Please I need your help. I have a Mikrotik’s OmniTIK U-5HnD and it looks like the master lan port is turned off. Please help me, what sohuld i do ?
What do you mean “turned off”? Are the other LAN ports “turned on”?
The OmniTik default config is set as an AP, ether1 being WAN and firewalled (http://forum.mikrotik.com/t/cant-connect-to-omnitik-u-5hnd/57044/1). This might be what you are having problems with. Try powering OmniTik on ether1 and plug another cable into ether2 to log in and change config:
