PPPOE WAN Authentication with CenturyLink

[Aaron Ezekiel]

I'm having problems getting the WAN side of my ASUS RT-AC66U running Merlin 380.59 to authenticate with CneturyLinl VDSL over an ActionTec C1000a DSL modem in bridged mode. II'm trying to switch to bridging-only mode so I don't effectively have 2 routers in front of my home LAN. I know I have the correct PPPOE username and password, but it will not connect and give me a working Internet connection.

And some syslog samples:

Suggestions? I posted this same info in a much older thread about the same kind of PPOE WAN authentication issue, sorry if that's a no-no....

One guy suggested using code from a couple of the forks from the Merlin code. I'm uncomfortable with that for several reasons too long to discuss here.

I'm fairly sophisticated at networking, having been in a big research university computing center as a systems analyst for several years. Would much rather get it working in current Merlin code...

Please don't crosspost the same question in multiple thread, it makes it impossible for anyone to follow up the discussion.

Sorry, after I posted on that old thread, I was afraid it was too old and would never get seen!

Won't do it again. I'll pick up discussion over there.
