TL-SG116E 1.20, Hardware version not an option in pull down forum message. Ports are setup with LAG1 ports 1/2, LAG2 ports 3/4, and LAG3 ports 5/6. Both of my NAS devices have dual GBe ports, and my PC has a Intel I350 dual GBe card setup with Intel pro utility. LAG does not work, if any device has a second cable plugged in, that device can't be detected by any other device or access the internet.

I've read that the SG116E has known problems, one of which is LACP is not supported only static LAG.
