El problema de la NIC dice "El enlace está activo/El enlace está inactivo" continuamente

Estoy intentando que mi conexión Ethernet funcione en mi computadora portátil Ubuntu pero por alguna razón la NIC se niega a funcionar.

Probé todo lo que sé, todo lo que encontré en Internet y todavía no funciona.

Aquí hay una lista de lo que probé:

  • Se utiliza ethtoolpara cambiar la velocidad y el dúplex según Supported link modela NIC y la Advertised link modedel conmutador y enrutador.
  • Utilicé tres cables Ethernet diferentes conectados a mi conmutador y cambié los puertos del conmutador. Todos los demás puertos y cables funcionan.
  • sudo ifconfig <interface> up, sudo ip link set <interface> uppero sin cambios.

Esto es lo que dmesg --followregresa continuamente cuando ejecuto estos comandos:

[  916.193910] r8169 0000:01:00.0 enp1s0: Link is Up - 100Mbps/Full - flow control off
[  917.082174] r8169 0000:01:00.0 enp1s0: Link is Down
[  918.678983] r8169 0000:01:00.0 enp1s0: Link is Up - 100Mbps/Full - flow control off
[  919.564996] r8169 0000:01:00.0 enp1s0: Link is Down
[  923.672566] r8169 0000:01:00.0 enp1s0: Link is Up - 100Mbps/Full - flow control off
[  924.556212] r8169 0000:01:00.0 enp1s0: Link is Down

Cuando cambio la configuración, ethtoolsimplemente dice Link is Downy ya no hace nada, especialmente cuando ejecuto autoneg off.

Esto es lo que sudo ethtool <interface>regresa antes de cualquier modificación:

Settings for enp1s0:
        Supported ports: [ TP MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Supported pause frame use: Symmetric Receive-only
        Supports auto-negotiation: Yes
        Supported FEC modes: Not reported
        Advertised link modes:  100baseT/Full
        Advertised pause frame use: Symmetric
        Advertised auto-negotiation: Yes
        Advertised FEC modes: Not reported
        Speed: Unknown!
        Duplex: Unknown! (255)
        Port: Twisted Pair
        PHYAD: 0

        MDI-X: Unknown
        Supports Wake-on: pumbg
        Wake-on: d
        Link detected: no

Cualquiera que sea la velocidad o dúplex que le ponga, no cambia nada de lo que dice Link is Down.

Según los resultados de ethtool, es una tarjeta de 100 Mbps, por lo tanto, r8168 sería el controlador incorrecto. El controlador del proveedor coincidente es r8101. Es mejor comprobar si el firmware está cargado (si la versión de su chip necesita firmware). Útil sería: dmesg | grep r8169
