La risposta di Geraard dell'utente in questo post sul forum potrebbe aiutare. Le modifiche alle impostazioni suggerite sembrano aver risolto il problema:
- Click the Apple Icon at top left of your screen.
- Select
System Preferences
.
- Select and open
Network
- At the lower right select
Advanced
- This will bring up the
PPPoE screen with a menu bar showing TCP/IP, DNS, WINS, Proxies, PPP
- Select
PPP
to access the drop down menu and then you can make
changes. On the SECOND LINE PROMPTS: I change the value from 0
minutes
to 999
minutes. This cured the Pop-up Message to Reconnect that was
happening.
Il supporto Apple sembra concordare:
If you keep disconnecting from the Internet
If you have to redial your dial-up modem Internet connection after not
using your computer for a few moments, or reconnect your PPPoE
connection, your computer may be set to disconnect automatically
when the connection is idle.
- Choose
Apple menu > System Preferences
, and then click Network
.
- Select your modem port (internal or external) or your PPPoE configuration from the Services list, and then click
Advanced
.
- Click
PPP
, and then make sure the “Disconnect if idle for __ minutes”
checkbox is not selected, or if it is selected, increase the
number of minutes before that the computer will remain idle before
disconnecting.
Con un po 'di fortuna, questa modifica delle impostazioni risolverà il tuo problema.
