please try to load the latest driver of i218-V for your system, you can check the link below:
if problem still persists, try setting the "gigabit master slave mode" on advanced properties of your network adapter to "force master mode".
the ethernet cable you're using should be CAT 5e or higher to ensure gigabit connectivity.
hope this help.
Thanks so much for your response. Unfortunately I tried both of these steps, but without any luck.
The cables that I'm using are a pair of brand new Belkin Cat5e cables, so I guess there should be no problem there.
Hi FatChocobo, aside from the system with i218-V, any other systems on your network that connects to the same switch with 1Gbps? What is the brand and model of the switch?
I have a similar problem. I can only do 10 Mpbs Full with powerline ethernet adapters. 100 Mpbs negotiates, but ping times are 2-3 seconds. I have 3 different powerlne adapter brands and all of them have trouble with my new T450s. I have atleast 3 different PC and laptops at my home and none of them have trouble with the powerlne adapters. I checked other forum threads and this problem seems to be open.
