 +**ANTECEDENTES**
 +
 +Tenemos una tarjeta de red, y queremos saber si soporta velocidades de 10000mbps ('gigabit')
 +
 +**SOLUCIÓN**
 +
 +(Como root)
 +
 +1. Suponiendo que la tarjeta de red sea 'etho':
 +
 +  dmesg | grep eth0
 +  [    1.990066] e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
 +  [  536.704969] e1000: eth0: e1000_watchdog: NIC Link is Up 10 Mbps Half Duplex, Flow Control: None
 +  [  758.407797] eth0: no IPv6 routers present
 +
 +En este caso va a 10mbps = mojón
 +
 +Mejor instalar ethtool que te dice todo lo que soporta y a cuanto está ahora:
 +  #apt-get install ethtool
 +
 +  # ethtool eth0
