mac mini wired internet download speed

My fibre wired broadband speed is 500Mbps.

But I can only get wired 200 Mbps download speed with mac mini(late 2014) OSX Yosemite 10.10.5. Upload is 488Mbps.


My other HP laptop can get wired 400Mbps download speed.


Pls advise as I understand mac mini can support up to 1Gbps speed.


thank you

Mac mini (Late 2014), OS X Yosemite 10.10.5

PS and Mac speedtests are tested at same time. Very interesting is Mac download speed only 200Mbps whereas Mac Upload speed is 490Mbps.

My Service Provider said speed difference between Download & Upload should NOT be such BIG gap ! He suspect network card problem ??


AppleCare are also puzzled and currently investigating this issue...


Will update Community once root cause is found and solution given to resolve this issue.

Thanks for yr support.

Ok, this will be your "baseline" settings.


I would like for you to try the following, in order, and test the results. After testing, return the configuration back to the baseline:

  • Change Configure to: Manually (you don't need to return back to the baseline after this step)
  • Change Duplex to: full-duplex
  • Change Duplex to: full-duplex, energy-efficient-ethernet
  • Change Duplex to: full-duplex, flow-control, energy-efficient-ethernet
  • Change Speed to: autoselect
  • Change Speed to: 100baseTX
  • Change MTU to: Jumbo (9000)
  • Disable "AVB/EAV Mode"

All the settings still give only 198-202Mbps download and 467-487Mbps upload speed.

If set to 100baseTX, only hv 79Mbps download and 35Mbps upload speed.


Applecare service centre did a hardware diagnostic test and found NO problem.

I clean install OSX El Capitan 10.11.6 per their instructions but download speed still around 200Mbps !

Awaiting their further advise.

To measure data throughput on your local network between two devices will require that you use software on both ends. iPerf is typically used for this but requires knowledge on both using it and its Terminal commands. A simpler way would be to use a utility that has a graphical user interface. There are numerous ones out there, but one you can try (& is free) is TamoSoft Throughput Test.


This test software comprises of both a server and client version. You will need both to run the tests.

  • Start by downloading the software from the above link.
  • Install the client on your primary computer, and the server on the other computer on your network that you want to test the Ethernet connection to.
  • Start the server software: TTServer
    • Leave the default port setting.
    • The server will now be in listening mode.
    • Note the IP address in the bottom window of the server. This will be the address that you will connect the client to.
  • Start the client software: TTClient
    • Enter the server's IP address in the "Server IP or IPv6 address" field.
    • Click on Connect.
    • After a short while the two applications will connect and start providing data throughput results.
    • You should see data transfer throughput results for both the UDP & TCP IP protocols across the connection in Mbps.
    • For Gigabit Ethernet, UDP should be nearly 1000 Mbps, TCP slightly less. The Loss values should be a very low percentage.
