It happens on two computers and I tried about 5 or 8 times (each without
success) before looking into it and replacing cables.

That's interesting, too, but different from my case. My network card(s)
are recognized and only the link cannot be established.

For that reason I wrote a hook (confdir.DEFAULT.jook) that waits up to
10 seconds for 'eth' to come 'LOWER_UP' (using 'ip link show up'). In
most cases the network is up in under 3-4 seconds. In the mentioned
cases waiting even longer doesn't change anything.

Yes I will. It isn't 'really' serious since I can work around - it's
just somehow 'myterios'.
And as Thomas said ' Anyway, always check the cable if you
have network problems ;-)'
