Hello. I have a managed switch. D-LINK DGS-1100-08.
My internet speeds, download / upload are 100 Mbps.
Using speedtest.net, I get the correct download / upload speeds, but using testmy.net, the download speed is correct, but the upload speed it's about 3.5 - 4 Mbps.
Also, the real world speeds are the same as the tests from testmy.net.
What could be the problem?
Of course, connecting directly to the router, the speeds are correct, only through the switch I have the problems.
Thank you in advice.
