Level 6 (9,324 points)
Servers EnterpriseHaving reinstalled OS X from scratch we can initially presume it is indeed a hardware issue. Things to try next are -
- Try the other network socket on the Mac Pro (it has two)
- Try a different network cable
- Try a different network socket
If non of the above help then it may be the chip rather than the socket or cable, in which case as the chip is soldered on to the logic board you would need to look at getting a different network adapter. This could be a USB one or a PCIe one. See the following for examples.

Jan 26, 2016 12:00 PM in response to Energeeby Grant Bennet-Alder,★HelpfulNetwork Utility (included with Mac OS X) can read out the error counters associated with a particular link to see if it is accumulating errors. There should not be more than an initial small burst, and growing numbers (even very slowly growing) indicate a problem:
If you cannot find it, you may have to chase it down from:
/System/Library/CoreServices/Applications/Network Utility.app
I find it helpful and use it often. It also tells you the actual speed of your Ethernet connections, rather than the configured speed. The other panes include a GUI-faced Ping and many others.

Jan 26, 2016 11:40 AM in response to Grant Bennet-Alderby Energee,Hello guys,
Thanks for the input.
I have reinstalled OS,changed cables, even changed location of the machine to a different power source.
I have confirmed that both of the gigabit (82574L) ethernet ports on my MacPro are problematic. Somehow the connection freezes or gets interrupted.
I agree that my last solution would be to purchase a new NIC, but perhaps there's anything else to try?
Is there any change that the PCIE SSD creates some kind of problem? Or maybe dust inside the machine?
Any other ideas to try?
You can see attached a screen while downloading a 1GB file, got 2 received errors.
On the other port where I have the interface connected (avid artist control) there are zero errors.
Thanks
Alex

Jan 26, 2016 1:05 PM in response to Energeeby Grant Bennet-Alder,That link states it is running at 100Mbit/sec.
To run at Gigabit speeds, all cables must have all eight wires in them (none may be used for power-over-Ethernet) and all devices must support Gigabit speeds.
