Quindi sembra che questo modello di d-link ha problemi sulla connessione wifi o sbaglio??
P.S.: Nessuno può rispondere alla mia domanda precedente??
Per le disconnessioni bisogna distinguere tra disconnessioni del router dall'ADSL e disconnessioni del PC wireless dal router.
1) A me non è mai capitato con questo router, però per le disconnessioni dell'ADSL ti posso dire che l'ho configurato così con Alice sia con PPPoA che con PPPoE e va sempre.
PPPoA
PPPoE
In Advanced\Advanced Internet è messo così:
In questa schermata puoi provare a mettere la spunta in SRA Enable per vedere se migliora, togliere AnnexL, oppure a impostare solo G.Dmt o G.Lite oppure fino a ADSL2.
Molte cadute accadono anche per l'MTU scorretto per il provider: Si possono provare anche i valori 1470, 1460 e 1440, ma di solito con telecom non dovrebbe essere necessario.
2) Per le cadute del wireless: qua può dipendere da vari fattori.
- quante reti wireless ci sono nei dintorni e siccome nei condomini e in città ci sono molte reti wireless vicine, conviene indagare quali canali sono più liberi con inssider (che però non vede le reti degli allarmi, dei cancelli etc ...). Bisogna fare attenzione al canale scelto x e al x+4 che è il secondo canale che automaticamente viene usato dal router N e impostarlo manualmente. E' vero che il router sceglie il canale più libero da solo, ma lo fa all'accensione. Se dopo 10 min vengono accesi altri 10 router, il canale è disturbato.
Aggiorna anche i driver della scheda di rete wireless e non mantenere attiva la compatibilità n\g se non ti serve così quei dispositivi non potrenno nemmeno chiedere al router di connettersi. In città arrivano anche decine di richieste di connessione al router al minuto.
Io l'ho impostato così:
In Adwanced wireless i primi 4 parametri possono essere modificati in caso di problemi se ad es si aveva un precedente router con cui tutto andava bene. E' lì che bisogna agire e impostare il router esattamente come il vecchio. Nei driver della scheda di rete, inoltre, bisogna attivare l'opzione WMM (in Qos Setup nel router).
Attiva poi l'aggiornamento ora da internet in modo che il router si colleghi all'avvio per aggiornare l'ora.
Attenzione che se poi l'instabilità del router dipende dalla corrente ballerina della presa con frequenti sbalzi di tensione etc, lì c'è poco da fare se non collegare l'alimentatore tramite una presa elettrica con il filtro. Ma questo vale per tutti i dispositivi elettronici.
P.S.: se abilitate il log del router in modalità debug, si può anche cercare di capire cosa succede:
