It takes 15 seconds between the two messages until it becomes ready. I
have no idea why it first says that the link is not ready.
It's probably autonegotiation of link speed. I'm not sure why it'd
take that long. I'd think the most likely explanation would be a bad
cable. Could also be a flaky port on the switch, or a flaky Ethernet
card. What brand is the local interface?

I'll check the cable (not clear how I can do that, probably using
another cable and connecting to another outlet).
I think the local interface is directly integrated into the Intel
Desktop Board DH87RL.

It says that it has a speed of 10/100, but I definitely expect 1000 Mbps!
