<div align="left" style="text-align:left;"><font face="Arial" size="+0" color="#000000" style="font-family:Arial;font-size:11pt;color:#000000;">Il mio PC è un MSI Wind Nettop 120X; l'access point un D-Link DAP 1160; la scheda AR5007EG 802.11bg WI-FI mini PCI express card; il sistema operativo Opensuse 11.3. </font></div>
<div align="left" style="text-align:left;"><font face="Arial" size="+0" color="#000000" style="font-family:Arial;font-size:11pt;color:#000000;">All'inizio ho provato a configurarla sia con DHCP, sia con indirizzo statico, ma non funzionava. Nelle Impostazioni di Rete di Yast la scheda risultava connessa, nella configurazione rilevava l'ESSID automaticamente, tramite la scansione di rete. Però non funzionava. Pingando sull'indirizzo dell'access point o su quello del router, la risposta era sempre HOST UNREACHABLE tranne che sull'IP della stessa scheda, che invece dava risposta.</font></div>
<div align="left" style="text-align:left;"><font face="Arial" size="+0" color="#000000" style="font-family:Arial;font-size:11pt;color:#000000;">Seguendo alcune indicazioni che mi sono arrivate anche dal forum ho proceduto così:</font></div>

<div align="left" style="text-align:left;"><font face="Arial" size="+0" color="#000000" style="font-family:Arial;font-size:11pt;color:#000000;">A questo punto ho provato a dare il comando:</font></div>

<div align="left" style="text-align:left;"><font face="Arial" size="+0" color="#000000" style="font-family:Arial;font-size:11pt;color:#000000;">Come ho detto all'inizio però è rimasto un problema, che il nuovo modulo cioè non viene caricato al riavvio e quindi ad ogni riavvio la connessione non va. E' necessario tornare in Yast/configurazione scheda di rete/modifica e poi salvare pur senza fare nessuna modifica e la connessione si riavvia. </font></div>
<div align="left" style="text-align:left;"><font face="Arial" size="+0" color="#000000" style="font-family:Arial;font-size:11pt;color:#000000;">Come faccio a far caricare la nuova configurazione automaticamente all'avvio?</font></div>
