Ho un 877 "vissuto", cioè l'ho preso già usato, ho dovuto poi sostituire i condensatori di alimentazione che si erano gonfiati (nessun problema lavoro con l'elettronica) e l'alimentatore che era difettoso.
Utilizzo in utenza domestica con alice 7Mb
Ultimamente mi capita che il router diventa instabile (non riesco a navigare o raggiungere le altre macchine della lan) o peggio ancora come stamattina che dopo essermi svegliato presentava solo il led della eth0 acceso (unico cavo di rete connesso) il resto tutto spento.
Vi chiedo gentilmente se qualche esperto può analizzare la mia configurazione per capire se il problema sta lì oppure se mi devo rassegnare e buttare il router dalla finestra per altri problemi hardware.

So che potrei caricare una configurazione terra-terra e vedere se il problema persiste.
Vi ricordo inoltre che ho piallato a zero l'877 pochi giorni fa ricaricando poi la configurazione.
Spero si possa risolvere, nel caso peggiore sappiate che sono disposto ad acquistare un nuovo cisco, accetto suggerimenti e proposte sempre per un 877 con il quale mi ci trovo benone.
