When you attempt to use Internet Connection Sharing (ICS) with a Digital Subscriber Line (DSL) connection, it may not work correctly on the host or client computer. You may receive a time out error message when you attempt to browse the Internet, or your network adapter may not be recognized when you try to install ICS.
Some Internet service providers' (ISPs') Digital Subscriber Line (DSL) connections use a software virtual adapter known as a Point to Point Protocol over Ethernet (PPPoE) adapter. This adapter is not recognized by ICS as an adapter that is available to be used.
NOTE: If ICS is installed, please uninstall before continuing.
For ICS and Internet Explorer to function properly using a PPPoE adapter, ICS must be configured in the following manner:
Start Internet Explorer, click Tools, and then select Options.
Click Connections, and then click Always dial my default connection.
Under Dialup Setting, make sure that the connection to the DSL's ISP is selected as the default connection.
Click OK, and then quit Internet Explorer.
