireless MAC from the mikrotik router.
Under system I set the router name to "test". Moreover, the default ssid from the wireless NIC is also called "Mikrotik-XXYYZZ", but I also changed it to test but the ethernet ID does not change.
Where is this parameter hidden?
