Cisco 877w che da problemi con le connessioni HTTP
Inviato: sab 14 feb , 2009 5:10 pm
Ciao a tutti...
Ho un problemino con il mio 877w, e non riesco proprio a capire dove c'e' l'errore... Anche perchè circa la stessa config ce l'ho su un 1801 dove lavoro e la va tutto a posto... Ho provato con tutte le ios che ho trovato (12.4 20t, 12.4 20t1, 12.4 22t, sta sera provo con la 12.4 15t8), ma da sempre lo stesso problema.
Spesso i browser dietro di esso non riescono ad aprire le pagine, faccio un refresh e tutto va a posto. Non riesco a capire se è un problema dns o se è un problema delle connessioni in generale... La comunicazione da me al router è ok, se metto un ping fisso verso fuori è ok (anche con dimensioni alte, tipo 500byte), ma nei browser (avevo ie6 ma ora sono passato a firefox ma fa la stessa cosa) mi da sto maledetto problema. Magari mentre apro una pagina mi carica meta' immagini si e meta' no, oppure non mi apre per niente la pagina. Premetto che ho emule semrpe attivo, ma il router non è sovraccarico e non segnala errori nei log
Questo è un sh ver:
Questo uno sh mem stat
Questo un sh proc cpu | ex 0.00
Ed infine, questa è la config:
Che ne dite???
Grazie mille!!!!
