Q: Unable to get 1000base t ethernet on iMac
My ISP has upgraded my internet connection to 200Mbps.
All I could get was +/-85Mbps.
On checking my Network settings I found the ethernet set to "automatically detect' with all other settings greyed out but speed was 100base tx.
Selecting "manual" and selecting "1000base t" causes it to disconnect and give the "Cable Unplugged" alert.
Rebooting doesn't help. I have correct cables.
How do I get it to change to 1000base t?
TIA,
Russ
