No connection with Asus RT AC 68U

Hi @Rene_R_Wenzel ---- Thank you for the follow up and verifying that information for me.

If I am not mistaken the TP Link SG108E is a managed switch and we have seen a few issues crop up with these devices in the past ( Example: #1, #2, #3). I would recommend enabling flow control on the switch, as we have seen it help other users.
