Unlikely, the symptom you get in that case is that EtherK fails to
detect the Ethernet chip on the motherboard, which is not happening in
this case.

Yes, probably a good idea to try resetting the switch. The EtherK output
in your mail shows that as far as EtherK is concerned everything is OK.
The link is up, it's been detected as 1000BaseT, and the driver is
transmitting and receiving packets with no errors.
As well as resetting the switch, I'd suggest swapping the Ethernet cable
in case it's faulty - sometimes it's the simple things that go wrong. If
you're convinced that the switch and cable are OK, try "*EKInfo -v" and
look at some of the more obscure statistics to see if they give any
hints of something amiss - the EtherK user guide file (which should be
somewhere on your hard disc) explains what they mean (to an extent). If
that doesn't get you anywhere, try forcing the link speed to 100M and
see if that helps.
