Vista RAS PPPoE Driver and save it in the C:\Windows\system32\drivers folder. Once this process is complete, restart your PC to activate changes made.

Solution 3
Try Power Cycling your Modem and your Router
Before you try this solution, it is recommended that you save all your work on your system, close all open applications and then shut down your PC.

After that, turn your router off and wait for about 2 minutes. Then turn off your modem too. Now disconnect all the Ethernet cables that are connected to your modem, router and your system.

Reconnect them again and make sure that the connections are not loose. After reconnecting the cables, reboot your PC and switch on the modem first. After your modem gets initialized, turn on the router. See if this procedure works.
