Ethernet disappeared randomly after Mavericks installation.

Hi,

Mavericks seems to have killed my Ethernet port on a 2012 (mid) MBP 13".

I have re-installed, reset PRAM and SMC to no avail. It was there 2 days ago. There has been no trauma to the unit at all.

Is there a way to test this port / fix it without replacing the logic board? thanks.

Try removing/rediscovering and adding it in Networks from System Preferences. Verify it shows up in network under System Information
