Hola themax, eletrovox e tutti
qualche mese orsono, con la vs. collaborazione, ho realizzato la rete seguente:
pc "A" -m/r D-link --> Ap1 > STA1/STA2 > STA3 > Ap2 --> pc "B" + area wireless (3pico)
- provider TeleTu - protocollo HTCP auto - firmware 5.5.2.
tutto perfettamente funzionante!!
Da circa una settimana - problema:
a) in “A” - impalli del router - rimedio OFF/ON e tutto torna OK;
b) in “B” - sconnessioni di due-tre secondi e spontanee riconnessioni;
Controlli effettuati da “B”
- verifica configurazione router - OK;
- eseguito reboot - apparentemente - Ok;
- verifica sincronizzazione router/adsl - OK;
- autenticazione client su internet - OK;
da 3 gg. router non più problemi ma in “B” disconnessioni/riconnessioni, anche a clic apertura pagine web, continuano
Altri controlli effettuati, sempre da “B”
- Uptime di ciascun apparato - non risultano sconnessioni/riconnessioni tranne in una nel cui log... (vd sotto (*))
- dbm delle "sta" - sempre minore di – 85
OUT - forse ho le traveggole ma giurerei che una sera (in “B” - aera wireless) un notebook ha continuato a lavorare anche mentre il pc filare era andato in out per sconnessione.
Log di cui non mi convinco (stante che Uptime regolare)

Domanda:
- i riporti log sopra indicati sono riferibili alle disconnessioni?
- se si qual'è il problema
- altri controlli/procedure eseguibili per individuare la causa dell'anomalia e chi (lungo la rete) ne è responsabile?
a presto leggervi e grazie come sempre
