Windows Phone was not vaporware, it was real ... shit. And that's why it disappeared real soon ...we all hope that it will not be vaporware like Windows Phone...
Actually the proper way is to adjust /interface list member ports grouped in LAN list ... and WAN as well if WAN port is not the default one. This would fix firewall filter rules, NAT rules, MAC server rules ... all at the same time.(adjust LAN to your interface name)
/ip dhcp-client set [ find interface=ether1 ] disabled=yes
First of all check what is the negotiated speed on the ethernet ports ...
/interface ethernet monitor <port name> once
I just found out that there are 2 mikrotik sharing same MAC address.
Is that really where we have gotten with long-term releases?
