When PPPoE or PPPoA is used, the Router becomes the PPP client, that is, all the
software needed to establish and maintain the connection is located on the Router.
ISPs frequently require PPP client software to be installed on workstations. If any
computers have PPP client software installed on them, this software must be
removed or at least disabled before the computers are able to connect to the
Internet through the Router. If you are required to provide a User Name and
Password every time you access the Internet, your computer may have PPP client
software installed on it.
