I searched it in google and people say that this mean the ruter disconetc but i want to known why the ruter disconnect and what is the solution¿?

My ISP is Telefonica Spain and the ruter´s configuration is the standart to this ISP. I used a Telefonica´s ruter and Internet goes fine.

Sometimes if I am connected to a phisical LAN port I lost the connectivity.

Someone can help me¿?

Thks
