I switched from xfinity cable to CenturyLink fiber.

CenturyLink fiber works with the ZyXel router they supplied. I want to use my Buffalo wzr-hp-ag300h. The Buffalo router worked fine for xfinity cable.

CenturyLink fiber uses PPPoE. Just putting in my PPPoE user name and password into the Buffalo router is not enough -- after doing that, the router cannot connect.

I attach print screens of the ZyXel router broadband (WAN) setup pages. I cannot figure out how to set up the Buffalo router with DD-WRT.

My Buffalo has DD-WRT v3.0-r37305 std 10/1018

Assistance would be greatly appreciated!

I will transfer this thread to the appropriate forum for you.

Furthermore you are using an old and obsolete build, forum guidelines will show where to get recent builds.

Main problem could be that you need to set the WAN on vlan 201 but I am no vlan expert

First, please consider upgrading; current release as of this post is 47528.

Second, depending on output of swconfig list and what device is the WAN, the following example may help:

OK I upgraded to 47528.

Where do I find that setting?

[kernel-panic69]

How about we start here. Via telnet/ssh to the router, show us the output of 'swconfig list'. It is always assumed that you know to use telnet/ssh for command line, and apparently, you are not aware of this.

Based on the output from my wzr-hp-ag300h
and my lack of knowlege here I would say @k-p69's terminal commands are probably correct.
Just my 2 cents

[Per Yngve Berg]

No, it looks like the WAN is on VLAN 1.

[kernel-panic69]

Good catch, PYB. Of course, I don't understand why all the ports are using pvid of 1?

From defaults config, the correct commands would be:

[Per Yngve Berg]

It looks like the wan is not on the switch at all.

[kernel-panic69]

It's time for me to see the eye doctor; I missed that, too. Then there is a device not listed and perhaps using the vlan tagging in webUI would need to be employed or something. I tried.

[aardvigator]

OK, making progress but not successful yet.

[Per Yngve Berg]

The WAN is not on the switch. It shows only 4 ports.

Can you do a "ifconfig"?

[aardvigator]

I attach a screenshot, the output of ifconfig
