Network Utility

Very helpful to solve my initial question, so now I have Ethernet info on the Network Utility, thank you very much. Now, the need for Network Utility was, and it is, to find clues to the low speed Ethernet, while having cable Cat5e, gigabite router, and I have now the confirmation info on Network Utility that Link Speed is 1 Gb/s. Speed Test however with this MAC is max aprox 150Mbps.

A laptop connected on the same RJ45 cable and the same router has aprox 850 Mbps (download/upload). So, apparently everything is ok with my MAC, I mean info received from the system on hardware/software, nevertheless the actual tested speed is very low. I would be grateful for any new idea.

The story is that I have an Internet provider, also from them I have the gigabite router, and this provider have also their speed test recommended. I was unhappy for a long time by testing the speed, while I have the right equipment and software. Upon my request, today the company replace the router, a better one, and the engineer got on his laptop the expected speed, over 900Mbps. This evening I tested the speed with Ookla, the outcome was the same, about 150Mbps. Suddenly I noticed that Oocla has Speed Test for various Windows, Apple, tablets, laptops, etc. As soon as I selected MAC, I got the right speed for my computer, Download 918Mbps/Upload 922Mbps. My conclusion is that my Internet provider Speed Test is not suitable for MAC. It is a bad news here, because is a very respectful communication Company, TV, internet , mobiles...

Thank you again, everything is allright now !

There is Ethernet connection , all info in System Preferences. More, I have internet on cable and I can turn wifi off, no problem. Yet there is a problem, upon internet Speed Test the values of download/upload are very low, aprox 150 Mbps. This low speed made me check with network utility.
