how are you testing it? If this “speedtest” is via something like the Speed Test Kodi add-on then it will not give anywhere near an accurate result for anything other than very slow connections. This is an issue on all platforms and even Kodi on a fast PC has the same issue. Also that would be more of a test of your connection to the internet and not your LAN connection anyway even if it worked. If your testing your actual wired connection via something like iperf then this would not be expected behavior on a Vero 4K+.
