Salve guru e ben ritrovati
Problema del giorno (mai farsene mancare uno!)

- realizzata rete Lan per portare collegamento internet in altra mia postazione (7km)
- pc all'arrivo (dual boot win xp - Ubuntu 12.10) destinato solo alla LAN (ovviamente solo Ubu!!)
- primi due mesi funzionamento regolare
- da qualche giorno continue sconnessioni, sempre più frequenti;
- verificati, nell'ordine: router, lan ed ISP;
- router e lan OK; verifica dell'ISP (h24) non ha evidenziato problemi;

supposti problemi alla di scheda di rete ho eseguito test di sistema che indica “stato device disattivato" – pur non comprendendo come potesse funzionare ugualmente – ho attivato e rieffettuato il test:

Su altri due pc le sconnessioni non avvengomo!!!!

Grazie anticipate e scutemi la lunghezza del post.
