Problémy s ethernetem

[Jiri463]

Ahoj, aktualizoval jsem z Kubuntu 12.04 64bit na Kubuntu 13.10 64bit. Aktualizace proběhla v pohodě, ale poté mi začali problémy s ethernetem. Prostě mám ve svým Lenovu Y580 připojený eth. kabel a najednou internet padne a znovu se snaží připojit a často se mu to ani nepovede. Občas se to stane i při spuštění počítače. Nemáte tušení co s tím? Díky.

Podíval bych se do /var/log/syslog ve chvíli, kdy to vypadne, tipl bych, že odpověď, nebo alespoň směr se najde tam.

Jestli to padne a potom se to pořád dokola připojuje, zkusil bych vypnout správu napájení té karty, tohle mě vyváděl MacBook

[Petr Merlin Vaněček]

Nějaké novinky?

Popravde ani nevim co tam hledat, ale tady je kratky usek co mi to pise v syslog:
