My DSL service’s PPPoE is always disconnecting.
PPPoE is not actually a dedicated or always-on connection. The DSL ISP can
disconnect the service after a period of inactivity, just like a normal phone dial-up
connection to the Internet. There is a setup option to “keep alive” the connection.
This may not always work, so you may need to re-establish connection
periodically.
STEP 1 To connect to the router, go to the web browser, and enter http://192.168.1.1 or
the IP address of the router.
STEP 2 Enter the password, if asked (default password is admin).
STEP 3 On the Setup > WAN menu, select the option Keep Alive, and set the Redial
Period option at 20 (seconds).
STEP 4 Click Save.
If the connection is lost again, follow steps 1 and 2 to re-establish connection.
