I've just been upgraded to 200mbps and sent a Superhub 2ac unit which has 4 gigabit internet ports.

I run a late 2010 iMac 21" which is also capable of gigabit ethernet, I have a 12ft Cat5e cable between the units.

The Mac network card is autodetecting at 100base t an connecting ok. If I manually 'force' the card to 1000base t I get the dreaded 'Cable unplugged' alert.

I can get ~200mbps over 5.0ghz WiFi so Shub is capable of the spec speed.

Any idea why the ethernet card is not detecting the gigabit ports? Is the fault with the Mac or the Shub?

Cheers.
