Ethernet port and Samsung smart tv

[Comp0za]

For some reason, when I have plugged in the ethernet cable on my Samsung Smart TV, the eth led port indicator on the xr500 router is red. As the picture is showing, I'm using 4 eth LAN port, but switching to the other LAN ports, led indicator is red as well.

Red means the device is connected with 100mbit instead of 1000mbit.

 

Smart TV's generally have 100mbit ports so it's normal.

Great answer from @Bert, spot on.
