Hi everyone.
The problem is very simple, when I use wi-fi I get 100mbps on speedtest.net
When I use ethernet cable, I get 30mbps.
I tried different cables and PCs and got the same result.
If change the speed here Imgur: The magic of the Internet to 1Gbit, the ethernet ports stop working.
If I change it to 100mb full duplex, I still get 30mbps max.
Just 1 more question, do you enable QOS to limit different VLANs bandwidth usage ? Just worry you may miss that settings actually limiting Ethernet LAN client speeds.
