Does your PC 'see' your network connection?
If it does, open your web browser and enter the following link to your router set up utility.
Select 'LAN settings' and set DHCP server to 'on' and set lease time to forever.
Select 'Connection Type' and select 'PPPoA'(unless someone can tell you AOL is different!)and enter your user name and password for your AOL account.
Select 'IP assigned by ISP' to 'Yes', tick 'dial on demand' and set idle time to zero. All your settings are then provided automatically by AOL.
If you still can't connect it could be a cable connection problem or firewall settings.
