Debian prekinjanje povezave

Na enem izmed strežnikov imam inštaliran Debian in zadnje nekaj dni opažam, da se povezava z internetom večrat dnevno prekine in server je tudi kakšno uro offline. V logih sem opazil tole:

Sep 20 08:12:56 localhost kernel: [236059.500059] tg3: eth0: Link is up at 100 Mbps, full duplex.

Sep 20 08:12:56 localhost kernel: [236059.500062] tg3: eth0: Flow control is on for TX and on for RX.

Sep 20 08:24:21 localhost kernel: [236744.443531] tg3: eth0: Link is down.

Mašina je povezana na router in drugi računalniki normalno delajo.

Mogoče kdo ve kaj bi bil problem zato?

Tole ti link dol pada.

Jaz bi sumil slabo mrezno ali pa port na switchu. Si probal zamenjati?

Preveri se kable + sam sem imel primer ko sem imel 10cm od ruterja en racunalnik, da se je nekaj podobnega dogajal.

Bom za začetek probal zamenjati port in kabel. Upam, da bo že to dovolj. Hvala
