Mac OS X can automatically dial your modem (PPP connection) when it needs to connect to your Internet Service Provider (ISP). For example, Mac OS X will connect for you when Safari or Mail need to access the Internet.
To enable this feature, do this:
- From the Apple menu, choose System Preferences.
- From the View menu, choose Network.
- Click the PPP pane.
- Click the PPP Options button.
- Click the checkbox labeled, "Connect automatically when needed".
If automatic connection does not work
In some situations this feature may not work, even if it is turned on in Network preferences. These include:
When you cancel a PPP connection attempt when the modem is dialing, or you manually disconnect after an automatic connection
To fix this, you can change any modem setting, put the computer to sleep and wake it, change your network location, or restart the computer.
Tip: When this happens, the PPP option "Connect automatically when needed" still appears to be enabled.
After three failed automatic connection attempts
The auto-connect feature turns itself off if a PPP connection can't be made in three attempts. When this happens, it probably means there is an issue with your ISP's phone number, or with the phone cable or outlet. Make sure all the connections are correct, and try a phone with the same cord and outlet.
Tip: In this case, Mac OS X uses the next network port as set in Network preferences (such as AirPort or Ethernet) to connect to the Internet.
Once you have the correct phone number and a working connection, put the computer to sleep and wake it, change your network location, or restart the computer, to use automatic connection.
