The device is a Mikrotik Hex S. I have a 1Gbps up/down fiber connection that is connected to an ONT and the Mikrotik is connected to this ONT. The connection is a static WAN connection not PPPoE. Port eth2 is set up as the WAN interface with the static IP configured. When I run a network test using the public btest server from the Mikrotik directly, I get speeds of about 900Mbps up and down, as expected.
Now, eth3 is configured as the LAN port on the Mikrotik, when I connect a laptop/computer to this eth3 port and do an iper3 test or normal speedtest, I am unable to go beyond 600Mbps. What could be causing this? I have fasttrack enabled on the LAN traffic, barely any firewall rules, no QoS nothing, and still this.
Config is as below.
