PPPoE with Cisco 851.

Unanswered Question
Feb 8th, 2007

I'm trying to configure the 851 router to auth with PPPoE and it doesn't seem to work. I put all the settings with PAP authentication (ISP = Sympatico), yet it can't get the connection to work. I've tried with the SDM Express without success, then, downloaded SDM and installed on the router hoping to get more configs, still doesn't work. I've also put my user as [email protected]

Could it be the modem not taking the commands or something, i'm totally clueless regarding this issue, since i'm not very familiar with the 850 series router.


I have this problem too.
