I have encountered a problem with Winbox. My laptop has two network cards - wired and wireless, both connected to the same switched network, served by one Mikrotik. The problem is that winbox sees my Mikrotik only if I have only one network card connected/running. If I have only wireless connection, all is OK, if I have only wired connection and wireless is turned off, all is OK. When I have two connections up and running, internet works OK, but winbox doesn’t see my Mikrotik.
it is not prefered to make 2 simultanoes connections to same network form one device. in case you amge that - device gets confused - if you have bridgetd wlan end eth - set stp or rstp to manage loops in network, that it hsoudl work ok, but will use only one connection to connect.
My experience is this:
Any MAC-level protocol (MAC-WinBox, MAC-Telnet) does only work if you have only ONE (active) network interface on the machine WinBox is running on.
Connections to a router using an IP address (of course) always work.
I suppose this has to do with the fact that the MAC-level protocols work by broadcasting, and things get messed up when there is more than one interface…
But I cannot answer details to this question - this would be left to MikroTik. For the moment it seems to be a fact that you may only have one interface active when using MAC level connections to your RouterOS devices.
