Mhh what about to send me a new one, and I send mine back?
Hi @eviltrooper
Sorry to trouble you.
From your description, I suspect that there is a problem with the RJ45 connection, but from this picture,I’m still not sure RJ45 is connect ok or not, please help me to confirm this:
-
your routers and cable could work normally at other device(such as PC), right?
-
please help me to take a picture to show the network chip,i want to check if any conductive objects have fallen into the pins of the network chip.
-
use something to check the RJ45 all pin is already connect ok.
be careful that: use a little force, but not too much. if RJ45 connect not ok,the pin will move a little bit.
from your dmesg, I wonder why RX is 0, but it can be assigned to an IP address 
I did some test, but never meet your situation.

Is it possible to check a short circuit between 1, 2, 3 contacts? Can I take a clearer photo of this place? Defect VIM3
Sorry cant make better photos.
Very similar to spreading solder paste, try scrubbing with a wooden toothpick and rinsing with ethanol (ethyl alcohol) or another similar rinsing liquid.
i try it… will not work.
i try it on my work with Cisco Switch. my DHCP want to give the VIM a IP. but he doesnt take it. because of no RX bytes.
i tried it with 100Mbit
my VIM3 has a physical error… 
i never see this before… only on a defect Lan Card.
Hi @eviltrooper
