Hi, Jonas,

UBNT RS has two ports connected to eth1, port 0 and port 1. If you connect
your Ethernet cable to port 0 without first connecting Ethernet cable to
port 1, it won't work. You will see a lot of messages "Trying 100/FULL,
Trying 10/HALF, Trying 10/HALF". Once you connect port 1 with Ethernet
cable, you will only see the message "eth1: link up (100Mbps/Full duplex)"
and the port 0 will function properly.

Do you know why?

Regards,
Chun Yeow
