Cable Modem, DSL, and LAN Internet Connections
Make sure all modem cables are fully plugged in. Check the modem power cord, the
cable from the modem to the computer, and the cable from the modem to the wall
jack. Also check the cables and power supplies for Ethernet hubs and routers.
Turn the modem off and on to reset the modem hardware
Turn off your DSL or cable modem for a few minutes, and then turn it back on.
Some ISPs recommend that you unplug the modem’s power cord. If your modem has a
reset button, you can press it either before or after you turn the power off and on.
Important: Instructions that refer to modems do not apply to LAN users. LAN users
might have hubs, switches, routers, or connection pods that DSL and cable modem
users do not have. LAN users should contact their network administrator rather than
an ISP.
PPPoE Connections
If you are unable to connect to your Internet service provider using PPPoE (Point to
Point Protocol over Ethernet), make sure you have entered the correct information in
Network preferences.
To check PPPoE settings:
1 Choose Apple () > System Preferences.
2 Click Network.
3 Click Add (+) at the bottom of the network connection services list, and choose PPPoE
from the Interface pop-up menu.
