I recently upgraded my network to gig internet. I have confirmed with my ISP that the modem itself is getting the gig speed, and I have confirmed through the TP-Link app that my Deco x20 is getting gig speed when doing the speed test through the app. But when I connect my computer via lan port on the back of the deco with a cat5e cable I can not get past 400mb down hardlined. Am I missing something as I thought these ports were auto detecting but seems they are not detecting or providing the full speed.
