Hello,
please assist me. when i try to push traffic on this mikrotik ether1, i only get 10mbps. the cable is fine and the link is 20mb.
when i go to interfaces/ether1/bandwidth rx/tx i only see 10M as max limit. even setting 20M doesn't not work. what could be the problem?

How do you know "the link" is 20mb? I'm guessing that whatever is reporting that is showing you have a duplex link at 10mbit/s so you can 'push' 10mbit while also 'pulling' 10mbit, making 20.

i have a vast link with 7mb up and 20mb down. the mikrotik only allows 10mb up and 10mb down under ether1 interface then bandwidth limit.
