Hello,

I have this problem on some Hardware CCR1009, RB3011UiAS, etc.

The PPPOE Session is establisht and work fine for some hours or days. And than the Rx traffic stop working, you don't see any traffic on this.

Router OS doesn't notice that, so it has done manuel deactive and active the PPP Interface. Than it works fine for some time.

Is there anythink, what I can do? All Routers has the news Firmware.

Regards
Oliver

No idea everyone?

Are you talking about client or server connections? It's problematic to give you an advice without detailed information.
If you are the client, first ask your ISP about this.
