Hi All, I am having a weird issue with my TL-ER5120 in that i cannot set the port under switching to 1000MB Full-Duplex, there is no option for that in the drop-down menu. I purchased this as it clear

My isp requires to disable auto negotiation on my wan port and set it to 1000mbit and full duplex. In the web config i am inname to set port settings to 1000mbit komt 100 and 10 are possible settings.
