Cisco 851W - PPPOE

Unanswered Question

I'm trying to setup my Cisco 851W to connect to my DSL Modem with a PPPOE connection.

I tried using the SDM Internet (WAN) option and enabled the PPPOE option with a Dynamic IP Address with both Chap & PAP, but cannot get access to the Internet.

If I try to set it up with a Dlink Router, I have no problem getting to the Internet.

Is there a way to monitor the connection to my PPPOE account with the Cisco 851w?  I don't see any errors under "show log"

Do anyone know of a good document on how to setup PPPOE with the Cisco 851w?

Thanks in Advance

You should open nre threads for new probelsm.

Anyway, your ISP may have a MAC lock, ask them to remove it or leave router off for a night or so.
