PPPoE works through router but not in Windows

[karserasl]

Well its a really strange problem..

My ISP (digi.hu) offers cable internet. Up until 2 days ago i could just plug the cable directly to PC and use the build-in PPPoE connection of Windows and get internet.

Now it just shows Error 651. But the thing is that i can connect to internet through the router.

I tried 2 different PC Win 8.1 and 7, linux but nothing works.. The router is a simple router with PPPoE functionality nothing special but it works while Windows doesnt.

Any1 have any idea?

Thanks

Contact the ISP and have them check your settings.
